#1 Re: Human missions » space x going to the moon instead of mars » Today 14:02:48

A ship using ion propulsion can boost itself into a stable GEO without any crew aboard, and then a minimally loaded Starship V3 can dock with it at the far edges of Earth's Van Allen Belts, where radiation exposure is minimal.  At 100kg per crew member, 100 crew members represents a 10t payload per Starship, aboard a vehicle that nominally delivers 200t to LEO and 15t to 25t to GEO, without refueling.  That is more than sufficient payload performance to reach GEO.  The time spent spiraling out from GEO to TMI is minimal.

If Starship V3 still requires 1 refueling event to return to Earth with an acceptable performance margin, then that still makes more economic sense than refueling it a half dozen times or more to send a Starship all the way to Mars.  That means in-space electric propulsion is both feasible and practical using a modest but meaningful modification to how we perform crew transfers to larger / heavier / slower / but better-equipped interplanetary ships with artificial gravity and mass margins for additional crew provisions.

There is no hard requirement for the interplanetary ship to perform impulsive maneuvers to clear the Van Allen Belts swiftly when nobody is aboard.  From a ship design standpoint, it's better if interplanetary ships don't perform impulsive maneuvers because then they don't need to withstand an additional set of significant mechanical loads applied to them by high-thrust engines.

If your propulsion options allow you to maximize speed or payload, go for payload.  Enormous carrying capacity precludes the need for speedy transits.  The slow boat to China still makes it to China, and still arrives carrying an enormous payload.  We need bulk freighters to safely send people to Mars, not Ferraris.

If we insist on using LOX/LCH4 or LOX/LH2 propulsion, then over 90% of all the mass we deliver to orbit for Mars missions, assuming Earth orbit to Mars orbit and then back to Earth orbit transportation, is propellant.  Using electric propulsion achieving an Isp of 2,500s or greater, at least 50% of the mass we ship can be anything except the propellant.  If one of the primary mission objectives is to deliver things other than propellant, then in-space electric propulsion is a non-negotiable hard requirement.

It's not practical to build these enormous AI data centers in orbit and do Mars missions when every Mars mission requires at least a half dozen flights per outbound transit.  At some point, our fuel consumption starts impacting other sectors of our economy, and that's where the Mars missions will end, because someone will invariably point out that there is no massive immediate economic return on investment.  A Mars colony is a slow-burn investment into the future of humanity through enhancement of our reach into our own solar system.  A large Mars colony is a long term side-hustle that pays off in the mid to far future, likely in ways we don't yet fully comprehend.

All the tech applicable to a Mars colony will eventually pay into real-life Star Trek starships that we can use to colonize planets orbiting nearby stars.  If we don't have the interplanetary transport and colonization tech ready to go by the time AI figures out how to bend spacetime, then we're going to squander another 25 to 50 years experimenting with how to live on another planet before we can do anything at all with our snazzy new Star Trek "real-life starships", apart from taking pretty pictures.  All the "baby steps" we take to get to that point are just that- a toddler learning to crawl-walk-run.  Capitalizing on existing and emerging electric propulsion is merely one more of those baby steps.

SpaceNut,

If leftists want our Police to treat them more humanely, then they should stop chasing them around, throwing things at them, spitting on them, vandalizing their vehicles, threatening to murder them in their sleep, and threatening to murder their families.  Those are not the behaviors of someone who wants "de-escalate" anything.

#3 Re: Not So Free Chat » Politics » Yesterday 14:45:01

SpaceNut,

What I care about is that the State of Minnesota's Governor, the Minneapolis Mayor, and a lot of Somalis, all took part in a TEN BILLION DOLLAR MEDICAID FRAUD!

Only Democrats actually care about skin color, which is why they talk about it all the time.  Everyone else is waiting for Democrats to course-correct to a set of core governance principles that don't involve blatant criminality.

If every single one of the people we imported from Somali were blonde-haired blue-eyed bikini team models, and they were involved in the same fraud schemes, then I would still want to deport every last one of them.

America is not going to become an "anything-goes" communist dystopia because a minor fraction of the population wants to agitate for it on the basis of irrationality and general ignorance of history.

You know who absolutely does deserve American citizenship?

All those Afghanis who fought for America, and for their own freedom, that President Biden's administration straight-up abandoned to the Taliban, should have been scooped up and spirited away from the hell hole the Taliban created.

How about all the Kurds and Yazidi who fought tooth-and-nail against ISIS?

Surely they are more deserving of the privilege of being an American than the repulsive assortment of rapists and murderers President Biden's administration imported into America.

RobertDyck,

EJ230 for Gripen E

From Reddit user "Live_Menu_7404":

There has been a recent report by Global Defense Corp on YouTube claiming Saab will offer the Gripen E with the Eurojet EJ230 instead of the F414-GE-39E/RM16. Is there any truth to this claim? Is it feasible and sensible from a technical standpoint and what would this entail? What are the associated risks?

From Reddit User "RobinOldsIsGod":

That proposal goes back to the late 1990s, when Germany first proposed replacing the Gripen-C's RM12s with EJ230s. Typhoon was supposed to have thrust-vectoring engines, but those were canned due to budgets. Damn shame too, that would have made the Typhoon f'n awesome. But today? AFAIK, the EJ230 doesn't actually exist beyond a prototype taken to trade shows.

Now, sticking an EJ200 in a Gripen-C would be a godsend to that plane as it's got more thrust than the Gripen-C's RM12. But putting an EJ230 into a Gripen-E would likely result in a thrust loss. Not only does the EJ200 produce about 2,000 lbs less thrust than the F414/RM16, but thrust vectoring nozzles makes the engine itself heavier. That ain't great when the Gripen-E is already roughly the empty weight of a Blk 30 Viper but only has about 80% of the the Viper's thrust. Thrust has always been a LIMFAC on the Gripen series. The Dassault Rafale is basically what Gripen should have been; slightly larger with a much larger weapons and fuel load and generally better performance.

Outside of angry Canadians (just everyday people, not anyone with actual knowledge) reposting each other and having a crisis over the idea of EJ-powered Gripens and one YouTube channel with AI V/O that damn near gave me cancer...I can't find any corroboration to Global Defense Corp's claim. Maybe this is something that Saab has pitched again to drum up sales interests after Citrus Caligula's F-47 comments, but even Saab knows that their delta-winged Ikea F-20 is not in the same category as the F-35, much less a a twin-engined, 6th VLO fighter or even the KF-21 for that matter.

Remember those CFTs that were demo's on a Super Hornet a few years back? Know why you never see them in use? Because the Navy didn't fund their development. And even though there was interest from some potential foreign operators, they weren't willing to foot the bill for them once the Navy passed on it.

So Saab can offer it all they want, but someone's going to have to pay for the EJ230's development from prototype to production engine and the integration of it in the Gripen-E/F and all the associated flight testing.

Honestly, it's 2025 and Gripen first flew in 1988. This would have been great in the 90s on Gripen-C, but here we are on the verge of 6th Gen GCAPs. Sweden should have stuck with that instead of trying to get more blood out of this stone.

GE offers an up-rated F414 as well:

RobertDyck,

The United States is becoming the world's largest banana republic.

We have a lot of Somali illegals to feed these days.  If we don't become the largest banana republic, then they're going to starve.  We do a lot of things to people, but letting them starve to death isn't one of them.  BTW, you forgot the "and rice" part.  We're becoming the largest "banana and rice republic".

#6 Re: Not So Free Chat » Politics » Yesterday 12:38:52

RobertDyck,

I got this from a report by a former ICE officer.

I have a former top NASA official who has a report that says the moon is made of cheese.

In the case of Renée Good, she was a citizen of the US, born and raised there, and the ICE agents knew it. That meant ICE did not have authority to arrest her.

ICE agents are sworn federal law enforcement agents.  If you deliberately interfere with their operations, they have the authority to apprehend and arrest you.  You are free to disagree, but I take my legal positions from the US Supreme Court, not Canadian leftists making absurd statements about laws they are clearly ignorant of.

After he was disarmed, he was shot in the back 10 times.

If a criminal has one weapon that you found, they may have other weapons you haven't found.  It's really hard to determine what weapons someone does or doesn't have on their person when they're resisting arrest.

Again, ICE does not have authority to arrest a US citizen, they certainly don't have authority to murder anyone.

The US Supreme Court disagrees with your personal interpretation of who ICE may apprehend and arrest, or any other law enforcement agency for that matter.

I agree that ICE may not murder anyone, but nobody was murdered.  Shooting someone resisting arrest while using a vehicle as a weapon or carrying a weapon is not considered murder, in much the same way that shooting someone who is trying to shoot you is not considered murder, either.

The US Supreme Court has already issued opinions on these matters.  Your personal beliefs about what the law should be or how our laws should be interpreted are not affirmed by case law precedent.

#7 Re: Not So Free Chat » Politics » Yesterday 12:06:56

RobertDyck,

To be clear, there is absolutely no need for ICE to exist. At all.

I'm quite sure every illegal alien criminal would agree with you, but this is why Americans determine what law enforcement agencies we require to enforce our immigration laws, rather than foreign nationals.

Without a bank account, how do I pay utility bills?

