Tom,

Beautiful!

BUT, Earth radius? Show me it's possible in material strength, pls.

Why go at all over the proven diameters? - up to 5000km wide by using carbon.

Paul Birch.:

The maximum size of conventional rotating space colonies is determined largely by the strength of available
structural materials. The limit is about 250 km radius for quartz, 1000 km for sapphire, and 2500 km for
diamond.

What is the material strength of say Tungsten carbide? It is 15.6 grams per cubic centimeter therefore 15.6 tons per cubic meter. Diamond by contrast is 3.53 grams per cubic cm or 3.53 tons per cubic meter.

Tungstein has a tensile strength of 344 MPa
Carbon nanotubes have been measured to have a tensile strength of 63 gigapascals. But carbon nanotubes have a density of 1.4 grams per cubic centimeter or 1.4 tons per cubic meter. Within the same volume of carbon nanotubes, you could have 11.14 times as much Tungstein carbide. This gives tungstein carbide about 3.833 gigapascals if it has the same cross sections a nanotube cable. Give the Tungsein carbide cable 16.4 times are area cross section as the carbon nanotube cable, and that Tungstein carbide cable will have the same tensile strength as the nanotube cable, this also means a given length of Tungstein carbide cable will have 182.696 times the mass as an equivalent nanotube cable of the same strength, but does the mass of the Tungstein carbide matter? Lets say you wanted a Tungstein carbide cable with 100 times the tensile strength of carbon nanotubes, increase the cross sectional area to  1640 times the cross sectional area of carbon nanotubes, and you would get a tensile strength of 6300 gigapascals, by thickening the Tungstein Carbide cables, you can get as much tensile strength as you want for whatever purpose you want. The trick is not to rotate the Tungstein carbide cables with the rest of the structure. Have you ever heard of Magnetic Levitation?

With magnetic levitation, you could have tungstein carbide cables as thick as you please, and you would magnetically levitate the rotating structure off of the nonrotating tungstein carbide cables, and you make the tungstein carbide cables strong enough to support the rotational weight of the rotating structure. You want to cables as dense as you can get it to create the maximum amount of tensile strength with the minimum amount of wrap around rotational structure. You could put these tungstein carbide cables wherever you need them, they just need a circular path in a vacuum for them not to rotate in as the rest of the structure rotates while wrapped around them. You could have tungstein carbide cables within the walls of the structure to retain atmosphere, you could have them supporting the floors, you could even have them supporting structures above the ground within their own separate evacuated tubes inside the cylinder, say for the purpose of lighting and ceiling panels if you want them. I'm not sure if tungstein would be the best material for this, but I use it as an example, no doubt steel could be used also, it would just require thicker cables. Steel and tungstein is easier to make than carbon nanotubes, so there might be a good reason to use these materials as an alternative to carbon nanotubes.

Easier to terraform the asteroid, with the asteroid, you can have Earth normal simulated gravity A Worldring with a  diameter the size of the Earth, can be rotated once every 90 minutes to produce Earth normal simulated gravity, and just make the walls at either end of the cylinder 300 miles tall and you can hold in atmosphere.

You mean John McCain don't you? Do you know what happened to the Republican Party in the wake of Watergate? Nothing good! Well John McCain is trying to instigate a Watergate on his own party. Well it looks like John McCain rode on Trump's coat tails in 2016 to be reelected to a sixth Term in the US Senate. Has John McCain shown any appreciation for that fact? Nope! He was hoping that Hillary Clinton would win and all the fine Republicans in his state would elect him anyway, maybe splitting the ticket, voting for him and then Hillary, then Hillary could teach John McCain to fetch, roll over, and play dead, and then she could reward him with a bowl of dog food, of perhaps a doggie treat if he acts as a real good "lap dog" for the Democratic Party. In all honesty, why should the Republicans vote for such a fake Republican as John McCain? If they wanted to vote liberal, they could elect a Democrat, John's next election is in 2022, I'm getting a feeling this is going to be his last term in office, I don't think the Arizona Republicans will be played for a sucker one more time.

Senate panel subpoenas Flynn for Russia docs, Comey reportedly requested help for Russia probe days before being fired and with that Trump's decision to fire Comey raises questions in even the republican ranks.... America is witnessing a Constitutional crisis, says leading Democrat...with Trump Keeps Acting Like He Has Something to Hide

So you think that if you search hard enough, you can always find it even if its not there? How much money do you think NASA should spend searching for UFOs that are alien spaceships? How much money should the Federal Government spend on Loch Ness Monster research? These things are not proven to exist, does that mean we should search harder, or redirect our efforts to more productive avenues? The Democrats are using the fact that no evidence was found as a reason to keep on searching, but we can't prove that UFOs are alien spaceships either, does that mean not enough money was spent to investigate these claims. How about paranormal research, should we have a real Ghostbusters? How much money should we spend on quackery?

The official spin from the White House, dutifully repeated by all of President Donald Trump’s Republican enablers, is that Kremlingate is a big nothingburger. Or as White House spokeswoman Sarah Huckabee Sanders said on Fox News Tuesday night after the shocking dismissal of FBI Director James Comey: “I think the bigger point on that is, my gosh Tucker, when are they going to let that go? Unfortunately for the White House, this air of nonchalance is belied by a man who is in a far better position than a deputy press secretary to know what actually transpired during last year’s campaign. To which they all want us to move on...

Seems that the Democrats hated James Comey until Trump decided to get rid of him! Have you seen this interview with Maxine Waters? The Democrats sure do have a tough time explaining themselves. Chuck Schumer was calling for James Comey to resign, until Trump fired him, and now Chuck Schumer is complaining about that! What do you call Chuck's knee jerk opposition to the only President from New York since FDR was last President of the United States? In stead of trying to help his fellow New Yorker to be a memorable President, Chuck Schumer is being an oppositional impediment, thinking only about the perceived good of his party and not of his country or state! Chuck Schumer is not a loyal American, he is a Democrat trying to gain power instead!, It looks like Chuck is facing another reelection in 2022 just like John McCain. If New York Voters only want a Democrat to win and don't care about the results other than that, they can vote for Chuck Schumer in 2022! But personally, I would like to see Chuck get chucked! politics is not a game for the average voter, it is not a sport where they can sit on the sidelines and the result does not affect them except for bragging rights!