You don't need a bank account to pay bills.  There are numerous people living in America who have never had a bank account during their entire adult lives.  The fact that you're unaware of this is how I know that you don't know much about the subject matter.

So I'm saying the US doesn't need thugs with body armour and guns.

We don't need any thugs, which is why ICE is deporting the illegal alien thugs that the Biden administration allowed into America by not enforcing our immigration laws.

It's all accounting, done in an office.

If the banking and accounting world was as neat and simple as you portray it, then most organized crime would be impossible, but this is not how the real world works.

#8 Re: Not So Free Chat » Politics » Yesterday 11:38:55

SpaceNut,

Does US law prohibit foreign nationals from entering the US who are already violent convicted felons in their country of origin?

Yes, U.S. immigration law generally prohibits foreign nationals from entering the country if they have been convicted of crimes involving moral turpitude, including violent, serious felonies committed in their country of origin or elsewhere. Such convictions typically render individuals inadmissible under the Immigration and Nationality Act (INA).

Key details regarding this prohibition include:

Aggravated Felonies: Convictions for murder, rape, sexual abuse of a minor, or illicit trafficking in firearms/explosives are permanent bars, making entry or legal status nearly impossible.

Crimes of Moral Turpitude (CIMT): Violent crimes (e.g., manslaughter, kidnapping, robbery) often fall under this category, which triggers inadmissibility.

Drug-Related Offenses: Any foreign conviction for drug trafficking or controlled substances makes a person inadmissible.

Waivers: While some, rarely, may qualify for a 212(h) waiver if the crime was long ago, no waivers are available for severe crimes like murder or torture.

Documentation: Foreign nationals must disclose these convictions during visa applications, and background checks are conducted to identify criminal history.

#9 Re: Not So Free Chat » Politics » 2026-02-07 21:33:25

SpaceNut,

Assaulting a vehicle warrants a police report of vandalism call to 911 not direct untrained actions of a tantrum as if he owned the vehicle.

Vandalizing a government vehicle was the least of Pretti's criminal behavior.  When Pretti decided to punch ICE agents, that was the moment his behavior went from obnoxious outburst to violent felony against federal law enforcement officers.

I am not arguing about whether immigration laws should exist and not just how they’re enforced.

Minnesota's Democrat leadership was afforded every opportunity to hand over violent illegal alien criminals at their own jails.  They refused to cooperate with federal law enforcement after they were caught stealing federal money, and instead decided to create a bunch of domestic terrorist cells.

Good and Pretti were garden variety leftist whack-a-loons looking for a cause to join, and because Democrats can't resist a good crime spree, Walz and Frey and other far leftist activists in Minnesota's local and state government organized, funded, and encouraged their criminal behavior.

Why did they do that?

They don't think the law applies to them, no different than any other criminal.  They think they're entitled to what better men and women have created through their own hard work.  This belief is nothing new amongst criminals.  It's timeless.

Immigration agencies were built for: border interdiction, fugitive operations, tactical raids

Not:

public‑facing enforcement, civilian interactions, de‑escalation,  proportionality in mixed crowds

All law enforcement agencies are public-facing.

All law enforcement agencies interact with civilians.

All law enforcement agencies have dealt with crowds of rioters.

The military, for the most part, is non-public-facing, and was not designed or intended for law enforcement operations.

So the mismatch produces exactly what you saw: unnecessary confrontation, poor judgment, avoidable escalation, behavior that looks unprofessional

Walz and Frey directed their local and state law enforcement agencies to refuse to cooperate with ICE.  If leftists truly want de-escalation, then they should stop interfering with ICE agents doing their jobs.  I don't think that's what Minnesota's leftists actually want, though, and the proof is found in their behavior and rhetoric.

“These agents are doing a job they were not trained for, and the public is paying the price.”

You really should take that up with Walz and Frey.

#10 Re: Not So Free Chat » Politics » 2026-02-07 18:59:34

RobertDyck,

ICE are not police.

False.  ICE agents are sworn federal law enforcement officers.

Your line of reasoning on this is about as intelligent as stating that a FBI agent can't pull over and arrest a drunk driver because the legal limit for intoxication varies from state-to-state.  They can and they do, when they have to.  Our courts have already ruled on this matter.  Your creative interpretation of what you think should happen doesn't affect what will actually happen to you if ICE vs FBI vs State Trooper pulls you over for DWI.

Where do you get this crap?!? Alex Pretti did not assault any officer. You appear to be living in a bubble of disinformation.

Yes, you are living in a bubble of disinformation.

I posted a video of Pretti assaulting federal law enforcement officers.

Here it is again since you missed it the first time:
Associated Press -  New video shows Alex Pretti in scuffle with federal officers days before his death

The claim that Alex Pretti assaulted an officer is a deliberate lie.
...
He did not assault any officer, he was just murdered.
...
Whatever source is telling you he assaulted an officer is deliberately lying to you, so stop listening to them.

The video footage from The Associated Press is not a lie, it was not made up for sake of argument for or against anything, but it shows Pretti seeking out and assaulting ICE agents, vandalizing their vehicle, and then assaulting them while armed with a handgun.  He repeated that same pattern of violent behavior 11 days later.  I don't care what parts your "protesters" chose to film or not film.  He did the same thing twice and was shot the second time he did it.

You are changing the subject. And when Obama was President, ICE did not have teams of thugs roaming the streets, abducting people off the street.

One of the two federal law enforcement officers who shot Pretti was first employed in his federal law enforcement role under President Obama.  When President Obama was President, Minnesota's local and state governments and law enforcement agencies were cooperating with the President so that ICE agents didn't need to go door-to-door to arrest and deport people who had already been arrested by local and state law enforcement officers after they committed various violent crimes (rape, robbery, murder) against people living in America.  That is "what changed" when President Trump became President, because Walz (Governor of Minnesota, Democrat) and Frey (Mayor of Minneapolis, Minnesota, Democrat) decided they no longer had to comply with federal laws.

I'm not defending Obama, he did a number of things I disagree with.

Nobody was asking you to defend President Obama's actions.  I did ask why you said nothing about ICE deporting illegal alien criminals under President Obama.  Your response tells me you don't know what's going on now and didn't know what was going on when President Obama was in office, either.

But Trump is the only President to authorize armed thugs to abduct people off the street, whisk them to El Salvador without trial.

False.

Arrest and deportation can take place at the local jails or we can send ICE agents door-to-door to find and arrest violent illegal alien criminals after they've been released on bail by local and state law enforcement officers.  The people ICE has been deporting have already had trials, and have already been convicted of multiple violent crimes, which is why they shouldn't have been allowed to infiltrate into America to begin with.  In other words, the criminal behavior of these illegal aliens ICE is arresting did not start or end in America.

I live in Canada.

I didn't forget where you live, not that you'd ever let anyone forget that you're Canadian.

I have to remind you that US officers and agents have no jurisdiction in Canada.

Since this entire conversation has been about what's going on in America, it should've been obvious that what I said applies to America, where ICE absolutely does have jurisdiction.  You've been to America multiple times, according to you, and since you cannot seem to distinguish between your personal beliefs about our laws and law enforcement vs real application of law enforcement, I was providing instructions related to how to not get yourself killed while interacting with American law enforcement officers.

If I didn't care about what happens to you, then I wouldn't bother with correcting your media-induced misconceptions about our laws.

#11 Re: Meta New Mars » kbd512 Postings » 2026-02-07 15:41:00

SpaceNut,

If that structure was wrapped around the outside of the torus, then it provides a stiffer and stronger support structure without resorting to using tubing with 8mm wall thickness.  If we have a 20m inner diameter torus pressurized to 21.75psi (14.5psi * 1.5 safety factor), then the hoop stress with 2m (78.74in) thick Hesco barrier type walls (the minimum regolith shielding required to absorb most of the radiation dose) is 130.5psi, which equates to 202,275 pounds of force, or 91.75 metric tons-force per square meter (130.5psi * 1,550in^2 per square meter).

Hoop Stress / Circumferential Tensile Stress = PD / 2t
P = Internal Pressure
D = Diameter
t = wall thickness

Keep all of your units consistent.  If you decide to use metric, then it's Pascals (Pa) for internal pressure and meters for diameters and wall thicknesses.  If you decide to use "people who have been to the moon" units of measure, then internal pressure is measured in terms of pounds-force per square inch (psi) for internal pressure and inches for diameters and wall thicknesses.

#12 Re: Not So Free Chat » Politics » 2026-02-07 14:29:48

RobertDyck,

We’ve been over this before, and you refuse to learn.

For your own physical well-being and continued existence on this Earth, and specifically because I value your life, if an American Police Officer tells you that you are under arrest, if you are driving a vehicle then stop the vehicle and turn off the engine when they tell you to do so.  Do not physically assault them.  All of your absurdly childish beliefs about what they should do are not going to protect you from the consequences of resisting arrest.  I can and will show you multiple videos on YouTube of criminals who did exactly what Renee Good did, and most of them were shot dead.  A few survived and are now serving lengthy prison sentences.

You're defending the abhorrent behavior of radical leftists who went out of their way to attempt to prevent ICE from arresting child rapists and murderers because you hate President Trump.  In your worldview, you think it's "more moral" to attack and harass law enforcement officers who are upholding the law than it is to stop violent criminals from continuing to prey upon American citizens and other illegal aliens alike, most of whom are leftists.

Ana Kasparian is one of your fellow leftists, a typical Californian hippy-dippy-doo-dah, but after she was raped by an illegal alien, she had a "brain reset" when the only person who demonstrated any care or concern for her well-being was, in point of fact, someone who voted for President Trump.  Since she only discovered this long after he helped her, her anti-logic programming loop was finally "broken" by her inability to "reject reality".  Her brainwashing didn't have the opportunity to paint the man who helped her as "the enemy" because he didn't share his political opinions with her because she never asked him.

I believe citizens should be allowed to own a gun, should be able to defend their home. But carrying a gun in public is asking for trouble. I disagree with both open carry and concealed carry. However, the US has chosen to make it legal. Once it’s legal, you can’t shoot someone for just having a gun on their person.

If you choose to follow law enforcement officers around while armed, and then proceed to assault them while resisting arrest, the most probable outcome is that they shoot you.  Whether you accept that this is the case or not, I'm telling you it's the most probable outcome.

ICE is harassing individuals in states that voted Democrat in the last election.

You have that backwards, my friend.  ICE is being harassed in Minnesota because Republicans won the last election and are once again enforcing our immigration and fraud laws.  As a citizen, there is no absolute right to harass law enforcement officers performing their lawful duties, simply because you disagree with what you think our immigration and fraud laws should be.  The legislature and the courts are the proper places to resolve differences of opinions over our laws, not the streets, and certainly not by seeking out and initiating violent assaults against law enforcement officers.

ICE is actively operating in all States of the Union, not just Minnesota.  There are plenty of ICE agents here in Texas.  I've seen some of them in public.  The only major difference is that here in Texas our local and state governments, whether run by Democrats or Republicans, do not fund and operate local domestic terrorist cells, because they don't tolerate interference with any law enforcement operations, irrespective of the politics involved.  Houston is a Democrat-run city.  Our state's governor is a Republican, but almost all our major cities are run by Democrat politicians, not Republican politicians.  Here in Texas we all seem to agree that we do have laws, they will be enforced, and as always, you are free to leave if you want to live some other place where the laws mean nothing because they are not enforced.

ICE is Trump’s Gestapo, and they’re murdering people.

You have repeatedly failed to tell me why ICE wasn't President Obama's "Gestapo", so I will assume that you have no answer to provide.  People who make completely absurd arguments about their indefensible positions never seem to be able to provide such answers.

When President Obama was using Predator drones to launch Hellfire missiles at American citizens who were not even suspected of any crimes, you did not say one word about it.  They were never given the mere opportunity to surrender to law enforcement.  That is what a real government-sponsored murder looks like.  I've pointed this out multiple times and have received radio silence from all leftists on this forum.  That tells me what I need to know about you.  You either think our government can do no wrong when your favored political party is in power, or your application of basic logic is highly inconsistent because it's driven by political beliefs and personal prejudices instead of higher reasoning.

Since there is no consistency to your complaints about America's government whenever Democrats are in power, in the absence of any statements from you, I will assume this is purely related to your prejudiced personal political beliefs and feelings towards President Trump, specifically, and Republicans in general.  I will continue to retort with basic logic, facts, and reasoning.

If you ever begin demonstrating logical consistency by criticizing the exact same actions taken by Democrats, then your words may carry more weight with me.  Until then, you come off as a typical leftist political hack who has no real issue with the same law enforcement actions executed by Democrat-run governments.

#14 Re: Life support systems » Bogs and Bog, Floating Island Technology, and Roller Solar. » 2026-02-06 15:52:36

Void,

All the concepts I've seen from you seem to involve "floating" the lens on the surface of the water, but I'm talking about suspending the lens above the water so that it's not subject to unintended deformation from wave action.  This is just an idea that may or may not work for any number of reasons, not something I've completely thought through.  It struck my fancy because it's reasonably simple in theory, can be purely mechanical by using mechanical sun trackers, and uses low cost materials for construction.

Edit:
Maybe the correct analogy for the silicone lens, rather than a "breast implant", is actually a multi-cell "air mattress" which contains fresh water.

#15 Re: Life support systems » Bogs and Bog, Floating Island Technology, and Roller Solar. » 2026-02-06 15:47:37

Void,

If you have a clear polymer and fresh water, can you make some kind of giant selectively deformable "water lens" to evaporate sea water, collect the minerals, and extract the fresh water from the ocean?

I'm thinking of something like an enormous "breast implant", for lack of a better visual representation, rather than a "contact lens", and you use mechanical / hydraulic power to "deform" said lens to optimally concentrate the sunlight.

Why the "breast implant" vs "contact lens" approach?

You can control concentration of the sunlight in a way that isn't practical with a single lens and would otherwise require some sort of "giant telescope" precision lens alignment which would make the device much more expensive than a fresh water filled silicone membrane that can give you just enough power concentration to flash the water to steam in a controlled manner.  It's much less of a "solar death ray" than it is a slow but immensely powerful hydraulic cylinder that delivers just enough "photonic force" to the surface of the sea water to get the job done, without going overboard with the power concentration.

The size of this device could be enormous, secured to a shallow sea bed offshore using steel hydraulic cylinders sunk into the bedrock, which are then used to deform the membrane, as required, to optimize beam intensity and size.  I was thinking of using some layers of flexible plastic underneath it to collect and route the fresh water and mineral rich brine.  That's another reason why we don't "death ray" power, because it would melt the collector plate plastic.

The "benefit" to this style of fresh water and mineral brine collection is that it can be a fundamentally simple mechanical device with minimal moving parts.  Apart from the lens support / lens deformation hydraulic stanchions arrayed around the periphery of the lens, there's very little metal required, temperatures aren't completely nuts so it wouldn't kill the marine life below it, and over time we could "mine" truly enormous quantities of light (Sodium, Calcium, Magnesium, Lithium) and heavy (Uranium) metals.  The carbonates would supply CO2, and maybe we could devise a method to collect the dissolved CO2 as well.

Maybe you already thought of this.  If so, then disregard.  I just thought it would be a neat "low-tech" way of getting fresh water and large quantities of light aerospace and battery making metals.

SpaceNut,

Re: 304L strength and stiffness problem resulting in excessive tube wall diameter:
The temperatures outside that crater can reach up to 21C during the daytime in summer, even though temperatures can plunge to -100C at night, which means those year-round frosty cold temperatures only apply inside that crater.  That means my idea about keeping the 304L very cold probably won't work.  At -100C, 304L's YS is near 50ksi vs only 28ksi at 21C.  The AI is therefore correct about using room temperature yield strength values for 304L.  I should've known that there would be no easy way for us to exploit that massive temperature drop at night.

Ask the AI about increasing the tube diameter and/or using a triangular tubular support vs a single tube.  We have a stiffness problem, so let's see if something like this will help solve it:

Re: Calliban's Basalt Casting Process Post
Yes, I read Calliban's post.  It would seem that very high temperatures are required to completely melt the basalt, but there are some substitute materials available at various locations that are potentially easier to melt.  Prior to use as structural materials, exhaustive testing and manufacturing process refinement will be required to assure mechanical properties.  There appears to be no directly comparable analogs available on Earth, but simulant materials can still be devised using analysis of data from our probes.  This is an engineering project unto itself.

#17 Re: Not So Free Chat » Cost-Effective Credible National Defense » 2026-02-05 23:14:24

Terraformer,

The Proper Role of Turbine Powered Military Aviation Assets
There's a militarily justifiable argument for launching stealthy turbine powered cruise missiles to attack the enemy's network of integrated air defense system sensors and to destroy their tactical fighter jets on the ground.  After that work is done, all further work should be accomplished using dramatically more cost-effective piston engine aircraft.

What makes a military aviation asset "modern"?
If we had a time machine and could send A-1 Skyraiders back to Viet Nam, re-equipped with the radar from the XQ-58A (a Super Hornet equivalent radar that only weighs 100lbs), an ample supply of AIM-9X and AIM-120D missiles, and tasked them with wiping out all American and North Vietnamese aircraft flying over Viet Nam, then within a month or two the only aircraft to be found in the skies over Viet Nam would be A-1s.  I don't care if every American and Vietnamese pilot was a Top Gun valedictorian.  There is only one possible result.  Modern military aircraft aren't "modern" on the basis of engine type or cruising speeds.  Their avionics, sensors, and weapons are what make them "modern" (and lethal).  The speed is nice to have, but there are vanishingly few opportunities to exploit it to any significant degree.

Pure Speed vs Unsustainable Fuel Burn Rates, Cost Unimportant
During the actual Viet Nam War, not one American plane designed to achieve Mach 2 or faster, ever hit Mach 1.4.  During 10 years of fighting, the highest achieved speed during a combat mission was Mach 1.3.  The reason was quite simple.  From Mach 0.95 to about Mach 3, the rise in aerodynamic drag is so sharp that your fuel burn rate increases so fast that your effective combat radius drops to less than 150 miles or so.  At lower altitudes you can burn through all internal and external fuel in minutes.  That's why every F-4 over Viet Nam was equipped with at least 2X 370 gallon wing tanks, and usually a centerline 600 gallon external tank as well.