So Did AG Sessions Violate His Recusal by Advising on Comey Firing? Legal experts say Sessions may have indeed violated his own recusal standard, though the unusual issue is by no means clear-cut. Sessions, who has said he has had no improper contact with the Russians, concluded after meeting with DOJ ethics lawyers in March "I should not be involved in investigating a campaign I had a role in."

But there is no evidence of wrong doing except for the part where a private American citizen was unmasked.
You know what the standard is, "Innocent until proven guilty!" No Witch Hunts! It is a waste of government resources to pursue improbable and unproven leads. The FBI should not b investigating UFO or Bigfoot, of anything else where their is no evidence, there are people who swear they have seen a UFO, its only that their film was over exposed, or the UFO flew too fast, or the UFO zapped his camera with a ray beam, and that is his excuse for presenting no concrete proof of a UFO sighting. So I say we should treat the Russian connection just as we would a UFO sighting, there is no proof after seven months of investigations, and the FBI's resources are limited, there are murders to investigate, and investing time and money in this political witch hunt is taking away resources from criminal investigations.

Too many Democrats are still hoping for Impeachment as a means of replacing our President, they are not sure about of what to Impeach him for, there are fruitless investigations going on of his ties to the Russians, but it is turning out that it is entirely fiction, and it is making it difficult for the President to attempt to reduce tensions between the US and Russia if the Democrats continue this "witch hunt!" Vladimir Putin has not made it easy for Trump either, with his support of dictators that use chemical weapons, and for th threatening maneuvers of Russian aircraft and ships with respect to US and NATO territory. you have to admit, Putin has not tried very hard to get along with us and live a peaceful existence. Democrats, until recently, we defending Putin's aggressive and imperialistic foreign policy, but they can't really do o now while at the same time accusing Donald Trump of being unduly influenced by the Russians! I bet a lot of Democrats would like to, but they want to attack Trump. Once it is proven that Russian influence I baseless, they'll get back down to defending our hostile enemies and adversaries, finding excuses to justify their every offensive move. But Putin is finding this frustrating as well, the press isn't defending them as much as they used to, because they are too busy attacking Trump, and its hard to do both at the same time.

Which far right do you mean? That of Hitler? I do not think I can be compared to Hitler, and as far as I know, references to "Far Right" usually means Hitler, or Nazi or Fascist, that is far right. Someone like Rush Limbaugh is not a Hitlerian, a Fascist or a Nazi so he does not qualify as Far Right in my book. Are you making up new terms and definitions for old labels by any chance? By your standards, most of th Presidents of the United States would be called "Far Right" because most of them were not socialists!
Most Presidents of the United States were not like Barack Obama.
united-states-president-list-2017.jpg
Here is a example, see the picture above, which ones of these Presidents would you consider to be "Far Right-wingers"? Donald Trump was to the right of which Presidents? I can think of only 2 out of these 45, that would be Jimmy Carter and Barack Obama. I think for instance that Trump's position on immigrants and minorities was more liberal than FDR's. FDR for example interned Japanese-Americans, he presided over  segregated armed forces for example, I don't think Trump has advocated any of that, so I am just saying becareful of who you call a "Far Right Winger" I believe most of the Presidents of the United States would qualify under that definition.

That being said,  he's right about the thread title,  just wrong in what he chooses to post about it.  The perversion of science due to politics comes from "science denial",  which is really discounting scienctific data and facts in favor of preferred political beliefs,  without regard to truth.  There's plenty of this to go around on both sides of the aisle here in the US.

 
Okay, if someone effectively says, the world is going to end because of Global Warming, don't we have a right to be skeptical? Skepticism is part of the Scientific method after all. You have a bunch of liberals that advocate we make drastic changes because of global warming, so what I'm saying is before we make these drastic changes, you have to prove that there is global warming.

In the modern GOP dominated by the minority tea party / freedom caucus / pick-a-name right-wing extremists,

 
I wish it were so, if it were so, the Republican Party would have nominated Ted Cruz instead of Donald Trump, we would have repealed Obamacare within the first 100 days of the new Presidency, it would have been real simple to do, if what you were saying is true, but to not! We have a lot of "mushball moderates" in the Republican Party, people who say they will repeal Obamacare when they are running for election, but then find excuses not to do it once they are elected. A Tea Party dominated Republican PArty would have cut taxes, and would not have looked for new revenue to balance it out. The Tea Party is a Political Party within a party made up mostly of moderate and RINOs, it wouldn't have passed and funded so many of Obama's programs over the past 8 years if it were not! I think, in the future, the Republican Party may split due to lack of competition from the Democrats. It is a two-Party system after all, and if the Democrats can't fill the shoes of that other party, someone else will fill that vacuum.

it has become a touchstone requirement for membership that you deny any human-caused connection to climate change,  irregardless of the facts right in front of your face.  Implementing such beliefs as public policy is quite dangerous,  and certainly wrong. 

This is not the only case on the GOP side,  but is sufficient to make my point. 

The same is true with the Democrats on the false belief that vaccines cause autism.

 

Lets take these two propositions you put forward:
1) Humans cause climate change.
2) Vaccines cause autism.

Why do you automatically assume 1) to be true and 2) to be false? How come for instance, you do not have to prove that vaccines do not cause autism? Then why do you assume that we hve to prove that humans do not cause climate change with a default position that the do. The data collected has been suspect, where you put your thermometers to detect climate change is very important, for instance, if you put them on top of smoke stacks of factories and power plants, you will detect climate change and global warming.

(There are some GOP types who subscribe to this too,  so it's not uniquely Democrat).  The one and only paper that made the autism link claim was completely-discredited and retracted years ago,  yet it is still cited by the vaccine-avoidance crowd.  Multiple studies done since have confirmed there is no such link,  yet this evidence is ignored because it conflicts with the preferred political belief system.  As a result,  there is an outbreaking measles epidemic in Minnesota even as we converse,  because too many skipped vaccination,  and the "herd immunity" has fallen too low.

 
You know science isn't  democracy, you don't prove something to be true by having scientists voting on it, and whoever can get enough scientists to agree to position A is the winner. You know scientists only exist because someone has hired them and pays their salary. So what do you get if you have tobacco companies hire scientists to determine whether cigarette smoke causes lung cancer? If they say it does, they may be out of a job! Just polling scientists is not the scientific method. Most scientists like to keep their jobs, and if they have to lie or fake data to do so, many of them will.