Presume you came screaming in on the deck in your Phabulous Phantom, full 'burner, "flying under the radar", such as it were.

Let's do some fighter pilot math to illustrate how fast you'll run out of fuel:
While the example used here is America's Cold War Era "heavy fighter", the F-4E Phantom II, it's applicable to essentially every turbojet and turbofan engine powered fighter type aircraft ever made.

12,961lbs of internal fuel
5,032lbs for both 370 gallon wing tanks
4,080lbs for the 600 gallon centerline tank

You have 22,073lbs of total onboard fuel for your combat configured tactical fighter.

17,845lbf of thrust per GE J79 engine in full afterburner, so 35,690lbf from both engines
35,690lbf * 1.965lbs/lbf/hr (TSFC) = 70,130.85lbs of fuel burned per hour
70,130.85lbs / 60 minutes = 1,168.8475lbs of fuel burned per minute
22,073lbs / 1,168.8475lbs/min = 18.88 minutes

You're out of fuel in less than 20 minutes.  You can meaningfully extend your time-of-flight by flying at 30,000ft vs sea level, but the additional flight time you get is less than you'd think.  Flying at high altitudes in a non-stealthy aircraft also comes with significant tradeoffs in a combat zone.

A totally clean F-4 with no external anything (no fuel tanks, ordnance, or even pylons) could achieve 900mph at sea level.  If you're carrying anything at all, especially those giant external fuel tanks, then you will never hit 900mph, but let's pretend to illustrate how utterly ridiculous its Mach 2.2 "top speed" truly is.

900mph = 15 miles per minute
15 miles per minute * 18.88 minutes = 283.2 miles

That's exactly how far your F-4 can travel at sea level in afterburner before it's completely out of fuel.  You'd be lucky to achieve 200 miles if you had anything at all hung off the wings, especially those giant drag-inducing external fuel tanks.  Regardless, you're going to have a very short flight if you stay in burner for very long.

Let's briefly pretend our Phantom was re-engined with very modern GE F414 engines, so 44,000lbf for both engines.
44,000lbf * 1.85lbs/lbf/hr (TSFC) = 81,400lbs of fuel burned per hour
81,400lbs / 60 minutes = 1,356.6667lbs of fuel burned per minute
22,073lbs / 1.356.6667 = 16.27 minutes

That means you're out of fuel even faster by using modern afterburning turbofan vs turbojet tactical fighter jet engines.  Yes, you clearly get more thrust at all power settings and even low-bypass fighter jet turbofans burn a bit less fuel than turbojets, but at the end of the day making more thrust means burning more fuel, period.  End of story.  There never was any other story.

The Irrelevance of "Supercruise" to Air Combat
The F-22 has a meaningfully higher thrust-to-weight ratio than the F-4, so it can actually fly faster than Mach 1 without using afterburner, but that doesn't mean its fuel load lasts significantly longer when you try to "max out" flight speed at mil power or burner, because F-119s are still very thirsty engines which only generate a lot more thrust by burning a lot more fuel.  TSFCs in afterburner for the F414 (a modern turbofan representing a J79-sized engine equivalent) are 1.85lbs/lbf/hr vs 1.965lbs/lbf/hr for "old smokey" (J79).  Even without going into burner, J79 mil power TSFC was 0.81lbs/lbf/hr vs 0.84lbs/lbf/hr for the F414.  That means fuel consumption to make more power is worse, not better.  The primary benefit to the F414 is that you get as much mil power as a J79 produces in full burner, in an engine that weighs 2/3rds as much as the J79.  At no throttle setting does a F414 actually burn less fuel than the J79, and the J79 was a gas guzzler.

If you try to fly just as fast as you can, then you still don't get much more air time, even if the F414 would allow the F-4 to "supercruise" above Mach 1 like the F-22.  Older engines like the J79 also frequently had "burner time limits" of 15 minutes or so, but let's be completely honest with ourselves here, you're not going to fly much farther after 15 minutes in burner anyway.  If you spend any significant time in burner or even at mil power, then you'd better have a tanker directly in front of you or a suitable landing spot picked out.

The Yankee Station Example: Closer to "The Action" than any Modern Forward Air Base
Yankee Station was located approximately 100 miles off the coast of Viet Nam, so 100 miles to "feet dry", and then another 100 miles back to the boat.

Do you plan on making it back to the boat after a mission that takes you 100+ miles inland?

If so, then you're going to be really stingy with the afterburner, and likely have second thoughts about moving the throttle up to the mil power setting after climb-out.  You definitely won't want to "get low" unless forced to do so.  You'll want to stay between 25,000 and 35,000ft whenever possible.  Most of the time you're going to cruise around at 500mph in combat configuration, because that's what you must do to conserve enough gas to fight someone or evade missiles if you have to, and still make it back to Yankee Station.  Best maneuvering speed in the F-4 is also around 500mph.  By the time you're moving at Mach 1, an Iowa class battleship moving at 30 knots has a tighter turn radius than the F-4.  F-4s moving at 500mph could turn inside SA-2 missiles fired at them.  F-4s moving at Mach 1 couldn't turn inside of a ZIP code.

The Multi-Billion Dollar Question
Are we starting to understand why nobody ever went faster than Mach 1.3 during the entire Viet Nam War, despite the fact that we flew tens of thousands of sorties in Mach 2 capable tactical fighters like the F-4, F-8, F-105, and F-111?

Every time I hear someone tell me about how fast their fighter jet is, relative to someone else's fighter jet, my eyes roll harder than the A-4 with its rate limiter removed.

Even in "Fantasy Land", Speed Still Kills Life-Saving Evasive Maneuvering
If you were dropped into the cockpit of a combat jet so fuel efficient that you could economically fly faster than Mach 1, if you don't slow down in a hurry after someone launches a missile at you, you're probably going to D-I-E.  You can pull hard enough to rip the wings off, but when you're flying much faster than 600mph (well below Mach 1), you still can't turn inside of an 80g capable heat seeker like the AIM-9X.  This best maneuvering speed limit is dictated by both flight physics for a 9g capable combat jet and human physiology.  Highly trained and conditioned humans can withstand 10g for very short periods of time, but not much more than that, and nearly all high time fighter pilots who routinely perform such maneuvers end up with severe spinal injuries later in life.

Max power output for a combat jet is therefore reserved for 3 events:
1. Short field takeoffs
2. Rapidly ascending to cruising altitude
3. Recovering energy (speed) following hard maneuvering

Throw a Nickel on the Grass
In fighter pilot training, they teach you to do the fuel math in your head, because if you can't then you're probably not making it home.  Yes, modern fighter jets have fuel totalizers to do the math for you.  If that nifty gadget ever breaks, then what?  I trust my fuel flow rate meter and my ability to do math in my head.  When the fuel totalizer gadget works, it's great.  If not, I'm still not going to have my mother read my obituary because I can't do basic math.  You can think of flight in a modern combat jet as "minutes of life remaining before you run out of fuel, crash, and die", because that is very close to the truth.

Parting Thoughts as to Why Speed Alone isn't a "Determining Factor"
Yes, I absolutely did have to spill that much ink to explain to a non-pilot why the impressive "paper speeds" of fighter jets aren't all that impressive to anyone who actually uses aircraft as weapons.  You are not going to chase down an enemy bomber 500 miles away, which has 10X more fuel onboard than your fighter jet, simply because you're in a Mach 2.5 capable fighter jet, or any similar cockamamie nonsense.  They're either coming to you, in which case you don't need to chase them down, or you're going to launch your own cruise missiles at their air base, because then you still don't need to chase them down.  That is how real world air intercept and attack works.  You send missiles after enemy aircraft, not fighter jets.  The fighter jet is a mobile launch platform.

I think that horse is now well and truly "dead", although one can never be too sure.

Military Aircraft Applications for Modern Automotive Engines
Now let's talk about modern automotive piston engines, which are approximately twice as fuel efficient as a tactical fighter's turbojet or low-bypass turbofan engines across a much wider power output range, while still delivering enough power to "cruise" between 400 and 500mph at altitude, although 350mph is a better cruising speed for fuel economy, and quite similar to the actual cruising speed of a combat loaded A-10.  For comparison, the V-22 Osprey tops out at 350mph and the A-1 Skyraider's top speed was 325mph.

Modern Big Block Automotive Engines as Military Aircraft Engines
Modern so-called "big block" pushrod V8 automotive engines with electronic fuel injection and electronic ignition can deliver 1,000hp, naturally aspirated.  When equipped with a modern supercharger and intercooler located atop the lifter valley, they can continuously deliver 800hp.  RPM kills piston engines, primarily because the pistons come apart.  For extended duration piston life, 4,000fpm is about as fast as you want the piston to move an Aluminum piston.  The most modern high performance heavy duty diesel truck pistons are high strength steel forgings, rather than Aluminum forgings, and do not have the same piston speed limitations.  That said, for a spark-ignited big block, if you keep the RPM to about 4,500 or less, then the engine can run continuously, even using forged Aluminum pistons.

Big Block Definition
I define "big blocks" as V8s that can be configured to total displacement of over 500 cubic inches.  Chrysler, Ford, and General Motors all made "big block" V8 engines.  Ford and GM still offer updated versions of these block designs.  Modern big blocks, whether factory-built or aftermarket, are substantially stronger than the blocks that rolled off the assembly lines in Detroit during America's "muscle car" era.

With a 4.5 inch bore and 4.5 inch stroke, you have a 572 cubic inch V8 engine, a so-called "square" (bore and stroke are the same) engine.  That's a good configuration for fairly high-RPM operation.  Over-square engines (bore larger than stroke) are better for higher-RPM operation, common in racing applications.  Under-square engines (stroke longer than bore diameter), are better for lower-RPM operation, which is why nearly all diesels are under-square designs.

Hot Rod Magazine:
572-Inch Blown Big-Block Chevy Engine Makes 1,013 HP on the Dyno!

Notice from the dyno chart that the engine is making 1,000hp at 6,000rpm, and 800hp at 4,400rpm.

The engine in question has 8:1 compression and runs on 91 Octane motor gasoline using carbs, so no special AVGAS containing toxic Tetra-Ethyl-Lead is required.  Removing TEL from the fuel greatly reduces spark plug fouling and doesn't plate-out on valve seats.  Single vs dual plug ignition is acceptable.  Larger bore engines like the Merlin engine, as well as the slightly newer air-cooled engines from Continental and Lycoming, use dual plugs in part because their bores are so large that the flame front would take longer to reach across the bore.  This has not been an issue for American big block V8s.

The blower configuration used on the newer LS series engines, as found in the Cadillac V series and Corvette, can deliver more boost at lower temperatures, from far less blower displacement than the monster blower shown on the engine from the Hot Rod Magazine article.  Harrop's TVS2650 blower can deliver up to 1,200hp on a big block.  An EFI / EI motor could run 9:1 compression on 93 Octane motor gasoline, so the RPM of the engine could then be lowered to something very similar to the operating RPM range of the geared Continentals and Lycomings, which have even longer strokes.  At that point, the big block is operating like a "real aircraft engine" (the air-cooled magneto-fired dinosaurs that Continental and Lycoming still produce).

Piston Tech, The Real Power Limiter
2618 is the Aluminum alloy of choice, which hasn't changed since it was first used for Merlin engine pistons by Rolls-Royce during WWII.  The best steels for this application produce pistons that are very slightly lighter than 2618 for equal strength at room temperature, but much better strength than any Aluminum alloy at max operating temperature.  Delivering enough splash lubrication to the bottom of the steel piston for adequate cooling is the only issue.  Steel pistons require more cooling oil than Aluminum.  Ceramic thermal barrier coatings on the piston crown help reflect heat back into the combustion chamber.  This sort of tech simply didn't exist when the Merlin and Meteor engines were being developed by Rolls-Royce.  For high-boost engines, thermal barrier coatings are piston savers.  Modern motor oils that can completely remove Carbon deposits from piston ring lands have only existed for the past 10 years or so.

WWII Merlin / Meteor Engine Comparison
The 27 liter Rolls-Royce Meteor tank engine, effectively a Merlin without the supercharger, had a dry weight of 1,841lbs and a power output of made about 550-810hp between 2,600 and 2,800rpm.  The 572 Big Block Chevy with an Iron block and cylinder heads, plus the supercharger and all accessories, weighs less than half as much as a Meteor, which was not equipped with the two-speed supercharger for high-altitude max effort power output.  What is less obvious from looking at pictures is that even with a gearbox attached, the 572 Chevy is less than half the size of the Meteor and Merlin engines for roughly the same power output without boosting it to the moon the way they did the Merlin to produce 1,750 to 2,000hp.  Merlin engines were famous for lifting heads and in war time use would see as little as 50 hours of operation before tear-down inspection and overhaul of select components.  Modern automotive engines, even when used in aircraft applications, do not require nearly as much maintenance.

General Motors Engine Testing
General Motors is famous for running their LS series modern small block engines for over a month at wide-open throttle as part of their testing process.  This manner of engine operation would cause any type-certificated air-cooled boxer-layout "real aircraft engine" from Continental or Lycoming to self-destruct, which is why max output for takeoff is limited to 5 minutes.  You will typically find this admonishment in the POH (Pilot's Operating Handbook).  A "throttle slam" (idle to max power as fast as you can jam the throttle into the firewall), is a better than average way to shear a crankshaft on a Continental or Lycoming.  Maybe you can do it and get away with it, but if I'm flying the plane we're not doing that.  This practice is accepted as "normal operation" for automotive V8 engines like the big block and small block V8 engines.

PSRU Reduction Gearbox Tech Improvements
Modern gearboxes can benefit from Austempered Ductile Iron gears which have a bit of "give" to them to help absorb the torque pulses from the engine.  CAD-enhanced snouts to absorb thrust loads from the props or prop shafts.  Torsional vibration evaluation and testing, which was a "black art" during WWII, is now something that can be readily evaluated almost entirely within a computer program.  The design of the gearbox casings is also enhanced by CNC machining that can accurately machine Aluminum billets or castings.  Substantial weight reduction relative to WWII era designs, for a given torque and rpm input range, is now possible.

Modern Piston Engine Military Aircraft Roles
All of these relatively new-ish but now exhaustively tested and proven technologies add up to the possibility of 1,000hp modified automotive engines for miniature versions of WWII style fighters / close air support / multi-engine bombers, enhanced with modern composite airframe materials, exceptionally powerful and capable miniaturized radars, and exceptionally precise guided munitions.  WWII era aircraft ended the war with 2,000-ish horsepower engines because every bit of the tech from that era was less than half as capable as modern equivalents.  Modern sensors and guided munitions are most certainly incomparably more advanced.  We have self-guided 3 inch cannon shells now, which have shot down cruise missiles and drones at ranges of over 25 miles, for example.  No such animal existed during WWII.  CLGPs for artillery and tanks were 1970s tech, roughly speaking, but now quite practical / reliable / cost-effective.  Palm-sized imaging sensors that can distinguish between two outwardly identical vehicles were the stuff of fantasy.

WWII bomber raids involved dozens of planes, dropping up to 10,000lbs worth of dumb bombs, because their accuracy was almost nonexistent and their sensors were barely adequate to find something resembling the target.  A modernized 4 piston engine bomber equivalent would only need to launch 1 or 2 JSOW glide bombs or cruise missiles from a safe distance to inflict similar damage.  It wouldn't carry 4 to 6 gunners, even if it was equipped with gun turrets for self-defense.  Most likely, a tail turret with 2 to 4 rear-firing Peregrine missiles would be sufficient discourage pursuit.

For "gunship" missions we could replace the bombs or cruise missiles with a 50mm XM913 cannon turret or 40mm CTAS turret that the British use.  The APFSDS rounds fired from the 40 or 50mm would go right through a MBT's turret, and possibly exit through the bottom of the vehicle.  MBT turret top and hull bottom armor are very minimal.  It'll stop 20mm most of the time.  Armored vehicles engaged this way are very dead, for minimal cost.  If that's too close for comfort, then it could also carry some Brimstone or Hellfire or Griffin missiles to plink at enemy vehicles from modest standoff ranges.  Anduril is now making Brimstone / Hellfire weight and cost class miniature cruise missiles that can be fired at targets from 100+ miles away.  That would put a low altitude piston engine "gunship" / "bomber" below the radar horizon, which means any effective defense against them would virtually require air assets.  If the enemy has no IADS, then these are low-risk missions that don't require enormously expensive turbine powered gunships.

Even if this 4 engine bomber / gunship was "lost" in the fight, the weapons it's carrying are probably worth more than the plane itself.  Aircrew are always expensive to lose, but a modern take on the WWII 4-engine strategic bomber won't risk losing 10 aircrew per aircraft.  It will have at least 1 and possibly 2 crew members for most missions.  We could have 1 human pilot and 9 Optimus robots if we decided that we absolutely had to replicate every last detail of the WWII model by assigning 10 aircrew per bomber, but even that doesn't make much sense these days.

When we can afford to put several squadrons worth of planes in the sky for every tactical fighter jet our enemies field, with better sensors and weapons, they're going to get massacred.  Yes, we will lose some of these lower-capability planes in the process, and that's unfortunate.  The difference will be that when all the shooting is over with, since we spent more of our money on better sensors and weapons instead of engines and heavier airframes, our planes will be the only planes still flying, because that's how attritional warfare works.  We can afford to "eat" the losses, as painful as they may be.  Our enemies won't be able to produce enough tactical fighter jets and well-trained pilots to offset their losses.  We can "spam" tens of thousands of these things at our enemies, and eventually most of them won't even have human crew members aboard, only Optimus robots.

Suppose there was a surprise cruise and ballistic missile attack on one of our forward air bases.  Do you want to lose 4 automotive engines and a bit of fiberglass, or an $85M F-35 that we only produce at the rate of 156 per year?

Think about how much money you're willing to risk by placing so much of it in so few tactical fighter jet "baskets".  The US military currently has about 12,000 total aircraft across all types.  Every nation involved in WWII typically made more aircraft of a single type than our entire aviation asset inventory.  The US lost about 10,000 aircraft during the Viet Nam War, mostly rotary wing assets, but also a very significant number of tactical fighters.  That would be an unrecoverable loss with today's turbine powered military aircraft costs.  In WWII, we would call such losses "a bad quarter".  Quantity still has a quality of its own.