This is also not the only case on the Democrat side,  but it is sufficient to make my point. 

Is not a preventable outbreak of disease not a danger to the body politic?  Is not making worse land ice melt (with resulting sea level rise) not a danger to the body politic?  All the other cases I didn't cite on both sides present similar dangers. 

The common thread here is that preferring political belief systems over objective truth is a clear and present danger to us all.  It seriously endangers our republic.  Perhaps it should be added to the definitions of treasonable activities.

 
I note the fact that many Democrats cannot accept the fact that Donald Trump is our President, I still see cartoon covers of President Trump on many magazines with titles suggesting "How we can fire Donald Trump!" The campaign has not ended for many Democrats, they are still attacking Trump o everything they can think of, putting up resistance and not accepting the results of the last election, this sort of behavior is a threat to democracy itself! If they cannot accept the results of the last election, then what can they accept? I've never seen so much hatred for a newly elected President, than I have for this one, yet he has not gotten us in any wars, has not presided over a recession that is clearly his fault, yet the Democrats were on full attack mode for day one, they don't seem to understand that there will be another election in less than four years, if they position themselves as the party that hates everything that is Republican, they are going to blow it, because most Americans don't care as much about Partisan politics as they do!

Perhaps dumbing-down our education system for easier control of the masses was a really stupid idea.  That is something I have personally witnessed and can testify to. 

If these things were made treasonable offenses,  routine activities in the House and Senate would certainly change.  Perhaps the White House as well. 

GW

With he emphasis on slavery instead of the abolition thereof. Also why did they get rid of Lincoln's Birthday as a national holiday and replace it with Martin Luther King's? Clearly who was the most important person for the civil rights movement, was it the one who freed the slaves, or the one who organized marches on Selma, Alabama? I thought it was a mistake to get rid o Lincoln's Birthday as a Natinal Holiday, maybe it was because he was a Republican.

Is there any chance of limiting discussion of Dictator A vs Dictator B to political threads?  None of that adds to the topic of this thread.  Can we talk about the science of our planet's climate and tools or technologies to use to combat pollution (something I think any reasonable person would agree is never a good thing if we can avoid it)?

When Science becomes perverted by Politics is a political thread! How can it not be when Politics is doing the perverting, and what is politics about than about who has power. Power is what motivates the Global Warming crowd, if hey conclude one thing about global warming and the public acts on it, they gain more power than if they conclude something else. If there is one thing science teaches us is the need to have a disinterested observer or experimenter. The reason why socialism, for example, is tried over and over again, no matter how man times it has failed, is because the experimenter is not disinterested, he is really not interested in finding out the truth, but rather to make a show to convince skeptics that socialism works, so he will doctor the results to show that socialism is the wave of the future so that the gullible masses will buy into it and give him power! With global warming it is much the same, it is an end of the world doomsday scenario which requires that if we are to survive, we must all pull together and contribute. Do you remember this movie perhaps? When Worlds Collide What is the movie about? About the end of the World, about people putting aside their differences, national boundaries and political differences to save humanity. Now people who watched this movie dream of something similar happening, so the need an "End of the World" scenario to have the same effect as in this movie. Since there are no rogue planets currently known to be on a collision course with Earth, Global Warming will have to do. So what they want us to do is panic, make sacrifices, and incidentally make their careers. it is a racket, a way of separating people from their money! When Worlds Collide is science fiction.

That's an intriguing story idea, Tom. Kind of along the lines of what astrobiologists call the "Zoo Theory". Question is: how do Human Beings stack up in their test of first contact? Are they violent or do they manage to pass the test? What is the criteria for passing?

The thing is that with simulations, you can do just about anything and still called it hard science fiction, so long as whatever it is remains within the simulation. So lets say the story is about a manned mission to Mars, lets say there are 6 astronauts, they are following a hard science mission, everything is laid out pretty much along the lines of NASA plans, the crew takes a number of months to travel from Earth to Mars, and they are all set to land their crew capsule or Mars hab. The Crew Ascent Vehicle is already positioned, it has made enough fuel for the return journey to Earth and everything checks out. Mission Control gives the crew the go ahead to land the hab on the surface of Mars. Little does the crew or anyone else know, that everything the experience is only a simulation. The program they are a part of, has a built in trigger. The trigger condition is that when a manned spacecraft reaches a certain altitude above the surface of Mars, the old Mars is swapped out for another Mars, this Mars has canals, an indigenous population consisting of a type of humans, and a breathable atmosphere. The capsule is entering the atmosphere, its heat shield is glowing, they've slow down enough so they can deploy their landing parachutes, and suddenly Bam! That atmosphere around them suddenly and expectantly gets thicker the crew gets pressed down on their acceleration couches as the wind outside suddenly wails, to make it more interesting, lets say suddenly they are in a rain storm with thunder and lightning, rain is pelting their windows and its making quite a racket. the parachutes are deployed. Mission Control is unaware of what happened because of the time delay between Mars and Earth, but an amateur astronomer looking through his telescope suddenly sees this Mars
True-colour_image_of_Mars_seen_by_OSIRIS.jpg
get replaced with this Mars
mars_terraformed1024_1.jpg
It all occurs suddenly as soon as the light reaches Earth, he sees the change. Mission Control get analomous readings, the landing crafts suddenly decelerates more sharply and starts drifting with the wind more than anticipated when the parachutes are deployed. There is a blue sky above and a sandy desert below, their crew ascent vehicle is nowhere to be found, the topography is the same as in the old Mars with some erosion, their landing site I now underwater, as a river now courses through the dry river bed that their mission was originally to investigate. They report the situation to Houston, and then they separate from the parachute, and their hab drops like a rock. The Pilot has to assume manual control, to prevent the autopilot from landing the ship in a river. The Pilot slows the craft, and carefully touches down on the shore of the river instead. Lightning flashes in the distance followed by thunder as the wind thrashes the hab as it settles on the muddy ground. After a time the engine shuts off, and there is only the sound of the wind, the thrashing rain and the sound of thunder. The crew looks out the circular windows of their craft in astonishment, their instruments read an atmosphere close to 1 bar of pressure, and the presence of oxygen is detected. After a time the rain settles into a steady drizzle. Messages from Mission Control catch up with the craft, they want to know what is going on. A patch of blue appears in the sky. The astronauts seem some men approaching outside on horseback, the horses gallop in an odd way in the low gravity, the men on the horses seem to be armed with a variety of medieval weapons, it is possible they could do damage to the ship with some of these weapons. What do you suppose the astronauts would do next? I don't think they brought any weapons with them, or at least nothing that was intended to be used as a weapon, there is a rover attached to the hab. Everything they need to conduct the expected Mars Mission is in the hab, the only thing they don't have is the means to return to Orbit, their Mars Ascent vehicle was swapped out with the old Mars and is no longer there. so here is the test, what do the astronauts do now?

The "natives" of Mars were descended from colonists from a parallel history that was also run in a separate simulation until this trigger condition was met. Their technological civilization declined until the reached their current state of development. As far as they're concerned, Earth is just a legend, a light in the sky where their ancestors once came from, they terraformed the planet, because in their timeline, human civilization developed much earlier than in ours. One possibility is that in their timeline Alexander the Great lived long enough to establish a stable empire, and line of succession was established, and science flourished, their descendants got into space one thousand years before we did. The languages the natives speak sound similar but not identical to ancient Greek, they seem to have a pagan religion, monotheism has not developed the way it did in our timeline, so they still worship a pantheon of gods and goddesses related to those of the Ancient Greeks.

Mission Control becomes aware of what happened, what they don't know is how it happened, everything else in the Solar System remains the same, the crew remains in contact with Houston, their mother craft continues to orbit this different Mars. Phobos and Deimos also continue in their orbits the same as always, nothing has changed about them. The President is called up, Congress is consulted, another mission to Mars with a rescue craft could be sent to Mars, but it will take a couple of years until the next launch window, for the time being the astronauts are stranded on Mars and have to make the best of things, including with the armed men on horseback.

As far James Starkey goes, you're right. He is 18 in Earth years at the start of the story (or 9 in Phaethian years). In fact we see him graduate from High School in the first chapter. My story is a little bit more down to earth (or down to Phaethon, whatever). Despite it's taking place thousands of years in the future on another planet, it's really just a story of a young man leaving his home and setting out in the world on his own.

Not being an electrical engineer,  I know nothing about motor and generator design.  The motors and alternators on my cars seem able to convert around 80+% of the mechanical shaft work into electricity.  I thought the big commercial generator machines were around 90%,  but that's not based on any real data.  The problem is the one-way efficiency of the lead-acid battery:  ~70%.  Which means you get just about half the energy back out of it that you originally put into it.  Supposedly,  the new lithium ion batteries do better than that. 

For uranium nuke power,  the pressurized water designs we have now are good enough,  but I would like to see the maintenance and safety design standards tightened up to resemble more what the US Navy has used since Rickover.  Fuel reprocessing would greatly ease the waste stream size,  but we want to be careful not to repeat the contamination mistakes of the Hanford site when we build the reprocessing plants.  The Yucca Mountain disposal facility would serve for a much longer time if the waste stream was smaller due to reprocessing.  And we need to address risks posed by bad siting hazard decisions with some upgrades. 

I am not a nuclear engineer either.  What I know about thorium is likely obsolete and incomplete.  Supposedly,  you put Th-232 into a uranium or plutonium reactor to breed it into U-233,  which is fissionable.  If you get enough U-233 reactors going,  it is supposedly possible to use them to breed the thorium,  relieving you of the need to have so many uranium/plutonium breeders.  The breeders aren't nearly as suitable for electricity production.  No commercially-ready designs currently exist for any of this,  as far as I know. 

But we need nuclear and natural gas to shoulder the majority load of electricity production until some sort of mass energy storage solves the intermittency problem with the renewables.  If the market shifts toward electric vehicles,  then electricity production means and grid improvements become even more crucial.  You have only to look at photos of Chinese and Indian cities to see that conventional pollution abatement as well as unburied carbon pollution are both addressed by this approach.  The benefits are quite real. 

Kbd512 may be right:  solar concentrator power with a heat engine-driven generator may be best for power plants.  But residential rooftop solar PV is quite important to address transmission losses in the grid,  as I mentioned somewhere above.  In many places this is best done in combination with a small windcharger. 

I really think both central solar concentrator plants and distributed-generation with rooftop solar PV make great sense and offer much promise.  So do the big wind farms,  as long as the transmission infrastructure is built with them.  I am glad these things,  especially small rooftop solar PV,  are becoming affordable and competitive.  As long as fossil fuel has subsidies,  so should these things.  That's the roughly-level playing field.

Oldfart1939 is right about fusion:  don't hold your breath for it,  but always maintain hope.  It's been "20 years away" for at least 65 years now that I know of personally. 

The rogue nuclear state problems with Iran and North Korea are going to get worked out,  one way or another,  Tom.  I hope we can do that without war,  but the odds favor conflict.  A lot of people are going to die if war comes,  but the vast majority of casualties will be in those two places,  and will be civilians killed because a minority of their number who are leaders insisted on being insane dictators living in luxury. 

What you have to remember to put this into perspective is that the likes of either country has only a handful of rockets and a handful of bombs small enough to ride those rockets.  Neither has both,  yet.  If they use them,  what they face is hundreds to thousands of rockets from the rest of the world,  tipped with many more and smaller bombs of greater yield.  They face total destruction. 

Because the dictators in those rogue states are demonstrably insane by any western standards,  they may actually choose to commit suicide this way,  and by doing so,  cause the genocidal obliteration of their peoples.  But they will lose,  and they cannot do us that much damage.  Bad,  but not our destruction,  certainly. 

The same level of risk applies to nuke weapons in the hands of terrorist organizations:  they can hurt us,  but they cannot destroy us.  The problem there is where do we strike?  My only suggestion is to strike at all,  just to make sure we get the right ones.  Many innocents will die,  since these evildoers have taken to hiding behind human shields in the heart of populated cities.  But there is no other way.

And,  Tom,  to balance your one-sided diatribe about Iranians,  the grudge their leadership and some of their people hold against us is that the US CIA put that popinjay dictator the Shah onto the peacock throne in Teheran,  by overthrowing their leftist-leaning president in 1953.  The shah mistreated them badly,  which is why the people plus the mullahs overthrew him by 1979. 