#18 Re: Not So Free Chat » Politics » 2026-02-05 12:21:15

RobertDyck,

We've been over this before.  Renee Good and Alex Pretti decided to follow federal law enforcement officers around Minneapolis and physically attack them while they were in the process of arresting people who had warrants for their arrest.

If Alex Pretti had continued working at his hospital like any other ICU nurse, then he'd still be alive today.  If Renee Good did not drive 50 miles away from where she lived and her kids went to school to use her vehicle as a weapon against law enforcement officers, then she'd still be alive today.

Being a pasty white leftist activist is not a shield against consequences if you chase after and assault or attempt to assault law enforcement officers.  You do not actually receive any special privileges because you think you are a special person.  I'm pleased that these lunatics have finally learned that they don't have any "white privilege", and that people with darker skin tones who were shot by the Police has always been about their behavior towards the Police, not their skin color, but that was still a pointless way to die.

If you, as an American citizen, decide to follow the Police around and physically assault them while they're doing their jobs, then you are also subject to arrest.  If you further decide to resist arrest and use or attempt to use lethal weapons against the Police, which both Renee Good and Alex Pretti decided to do, then the Police may then decide to use lethal weapons against you.  The Police are not obligated to wait until you actually murder one of them before they use lethal force to subdue you.

You can avoid all of that pointless violence by not chasing after and assaulting law enforcement officers.  If they tell you that you're under arrest, it's not a debate.  You can choose to surrender, whereupon they will calmly and professionally take you back to their station for questioning, or they will choose to start using force until you either surrender or stop resisting arrest.  Those are your only choices unless you can muster enough force to kill every law enforcement officer in the county.  If you instead choose to contest the matter in court before a judge and jury of your peers, then you have a much much better chance of finding a sympathetic ear there than you do fighting in the streets with the Police.

Have there been people who were wronged by the Police?

Absolutely.  Wearing the uniform doesn't mean you're above reproach.  No thinking person would ever believe that.

Are they ever going to receive true justice by attempting to wrong other Police who didn't wrong them?

Never.  That's not how the entire concept of justice works.

For all those "I can do whatever I want" type people, who are typically leftists but more generally anyone who grew up without a father figure present during their childhood, my answer to them is, "No, you can't and no, you won't."  If you never learned this as a child, then that's a pity, but armed men wearing uniforms will teach you the hard way when you refuse to learn the easy way.  You get to do whatever you want when you are completely alone on your own deserted island, because the only person your behavior affects is you.  Any time there are two or more people present, we establish rules for acceptable treatment of others.  After we debate what the rules should be, we then follow the rules, or there are consequences.  We grant authority to specially trained armed men to enforce the rules because if there is no enforcement of society's rules then there is no society.

If you think American society is somehow "uniquely bad", then you are free to leave it at any time and go literally anywhere else in the world.

Last March a Canadian actress was arrested, held for 12 days. She had a work visa, but ICE decided to invalidate it. ICE claimed it had been invalidated before her work trip to Mexico to film a scene, but nobody bothered to tell her. I don't believe that, they chose to arrest her even though she had a valid work visa, and invalidated the visa after the fact.

If they released her, then why is it not obvious that ICE or some other adjacent federal agency within our federal government made a mistake, and then corrected that mistake by releasing her?

If you're still obsessed over illegal migrants.

I think you're obsessed with the fact that the federal government has reverted back to enforcing immigration laws.  You never said one word about this when President Obama was in charge and ICE was doing the exact same thing it's doing right now.  Either tell me why it was no big deal when ICE was enforcing immigration laws under President Obama, or admit that you can't.

In 1986, Ronald Regan solved all immigration issues.

He did, huh?  Lol!  All evidence to the contrary notwithstanding, right?

But employers pressured Congress to remove all penalties for violating the rules.

In the very next sentence, it sounds like you're telling me that Ronald Reagan "didn't solve" all immigration issues.

Employers want workers to be illegal, so they can pay them below minimum wage, and work them in unsafe, unlawful conditions. This is what rich spoiled brats who control Congress want.

It sounds like you're complaining to me about the fact that President Trump is separating rich and entitled people from their would-be slaves, exactly as President Lincoln did during the Civil War.  Presidents Lincoln and Trump are both Republicans, and Republicans don't allow slave ownership.  The Democrats were the political party supporting slave ownership during the Civil War as well.  Times change, but the morally reprehensible actions of the Democrats never do.  Funny that, if only it was funny.  You have all of the puzzle pieces and a picture of the completed puzzle, but you refuse to put the pieces where they go because you don't like what the finished picture shows.

Don't blame the migrant workers; they're just doing what was expected of them.

I don't blame the illegals for how rich entitled Democrats want to exploit other people, but to end the Democrats' latest attempt at exploiting them, they need to go back to where they came from and re-enter America the legal way so they cannot be used by Democrats as pawns in their stupid self-serving slavery game.

And as for Minnesota: do you seriously believe there are any illegal immigrants there? He's harassing that state because they voted Democrat.

Democrats scattered illegals all throughout the interior of America and used many tens of billions of tax dollars to do it.  Minneapolis, Minnesota is unique amongst Democrat-run cities in that their state and local government decided they would then fight federal law enforcement over enforcement of our immigration laws.  This was done not because the Democrats care about the illegals, but because a local nobody exposed a massive fraud scheme, amounting to about ten billion dollars, that both Walz (Democrat Governor of Minnesota) and Frey (Democrat Mayor of Minneapolis) were complicit in.  When President Trump's administration later announced it would investigate the Democrats' latest fraud, rather than accept the loss of their fraud money and start behaving like decent human beings towards their own fellow Americans, Democrats in Minnesota found yet another way to weaponize their corruption against their political enemies.  After all of their lunatic idiocy over being cut off from their supply of fraud money from the federal government, Walz and Frey have already flipped, and are now cooperating with ICE and CBP.

ICE is "harassing" every state in America, irrespective of who they voted for.  Here in Texas we just call their harassment "immigration enforcement".  Our local and state governments cooperate with federal law enforcement agencies, rather than using our state's tax money to fund a network of home-grown terrorist cells who roam around looking for federal law enforcement officers to assault.  You are free to believe otherwise, but it won't change reality.

I am thoroughly impressed by your ability to ignore cause-and-effect reasoning and what our actual immigration laws state, but you have thus far failed to present any legally or logically reasonable arguments pertaining to why ICE should not be allowed to enforce immigration laws or why leftists should be allowed to assault federal law enforcement officers who are performing their lawful duties.

If you can formulate any legally and logically consistent arguments as to why federal law enforcement should not be allowed to enforce existing federal immigration laws, then I'm open to discussing them.  If this is not about our laws, and is instead being driven by your emotions or beliefs about someone or something you despise, then there's nothing to discuss because nobody can invalidate your feelings.  Your feelings are very real to you, but that doesn't mean they're representative of objective reality, only how you feel about it.  I'll continue to refute every non-argument and false premise argument presented.

#19 Re: Not So Free Chat » Politics » 2026-02-04 19:27:34

RobertDyck,

Just because you said it, does not make it reality. That's not proof, it's not data.

I'm not making personal claims here.  I provided a link to findings of studies and reports compiled on illegal aliens, criminality, and reporting of crimes.  By your argument, which is fallacious, a census does not count as "proof" of anything, either, because it has not been adjudicated by a trier-of-fact (court of law), except that it is, and gets used as the basis for all sorts of public services and government representation.

Your claim that criminals do not report crimes?

When someone knows they are guilty of a crime, they tend not to report other crimes against them when doing so would result in legal action taken against them as well.

That can be said for US-born citizens as well.

You are correct, sir!

People who are already criminals tend not to report crimes against them.  We have criminals on tape committing crimes against other prisoners while in our prisons system, yet the victim who a crime was perpetrated against, by another criminal, refuses to acknowledge that a crime even took place, much less testify against the other criminal, even when doing so leads to a reduced sentence.

Most citizens are not criminals, but you fail to take into account crimes committed by US-born citizens.

Since we already have plenty of citizens who are criminals, can you tell me why we need to add to the total number of criminals in America by importing foreign nationals, more than a few of whom are also hardened criminals themselves, without so much as bothering to check IDs or run a background check at the border?

That was what we did under President Biden.  Even when they knew the illegal alien in question was a convicted felon, they still released them into the interior of the United States.  That seems utterly insane to me, but that's exactly what they did.  The law is crystal clear about what should've been done, but Democrats don't seem to accept that laws apply to them as well as everyone else.  They think they get to pick-and-choose which laws to enforce if they win an election.  That was never how the law is supposed to work.  Now we're back to enforcing the law again.  That means all the known felons who were convicted of major crimes before entry, or suspected of such crimes after entry into the United States, are getting rounded up and imprisoned or deported.  They never should've been allowed to roam free in America in the first place.

That was the thrust of my argument, which you ignore because you're more fixated on "being right" than "actually being compassionate".