The mullahs installed a theocracy dictatorship in that power vacuum,  backed up by the Revolutionary Guard, their private army.  No different from Hitler and his SS and SA.  And we fundamentally caused all that for nothing but political ideology about a leftist-leaning president in what was then more-or-less a voting democracy. 

GW

I'm having a difficult time understanding what a "terrible" man the Shah was considering what the Iranian people put themselves through with their theocracy, it seems like in either case, these people were not ready to accept democracy, and while they were under the Shah, they were less of a threat to us than they are under the Ayatollahs! I think the Shah had more respect for human rights than the Ayatollahs did, women were certainly freer to wear whatever they wanted, the didn't have to cover themselves like they do now. Putting ourselves in this perspective, we didn't react to King George III and Lord North's Parliament putting a tax on our tea by installing an even more ruthless tyrant than he was! So what was the choice for us?
1) Left leaning President
2) The Shah
3) Islamic Theocracy
None of these choices is very democratic! Joseph Stalin was not a very nice man, we did not want to give him a base in Iran, so he could point missiles at us. There was and is something wrong with the Iranian People if they give us choices such as these, as if they are not ready to be free and live in a republic with a leader that does not threaten to overthrow such. The Iranian People are ultimately to blame for being so radical in the first place, for being the type that would accept a leftist leader who would overthrow democracy and give bases to the Stalinist Russians so they can threaten he rest of the free world! We let Venezuela have its leftist leader Hugo Chavez, apparently in an  attempt to apply he lessons learned about not interfering in Iran, he acted as a destabilizing influence in South America, sought to overthrow neighboring countries by sponsoring leftist revolutions in those causing a lot of death and destruction, and because of the mismanagement of Hugo, Venezuela now faces 25% unemployment and starvation, it might have been better off under a leader we picked for them rather than one the picked for themselves! Damned if we do, damned if we don't!

Also I might add that its been almost 40 years since their revolution in 1979! You think that a reasonable people would have gotten over their America hatred by now, no matter what you think we might have done prior to 1979. 40 years is about 4/5ths my life! How are my children supposed to understand these extremely hateful people? I don't think we've eve done anything so terrible to them to earn that kind of hatred, do you? Even the Jews don't hate the Germans that much, and the Germans did a lot worse things to them than we ever did to the Iranians, I can tell you that for a fact.

#10 Re: Terraformation » Practical Dyson Sphere: The keu to terraforming the Solar System » 2017-05-06 11:21:13

A Dyson Sphere is mainly to collect energy from the central star, think of it as a giant fusion reactor. Popular Science has an article about Dyson Spheres, their Dyson Sphere is a swarm of solar collectors in different overlapping orbits to intercept all of the star's energy, those collectors then beam energy to one another, and then beam it to where its needed. A ringworld can also be a part of this, as human habitats would be included and be one of the many places that receives energy from the Dyson Sphere. My idea of a Dyson Sphere + Ringworld is to have a Dyson Sphere the size of the orbit of Mercury. Mercury is taken apart to build the Dyson Sphere at about 2 kilograms per square meter, the next orbit out is Venus, and beam of energy reaches out to Venus to give it an Earth level of sunshine, it is terraformed and a pleasant place to live. The Earth is much as it is today, next out is the ringworld, it spins at an inclined angle to the ecliptic at a radius of 100 million miles, well outside the radius of Earth's orbit so as not to interfere, beyond the Ringworld is Mars, it is fully terraformed has a breathable atmosphere and is illuminated by a beam of light from the Dyson Sphere that is just enough to keep it warm and habitable. the asteroids are a bunch of space colonies that are illuminated by multiple beams of light from the Dyson Sphere. Jupiter is missing, much of its mass was used to make the ringworld. Saturn and its Satellites, plus those of Jupiter, now orbit Saturn, so it has 5 large Moons, all of them are terraformed, there is a solid sphere around Saturn itself and its outer surface is terraformed. Most of the gaseous atmospheres of Uranus and Neptune were removed, what remains are two Earthlike terraformed worlds illuminated by beams of light from the Dyson Sphere, the Dyson makes sure each body gets enough light so that it remains a habitable place for humans to live. that is how I see the future of our Solar System.

What? Iranians don't hate Americans, they just have some people in government who aren't very nice.

They have had the same consistently evil governments since 1979 when they overthrew the Shah. I would ask the same question about the Russians, why are their governments more often bad news for us rather than the opposite? What gives rise to their tendency to have evil governments that mean to cause us trouble and disturb the World peace? They are always trying to build their empires by reducing the amount of freedom in the World. I believe in peace, why don't they?

The Russians overthrew the Czar, was it because he was oppressive or insufficiently evil?, they replaced the Czar with the Bolsheviks, their leader promised "Land, Peace, and Bread" but did not deliver on any of those. The Iranians overthrew the Shah, whom they claimed was oppressing them, but they replaced him with an even more oppressive bunch of leaders, and warmongering ones that chant "Death to America" at that! Why should they be allowed to have nuclear reactors capable of producing bomb grade Uranium or Plutonium? the World was a much better place before they entered the scene and started destabilizing the region. We don't need the endless conflicts in the middle east that they tend to cause. if they would just seem to maximize their economic output and mind their own business, that would be fine with me, but they don't!

So what is the cause of evil rising to the top if they are not evil themselves? I would ask the same of the Germans who put Hitler into power, but perhaps they don't know the answer. Hitler made his attempt at World conquest and it cost Germany dear! Why would people want to put such a self-aggrandizing evil egomaniac in charge of their country? I don't think Germany was any better off because of him.

There are a lot of dead Germans who died fighting for Hitler's dream of grand conquest, why take the chance? Why couldn't they just live in peace and try to prosper? Ultimately the people are in the end responsible for the governments they have, the Iranians had a chance at democracy when they overthrew the shah, but they chose a theocracy instead, The Russians had two chance at Democracy, the first when they overthrew the Czar, the second when they overthrew the Communists, they failed at both tries, what the Hell is wrong with them! If Poland can have democracy why can't they?

Are the Russians too big to have a truly representative government? are the temptations to try and conquer the World at every opportunity just too great for them to resist? I think in the 1990s the Russians had  choice, they could either strive for more freedom in a free society or they can attempt to build another Empire and attempt to conquer the World, why do they always seem to want to go for the second? Why do we have such trouble makers in the World when we do not need them?

Do you want to die GW? What's so political about not wanting to die? Nuclear weapons are dangerous, and allowing irresponsible people to have them just because they the America is going to make us more likely to die, this is not a matter of opinion it is a fact. So I wa being a bit sarcastic to make a point about these knee jerk anti-nuclear activists, and its true, thy are not so antinuclear when it comes to out enemies having nuclear reactors, even if they are rich in oil. They don't want any new reactors built in the USA, but Iran, they understand those reactors are mainly for weapons production, though they say otherwise, they give lip service to the idea that they are to produce electricity. Iranians aren't interested in Thorium reactors, because you can't produce atomic bombs from them, they want the kind which they can produce atomic bombs from, though they deny it. Obama pretended it was to produce electricity, because he didn't want to do anything to stop them, and maybe to you its just politics same as the Presidential election, it is some kind of sport, yeah for the Democrats, boo for the Republicans, butin the end, If Iran gets the bomb, real people regardless of their political persuation, regardless of whether they love America not, they could die! You understand? Iranians hate America, and th only way they can express that hatred is by killing Americans, Democrats, Republicans, liberal, or conservative, it doesn't matter to them! I don't want these people building any nuclear reactors, whether they say its for commercial purposes or not, I don't trust them!

GW,

Liquid core nuclear reactors eliminate most of the problems with fuel re-processing and storage issues, along with high pressurization and explosion hazards from hydrogen gas production in solid fuel light water reactors, even if a few new ones are created.  Liquid solutions are much easier to chemically process than solid fuels.  Instead of a crash program to create a battery technology suitable for utility class electrical power storage, how about we just figure out how to design and implement liquid core reactors since we actually know that technology already works?  We've pursued utility electrical power storage batteries for decades now with nothing practical to show for it, much like hot fusion.  Maybe, just once, we could focus our engineering efforts on problems that don't require materials or technologies that don't exist.  We can and should still pursue new technologies, but the 1970's liquid core reactor technology was proven to be functional before I was born.

In any event, I think practical applications for batteries and super capacitors are more in line with the requirements of electronics and motor vehicles than grid power storage.

The issue I see with motor vehicles is our "use and then throw away" mentality combined with the "planned obsolescence" business model.  A motor vehicle should be something you buy once and then repair as required.  Only the power train should require routine upgrade or parts replacement.  The chassis and body panels should all be constructed of high grade stainless steels, not plastics or low carbon steels prone to corrosion.

You know most liberals and leftists are fine with the old style nuclear reactors that produce weapons grade plutonium just so long as its produced by an unstable regime that isn't friendly to us! Where I live, liberals don't like Indian Point because its not run by fundamentalist Shiite Iranians who chant "Death to America", and who want to make nuclear bombs, instead it is run by people who want to sell us electricity. I discover that many a liberal's antinuclear stance falls by the wayside then the people who want to build that nuclear plant are people that hate America! I used to be more even-handed between the Republicans and Democrats, I even voted for Bill Clinton twice, but with the election and reelection of Barack Obama, I found out that Democrats really hate America and would like to see it destroyed! Barack Obama has gone out of his way to see that America's Enemies have access to the technology that would allow them to build nuclear bombs, Barack even paid them some money in the guise of paying Iranian ransom demands in the amount of $100 million per hostage! You know what those nuclear bombs threaten the most? America's big liberal cities, that' who, those cities have high concentrations of people, and for a country like Iran or North Korea, which is likely to have only a few nuclear weapons to start, it would only make sense for them to target those cities. They could try targeting our fixed missile silos, but they would not get them all and would not end up doing much damage to our country, as they will get the full retaliation from every missile silo, submarine, and bomber they have not destroyed. the only thing that makes sense for their perspective, if they are willing to die, would be to destroy our cities, or as many of them that they can target, starting with the largest ones first as they have few nuclear bombs! They are going to die anyway if they are going to nuke us, but if they don't mind that and are willing to sacrifice their lives, the only targets that make sense would be our big liberal cities that supported Barack Obama and Hillary Clinton!

I find the Obama Administration to have been very pronuclear when it comes to our enemies, they didn't mind if they used poor and dangerous designs, they didn't care if they released radioactivity through nuclear accidents, the point was that the Iranians and North Koreans get their hands on some Plutonium so they can deter us from invading, because Donald Trump is going to be "so worried" over what the North Koreas are threatening to do to our big liberal cities on our west coast, that have shown how much they hate Donald Trump, particularly in Hollywood! So what do you think our President is going to do about the North's nuclear weapons tests? Do the people of Hollywood, who voted for Obama and Clinton, have something to worry about?

Interesting speculation. But how would this be different than a religious perspective on the Universe in which God created everything just for us. How is a simulated universe fundamentally different from a created universe? I mean, in either case, everything we see would be "simulated" by some sort of outside intelligence for some sort of mysterious purpose.

But to answer your question from earlier, Tom. The "James Starkey" story starts out in 5928 A.D. on Phaethon. The name is familiar because Phaethon happens to retain much of the language and culture from pre-apocalypse Earth. Of course, they don't call their year "5928" as our Gregorian Calendar is no longer used anymore.

So according to your timeline James Starkey is 18 years old at this time, since he was born in 5910 AD.

Actually a simulated universe is a created universe, but if we're going to simulate just the Earth, we don't have to simulate the entire universe, we can simulate the images of stars we see through telescopes, we could simulate the Solar System, and there is a device which could possibly simulate all of this, the Mastrioshka Brain.

Now imagine a galaxy that is just full of civilizations, there is one elder civilization, the first one to arise in the Galaxy, it has witnessed the destruction that occurs when two civilizations, one of which is vastly technologically superior to the other, happens to meet, and what usually results is that the less advanced society gets destroyed, whether the advanced society wishes for that outcome or not. After this happens a number of times, (think of the Europeans first contact with the Native Americans in the New World) the elder civilization decides to do something to preserve all these intelligent species they come in contact with.