This demonstrates simply that you are prejudiced. You assume all immigrants are illegal, and you assume all immigrants are criminals. You won't let reality sway your prejudice.

I assume that all illegal aliens are criminals, because United Sates Code says it's illegal to enter into the United States without permission granted by our federal government.  This is a federal felony, and a felony is a crime.  You are free to argue what you think the law should be, but my arguments relate to what the law is, rather than what I wish it was.

Again the point: I was an immigrant. Does this mean you're prejudiced against me too?

If you entered into the United States legally, then you have my support.  I would hope you have the support of all Americans.  Through fidelity to our laws, you have the right to expect and should receive all the protections of law afforded to any other American citizen.

If you entered the United States illegally, then you should go back to wherever you came from and submit an application to become an American citizen if you wish to live here.  If your only crime was entering the United States illegally, both Democrat and Republican administrations have maintained that they will continue to impartially evaluate and grant re-entrance back into the United States and citizenship.  To wit, this interpretation of immigration law and its application has not changed for a very long time.

The United States has the most generous immigration policy of any nation because we are a nation of immigrants.  The desire to come to America, which we encourage and support, does not mean your first act on American soil should be breaking our immigration laws.

I've been to Canada twice in my life.  In both cases I showed my passport to the Canadian authorities and waited patiently to be granted entry.  At no time did I ever ignore Canadian immigration laws simply because I wanted to enter Canada and couldn't be bothered with obtaining permission from the Canadian government.

I've been to Mexico once in my life, for work.  Same deal.  I presented my passport, answered all of their questions about why I came to Mexico, and once they were satisfied with my answers I was sent on my way.

If Canada or Mexico refused to grant entry to me, then I would've gone back the way I came- no arguments, no threats, no attempts to "sneak in" away from a legal entry point in the dead of night.  The reason for that is quite simple.  I respect the people of Canada and Mexico enough to respect their government's decision about whether or not I am permitted to be in their country as an invited guest.  As an American, I think I have the right to expect the same thing of people who choose to come to America.  That is completely fair and in no way prejudiced against anyone.

Calliban,

Robert, the statistics you referenced are questionable to say the least.  In the UK, immigrants are far more likely to commit crimes.

If you are expecting an honest intellectual interaction with leftists who use personal bias filtering logic and faulty methods to gather and evaluate data to support their beliefs about the data, then you are going to be very disappointed with them.

Leftists don't typically apply much point-vs-counter-point reasoning to what they believe, they simply look for anything which supports their beliefs whilst ignoring all other "minor details" which frequently add up to a "major disconnect" between snippets of supporting data and totality of circumstances, which always presents the clearest picture of objective reality.

I'll provide a more concrete example from my personal life:

While we lived in a house in a gated subdivision a few miles from where we currently live, someone broke into my wife's Cadillac XT5, rummaged through the car for a short while, found nothing to steal, and then hopped back over the fence.  We have this person on video and the Police woman who showed up actually took fingerprints and DNA off my wife's XT5.  This guy did thousands of dollars worth of damage, but ultimately took nothing because we don't keep anything of value in our vehicles.

My nextdoor neighbor found out about it when she saw the Police cruiser in our driveway, and then she asked to come over to watch the video.  She was a black woman and a "proud Texas Democrat" (this is how she "self-identifies"), a first generation legal immigrant like my wife, though from our various interactions with her and her family, not a radical leftist, thankfully.  Her grandson was friends with my daughter for awhile, and they played together when his mother or grandmother brought him over, but ultimately he went to a private school while we've always had our children in public schools, so they drifted apart.  I counted her husband as a friend of mine, and he was previously in the military, as I was.  He worked on radios and some early computer equipment, just as I did, but for the US Army, during the Viet Nam War.  I don't think he actually went to Viet Nam, though.  He was stationed in Germany.  He's since died (not from COVID), but his widow still lives there.

Her first questions to me, before even watching the video with my wife, were:
Q1. Is he black?
Q2. You're a Republican.  You have guns.  Why didn't you shoot him?

A1. He did have a darker skin tone, but it ultimately turned out that he was NOT black.  He wasn't even an American.  His fingerprints weren't even in the system because he was an illegal alien.  He was later caught while trying to steal a car more than a year after that, which I only learned when the Police woman who took his prints and filed our report relayed that update to me when she saw me working in our yard over a year later.  He was tried in court and was deported, but the crime he was convicted of did NOT include his break-in of my wife's vehicle, despite the fingerprint and DNA evidence collected at the scene.  That means he committed at least 2 separate felony crimes that I know of, but the crime against us did not "count" towards the total.  Unfortunately for me, and possibly the second victim, that didn't mean I wasn't still required to pay for the damages he caused.  It would be completely absurd to think he committed zero crimes between the time he broke into my wife's vehicle and his arrest.  It would be equally absurd to think my wife's vehicle was the very first one he ever broke into.

A2. I didn't "shoot him" because this happened around 4AM in the morning while I was asleep because I had to work the next day like every other law abiding citizen, and he never tried to break into our house.  He didn't do anything to put my family in danger, so he was never worth the cost of the ammo, much less the legal fees for the subsequent court case.  You can legally shoot someone who is committing a major crime here in Texas, but you cannot avoid the (rightful and lawful, IMO) trier-of-fact scrutiny following the decision to do so.  I don't go out looking for trouble, either, because I'm not a criminal and have no desire to interact with criminals if there's any choice in the matter.  I would much prefer to have the Police do what they're tasked with doing.

What did I learn from that interaction and others with my Democrat neighbor?

She was so certain that the perpetrator belonged to a specific racial group that she ignored other possibilities.

Why did she think that?

It was her personally prejudiced beliefs, plain and simple.  In a follow-on conversation with her weeks later, she admitted this to me.  She was previously the victim of a home invasion, and the perpetrator was a black man.  She made the logical leap to "the perpetrator of this crime must also be black because someone who was black perpetrated a crime against me" vs "let's watch the video so we know who this is if we seem him again and then let the Police and courts do their job".  After the courtroom results, then we can make some semi-informed judgements about what actually happened.  Leftists, and more than a few rightists, really don't like this "wait and see" method of evaluating reality.  Even after my neighbor saw the video, she still insisted that he was black.  I was much "less sure" that her assumption was correct, because he looked a lot like various people I've seen from South American countries.  I can't remember if he was identified as being from El Salvador or Guatemala (I don't have "total recall" of all details 9 years after the fact), but I do remember that he was deported after his trial.  For all I know, he came right back due to the refusal of President Biden's administration to enforce our immigration laws.  I happen to think two major crimes are enough.  I also think both crimes should count towards the total, not simply the one he was convicted of.  I further think he would not be in America if we were enforcing our immigration laws.  I can only wonder about how many crimes he actually committed because our government decided protecting their own people was not their first and most important duty.

Democrats, and leftists especially, tend to substitute their prejudiced personal beliefs and learned biases for a "totality of circumstances" view of objective reality.  There are more than a few Republicans I've met who hold similar views for what I presume to be similar reasons, but I also find they are at least willing to consider alternative explanations that disagree with the assumptions they've made because most of them are still more interested in "what is true" vs "my beliefs were validated".  Regardless, people who do this tend to make "big picture"-deficient assumptions and worse decisions as a result.  Sometimes it works in their favor, but most of the time it leaves the person who holds such beliefs with a very contorted perception of reality.  If you ever provide a perfectly valid counter-point or pertinent bit of data that doesn't support their belief system, they don't even consider altering their beliefs accordingly, they immediately try to find some way to discredit the new information presented to them.  It's a "bias-based information rejection" vs "information assimilation" belief system.  It's quite common, but a terrible way to both evaluate new information and make major decisions.

What does all of this "add up to" as it relates to my interactions with leftists?

Whether my interaction was in-person or through back-and-forth over the internet, the majority of leftists care more about finding ways to feel morally or intellectually superior to others by having their belief system validated than they do about whether or not they're actually helping anyone but themselves.  This system of interacting with the world produces horrific results when applied to public policy.

The illiegal migrants flooding into the US are the same sort of people.  How do you account for the divergence between UK statistics and the stats you referenced?

There is nothing "uniquely bad" about muslims, relative to any other immigrant population.  That said, people who are perfectly willing to knowingly break the law to obtain something they want from someone else are most likely to repeat that pattern of behavior because doing so worked for them in the past.  Why would they deviate from the behavior that obtained what they wanted?  This sort of information may be obtained by attending Psychology 101 in college.

None of the adult muslim immigrants who enter the UK illegally are "unaware" that what they are doing is illegal, because it's also illegal in their nation of origin, as well as all other nations.  There are no nations on Earth where it is "legal" to rape, rob, or murder someone, either.  That means certain behaviors are universally adjudicated as "criminal behaviors", and therefore do not change merely because you entered into another nation.  Similarly, there are no nations on Earth where it is legal to cross national borders without permission from their respective governments.  You may be able to "get away with it" in certain places where there is little to no effective law enforcement present, but those examples are universally crimes that carry significant prison sentences, if not capital punishment as well in the case of rape and murder.