The first thing the elders do, which from hence we shall call the preservers, is to dispatch a number of Von Neuman probes, these probes travel to star systems, explore them, and use the local resources to build copies of themselves, over the course of about 3 million years, they have explored and catalogued every star system in the Galaxy, if an intelligent tool using species is discovered. the probes do one other thing, using local resources they make a number of copies of themselves, and they begin taking apart planets to build a Dyson Sphere, this takes the form of a swarm of solar collectors, each one in an independent orbit around the star. The probes then disassemble the life found, up to and including the entire ecosystem and the structure of the planet itself, uploading all the creatures including the intelligent ones into a computer simulation run by the Mastroika Brain that the Von Neumans created the simulation is of the entire star system that was disassembled prior to the disassembly done by the Von Neumans. The creatures that were on the planet wake up in the simulation and find that nothing has changed. When a civilization develops on the simulated planet, their astronomers see stars and galaxies in the night sky but no sign of extraterrestrial civilization, they can explore their star system, and maybe even send starships to other nearly simulated stars, but everywhere they look, they find no evidence of intelligent life, this is a deliberate setup by the Preservers, as they wish no contact between this civilization and others in the Galaxy including themselves, they simulate the laws of physics faithfully up until some point where the believe the nascent civilization can survive contact with other species. Prior to that the set up a little test involving contact between two different civilizations, in this example it is the civilizations of Earth and Mars.

One can do a number of things with this idea in a story.

Tom:

(1) what you said in your first attempted "refutation" about small vs large business has nothing at all to do with what I actually said.  I do partly agree with you about small business providing more jobs than big business,  yet suffering more under idiotic regulations.  That does not mean we do away with regulations:  that leads to piracy and economic slavery.

It means we put some real rational thought into what we regulate,  and how we regulate it.  I have not seen 1 politician in half a century capable of evaluating that.  Most bureaucrats are rather stupid,  too.  Part of the EPA's problems and bad reputation derive from the fact that lawyers now outnumber all other professions among their payroll.  If you have ever actually read any EPA regulations (I have),  then you know that too many lawyers are the fundamental problem there. 

BTW,  there is no such thing as some vast monolithic "Media" engaging in some conspiracy against us,  or against Trump.  There is only editorial bias among the major outlets:  NBC is as flagrantly biased for the Democrats as Fox (Faux?) News is biased for the Republicans.  But the basic facts of the stories are the same,  if you actually bother to compare.

 
Funny that you can list only Fox News as being on the conservative side, but you have NBC, ABC, CBS, CNN, MSNBC, kind of unfair that we have so many TV stations pushing the leftwing point of view and only one Fox news to counter that, technically not a monopoly, but it is very close to being monolithic, and here you are trying to diminish that one TV station that is on our side by calling it "Faux" News, seems like you desire a monopolistic News Media that allows various left wing politicians to sweep dirt under the rug instead of solving our problems. Once you get rid of Fox News, how would we be different from Cuba? You will get your one-party state with politicians that can do anything they want, now competition, no challengers, the News Media won't cover them or worse, they will try to smear them like the attempted to do to Trump by calling him a "Fascist" and saying he has no chance to get elected in order to depress his voters into not showing up at the polls!
marine.le_.pen_.jpg
I wonder how bad Marine Le Pen is? The Media says she's a racist, but the Media also said Trump was a racist, I wonder if I can trust the Media? How much of it is actually her and how much of it is just the Media trying to smear her and call her a fascist? If the Media called Trump a Fascist and he's not, how do we know anything about her? What if she is a fascist? Well then there are some French people who will compare her to Donald Trump, they will say that the Media did a smear job on Trump and they are doing the same to Marine Le Pen, and they will go to the polls and vote in Marine Le Pen as the next French President, and it will in part be the Media's fault if that happens and she turns out to be a Fascist! You ever hear of "The Boy who Cried Wolf?" The Media has been "crying Wolf" at every Republican candidate for President since George W. Bush! So why shouldn't we take our chances with someone the Media calls a "Fascist?" How can we tell the real ones from the smear jobs the media produces? The Media wants us to elect one certain candidate and they will call everyone else a fascist, or a racist, or someone who is unkind to animals, or someone who is too rich when they are a Republican but that ignores their wealth if they are Democrats! I am sick of it, and I want my country back! I am sure many French People feel the same way about France!

(2)  Your second and third attempted "refutations" are patently ridiculous,  as was the plot (and the not-science behind it) in the movie you mentioned. I never said anything about walls of water or anything suddenly freezing.   What I said was two-fold:  it will be very difficult and expensive to move critical fixed assets to higher ground (especially if we have to do it quickly,  as within one lifetime,  or at worst within a decade or so),  and (2) people will migrate (they WILL NOT stay and drown!!),  and there is no place to put them,  nor will there be food to feed them.  The bigger the migration,  the more inept and unprepared we as a species will be to handle it,  as recent events have proven.

Where do the Japanese get a lot of their food? You see this map of Japan? What do you think the Japanese would do if the ocean levels rose? Japan looks very rugged, does it look like they grow a lot of their food on land? A lot of their food comes from the ocean, they have fishing fleets, what do you think would happen if the ocean levels rose? They would just have more places to fish, that is all. I don't think the Japanese would starve, they can build factories on higher ground, export cars and import wheat from other places, and meanwhile their fishing fleets would go out and pull in nets full of fish. Fish are a major part of their diet, more water equals more fish to eat, I don't see them starving!

(3)  Your 4th attempt at "refutation" was also stupidly ridiculous.  It has nothing to do with anything I said about climate change.  Without asking where I have been,  you just told me to move north.  I did spend two winters and a summer in Minnesota about 20 years ago.  Those were 100-year record setters for cold and snow.  Yeah,  I've seen both hot and cold,  up close and personal.  I tolerate the heat because for me shoveling snow was worse.

Well maybe the folk in Minnesota would like to shovel less snow as well. Global Warming could give them milder winters. As for moving, if you can move from Texas to Minnesota, don't you think other people can move away from the coast, or are all those coastal people a bunch of poor mud hut dwellers? Lets take a look at some of those properties on the coast.

1260.jpg
Here is another property on the coast, such poor unfortunate people, having to live in a place like this. How much do you want to sacrifice to save their homes?

(4) Your 5th and last attempt at "refutation" also has only tangential relation to what I wrote,  which was to quit using long-buried carbon as fast as we can.  I DID NOT say how!  YOU claimed I said government mandates,  I did NOT say that,  as your copied quote of my text clearly shows! 

Actually,  and your politics will make you hate this,  both solar PV and natural gas are already cheaper than coal,  and both are very much cleaner than coal,  in both the traditional pollution,  and in the carbon emissions pollution.  And they are ready to deploy.  That is why they are already displacing coal in the marketplace,  just as they should. 