Consistent enforcement of laws that does not make allowances for any superficial physical characteristics is the only valid way to maintain a civil society.  Any other policy will result in an increasingly uncivil society that denigrates its own citizens and foreigners alike.  This should not be what we advocate for nor permit to continue by electing people who value consistency over appearances and emotions.  There cannot be special classes of people subject to special application of the law in a civil society.

RobertDyck,

There is nothing funny about this. You hare lying. When faced with hard statistics that prove your assertions are wrong, you just lie, you claim the statistics are wrong.

Your "hard statistics" have a gaping hole in them.  Crimes against illegal aliens committed by other illegal aliens ARE NOT REPORTED, more often than not, and the illegal aliens already told you why they do not report crimes against them.

If you want to counter anything I posted, then provide proof. I posted a reference, a source with hard statistics. The result demonstrates your assertion is absolute bullshit.

You demonstrated how you attempt to find data to fit your narrative, but when the the data doesn't reflect reality, you instead choose to ignore reality.

Since you decided to focus on Texas and motor vehicle crimes, specifically, let's look at Texas.

Let's examine how ridiculous your claim about Texas traffic crimes for illegals vs citizens truly is:
Dangerous and Deadly Vehicle Pursuits under Texas’ Operation Lone Star

According to media reports indicating the pursuits involved vehicles containing migrants, as well as DPS records obtained by Human Rights Watch under state public records laws, in the 29 months between the start of OLS in March 2021 and July 2023, at least 74 people were killed and another 189 injured as the result of 49 pursuits by Texas troopers or local law enforcement, or both, in Operation Lone Star counties. That is a rate of nearly 3 deaths and 7 injuries per month that OLS has been in existence, a significantly higher toll than the nearly 2 deaths per month previously reported by media and civil rights groups, and higher than the toll in other Texas counties over the same period. Of the 5,230 total vehicle pursuits that DPS troopers engaged in across Texas’ 254 counties since March 2021, 3,558 of them, or roughly 68 percent of all pursuits, occurred in the 60 Operation Lone Star counties that represent 13 percent of the state’s population. This means Operation Lone Star county residents are experiencing a disproportionate share of vehicle pursuits across the state.

Human Rights Watch is known to support and advocate for illegal immigration into the United States.  This is merely them here "telling on themselves" by complaining about the uptick in criminal activity associated with the immigration policy they support when Texas law enforcement continues to do its job.

Why are there so many "deadly" motor vehicle pursuits against illegal aliens?

Illegal aliens actually commit crimes at higher rates than the Texas citizens living in those counties, and then when DPS tries to stop them, they run from DPS.  68% of all DPS motor vehicle pursuits in Texas involved illegal aliens running from the Police.  That means illegals represent 2/3rds of all DPS pursuits.  Running from the Police on a public roadway is a crime, a felony at that, and those are the results.

If you want to counter, then you are required to post a source to backup your assertion. If you cannot, then we will conclude that you are wrong.

I already did that.  70% of illegal aliens respondents, who were not worried about their illegal status being used against them, said they do not report crimes to the Police when queried.  Crimes happen most frequently against people who know and interact with each other on a daily basis, across all people in all nations.  This is a fact, not a conjecture.  Illegals living in the US most frequently interact with other illegals.

If that wasn't enough, Human Rights Watch just backed up my assertion with hard data obtained from Texas DPS, and Human Rights Watch supports and advocates for illegal immigration.

Void,

So, even the average "modern" robotic woman treats men horribly?

I guess it wouldn't be a "real" female robot without exhibiting real female behavior.

If you find one that doesn't look like a beached whale and isn't more venomous than a cobra, do let us know.  I always love reading about unicorns.  My brain knows they aren't real, but my heart still loves a good story.

If her robot hitman boyfriend murders you, consider it a reprieve.  You could've spent the rest of your life with someone, or "something", which is miserable and ugly to its core.

SpaceNut,

Ask the AI what yield strength (YS) it's using for the 304L tubing?:

A. room temperature YS
or
B. YS over the mildly cryogenic temperatures found at Korolev crater

The difference matters quite a lot.

RobertDyck,

Aw! Legal immigrants have trouble with traffic, eg speeding tickets. Violent crimes are committed by US-born citizens. So perhaps state troopers need to crack down on US-born citizens in Texas.

I'm sure you think you're being funny, but your behavior indicates how the policies of people who think the way you do encourages victimization of illegals as well.  It's actually repulsive how little regard you have for the lives of the very people you think you're defending.

Most people who are victims of violent crimes are victimized by someone they know and interact with on a daily basis.  Since we're talking about illegals here, that would mean other illegals living in America.  Multiply your stats for the illegals by about a factor of 10 and that's pretty close to reality.  Most of them simply don't report crimes because they don't want to get deported.

If you're an illegal, then you cannot legally obtain a driver's license in the states that follow federal law, and you're definitely not sticking around to file police reports if you run into someone else, so that would be why they have fewer traffic violations.  The actual number should be zero because they shouldn't be able to obtain a driver's license.

Fear and Silence: 2025 Insights from Advocates for Immigrant Survivors

Precise numbers on crimes committed by undocumented immigrants against other undocumented immigrants are not officially tracked, largely because a high percentage of these crimes go unreported to law enforcement. Studies and surveys suggest that undocumented immigrants are often reluctant to report crimes due to fear of deportation, resulting in high rates of unreported victimization, particularly in domestic violence and sexual assault cases.

Based on analysis of crime surveys and reports, here is the available data regarding this issue:

Extensive Underreporting: Researchers estimate that only about 11% of crimes committed against undocumented immigrants are reported to the police.

Fear of Deportation: A 2025 survey of immigrant advocates found that 76% reported their clients feared calling the police due to potential deportation, with many choosing to drop cases.

Victimization by Known Offenders: Undocumented immigrants are more likely to be victimized by someone they know, often another undocumented person, which increases the likelihood of silence due to fear of retribution or fear of legal exposure for both parties.

Underreporting Specific Crimes: Domestic violence, sexual assault, and gang violence are consistently cited as the least reported crimes, with studies indicating that up to two-thirds of these incidents may go unreported in these communities.

Survey Findings vs. Reality: While some analyses of the National Crime Victimization Survey (NCVS) suggest that, generally, non-citizens report crimes at rates similar to native-born citizens, this is often disputed by community-level studies showing deep mistrust of law enforcement among the undocumented population.

Key Factors for Non-Reporting:
Fear of Retaliation: 42% of unreported crime victims surveyed (general population) cited fear of reprisal.

Lack of Trust: 70% of undocumented immigrants in a 2013 study reported they were less likely to contact police, even if victims of a crime.

Fear of Discovery: 30% of undocumented immigrants identified fear of deportation as the primary reason for not reporting crimes.

clark,

@kbd512, you are a dirtbag of the first order. The willingness you demonstrate to rationalize state sanctioned murder based on political belief is appalling and damming of every single person that aligns with you.

This young lady's name was Laken Riley:
Laken-Riley-ht-gmh-240223_1708727427813_hpMain_4.jpg

She never had the chance to become a nurse because she was raped and murdered by the sort of illegal alien criminals those ICE agents were in the process of arresting when Alex Pretti decided to attack them.  Your outrage over her death was conspicuously absent.

A goddamn ICU nurse for the VA, shot unarmed, by poorly trained federal agents, is somehow his fault?

Alex Pretti was armed and he did assault federal law enforcement officers at least twice that we know about.  Is your claim that they were poorly trained based upon any personal knowledge of Police Procedure, or merely anger over the result?  If you repeatedly chase after law enforcement officers and assault them while carrying a gun, your chances of being shot increase exponentially.  Being an ICU nurse for the VA doesn't change that.  Being a Catholic Priest wearing a MAGA hat doesn't change that, either.

You've shown a glimmer of being rationale in the past, talking about your immigrant wife, and being texan in texas.

My immigrant wife couldn't believe ICE didn't shoot Pretti during his first unprovoked attack against their agents.  I'm not sure how being a Texan in Texas makes me more or less "rational", but a lot of your argumentation comes off as very emotional, so I guess I shouldn't expect much logic or reasoning where there likely isn't any.

You've been pro gun on numerous occasions and here we have  a card carrying gun holder shot by the government, but because he disagrees with your politics, well, sh*t, gunning him down was his fault. Seriously.

Being pro-gun doesn't mean I think repeatedly chasing after and assaulting federal agents who were sent to arrest a rapist is an acceptable way to behave.

LT Christopher Dorner was a fellow Navy man.  He was quite clearly a "card-carrying pro-gunner" as well.  Sadly, he also shot seven people who were not initially trying to do anything at all to him.  I don't agree with or condone what he did, either.

Politics has nothing to do with how I feel about what Alex Pretti and Christopher Dorner did to other people.  They ceased to behave like responsible adults when they began behaving like enraged maniacs over whatever perceived injustice they felt they were subjected to, and that's where they lost me.  Both men chose to engage in "street justice" and received "street solutions" in response.  Their treatment of people who did nothing to them is what matters to me, not the fact that they shared one specific value I have.

You're an embarrassment as an American.

From the few times we've interacted, you've engaged in a lot of name-calling, angry outbursts over things that were not even done to you, personally, and uncivil treatment of other forum members.  I'm not embarrassed by you, but I am disappointed by how you treat others who don't share your opinions.