And before you yammer about subsidies,  the fossil fuel people have had subsidies for about 150 years now.  So with subsidies for wind and solar,  the playing field is more-or-less level,  just as it is.   Either leave them be,  or take them all away. 

As for MPG standards,  as long as they are not specific as to how,  they do play a valuable role in incentivizing engineering innovation. If overdone (and perhaps they are),  cheating gets encouraged.  So perhaps we should revisit how much and how fast,  but I'd think we really do want to keep them in place,  in one or another form,  in order to help push along the transition away from fossil fuel,  as I put it "at best possible speed".   

That last has nothing to do with politics (although it does violate your "totally unregulated free market" fantasy,  which is an evil we've seen before in history).  It's just something practical to do when faced with an oncoming trouble.

The only people trying to obscure the facts are certain giant business interests who will have to undertake change in their basic business models,  or else lose profit.  That's not politics,  that's just greed and laziness on their part.  The greed has demonstrably been unconstrained by ethics for a couple of centuries now in US society,  at least.  So I wouldn't believe much of what they have to say.  Yet those rich entities have long bought politicians to get what they want out of the government.  So don't believe the politicians,  either.

Those politicians don't believe in profit either, they believe in wasting your money on themselves and their cronies, and if they run out, they just grab some more from your pocket, does that make them any better than those "greedy businessmen and businesswomen who are only interested in making a profit? They cannot legally steal your money unless they pay some politician to steal if for them!
The businesses that I want to see more profitable are the small to medium-size businesses, the ones that create most of the jobs. The policies the Democrats advocate hurt small to medium sized businesses the most with their taxes and regulation. When I think of a business, I am thinking of a small to medium sized business, not the giants like Exxon Mobil for example. The giant businesses can always bribe politicians to go steal your money for them and spend it on their "pork", which they sell to the government. Liberals don't like energy companies or defense contractors, they love universities and the entertainment industry however, they love to control the information that reaches the voters through their control of the media, we re seeing that being played out with the endless attacks by the Media on Trump. The Media wants to control this country by controlling what you perceive, and that way they can control what and who you vote for! When the news isn't objective a democracy becomes undemocratic and a republic unrepresentative!

The sooner you get that "it's not political" concept past your political-tinted-to-the-point-of-opaqueness glasses,  the sooner you can actually understand what has been posted here.  So far,  you do not. 

I pointed out with real data that if the land ice melts to one extent or another,  that sea levels will suddenly rise by one closely-related extent or another (density-corrected conservation of volume).  And because so many of our fixed assets and our population live very close to current sea level,  the effects of that sudden rise are likely quite severe,  to potentially rather disastrous.  I showed you a non-political logical means to decide what to do,  that works even in the face of imperfect information.  That trade matrix technique is a very common decision-making tool used in business and industry.

 
You mean like a wall of water suddenly crashing into the skyscrapers of Manhattan from those suddenly melted glaciers on land and all the freshwater releases into the ocean is going to weaken the Gulf Stream causing all that water to suddenly freeze into solid ice? That is the plot to the Day after Tomorrow That is the sort of thing that will kill people, they will either die when that wall of water crashes into them or they will die when all that water freezes solid. Now do you really believe that is going to happen?

For you to deny the objective facts of ice volume at risk is illogical in the extreme,  and thus evidence that you prefer political belief over objective truth.  That way lies madness. History before there was science so very clearly shows this.

   
How do people down in a slowly rising ocean? You can have a few hurricanes, but most people will say it was the hurricanes that killed them, not global warming. We have things called weather satellites that warn of approaching hurricanes and if they get out of the way of those, they won't die, if they are suborn and refuse to move, then you can say it was their stubbornness that killed them!

It's not really about the scientists and their temperature estimates and their climate models.  I distrust that stuff myself.  It's about the volume of the melting ice:  how much more is going to melt?  That's how much the seas are going to rise,  and just as fast as that ice melts.  And it IS melting,  when it wasn't a couple of centuries ago.

 
What's wrong don't you like warmer weather? Then why do you live in Texas? it would be much easier for you to move North than to halt global warming. You get into a car, pack a moving van and drive North and to higher ground if you must.

It simply makes common sense to attempt to ward this off,  or at least try to slow it down.  While our knowledge is imperfect,  there is enough that is well-known to be confident of what we should do:  stop unburying and burning long-buried carbon,  at "best possible speed",  whatever that turns out to be.  Simple as that.  It might or might not work,  but it makes no sense at all not to even try.

The best way to develop alternatives is not to force them on people before they are ready, it is not to arbitrarily increase MPG standards in cars, that is what liberals call a "solution". We need to develop the technology first and the technology itself, when it is ready, will encourage the switchover, not government coercion.

The Martian is a fairly realistic book and movie about Mars. Most near future books about Mars are about astronauts getting in trouble, as was the case in The Martian. Mars is pretty much a blank slate except for what we know isn't there, there is no breathable atmosphere for one. We can speculate about what might be there that we don't know about.
mars-curiosity-rover-gale-crater-beauty-shot-pia19839-fi.jpg
We get an idea about what used to be on Mars. Both the Moon and Mars have ancient surfaces, but Mars has an ancient surface where there used to be water and perhaps life. Mars is kind of a monument, it is a giant headstone attracting our attention. This is primarily because Mars shares some features in common with Earth. Venus has a similar size, but Mars has a similar rotation and axial tilt, it is the one major body in the Solar System with a rotation rate that comes within an hour of the Earth's. Isn't it curious that we have seen no evidence so far of any extraterrestrial civilizations, the Fermi Paradox in other words? What if what we think is the universe is nothing more than a gigantic computer simulation? Such a simulation must have a purpose. A simulation can do all sorts of things, but the simulation we are in seems to simulate nothing but real world physics, what if that stops once we land people on Mars. No human has ever set foot on the planet, and a computer would know the difference between a human astronaut and a robot probe. Maybe the real universe is actually crowded with advanced technological civilizations and they built this simulation of us alone in a lonely universe? What if there is a trigger or a key on Mars which changes the parameters of that simulation? Mars is like a giant billboard, maybe there is something there that we were meant to find once we were deemed ready. A simulation of an entire world is very expensive, and is bound to get even more expensive as we expand into space within that simulation, at some point things have got to change.

Yes, there are a number of different versions of it, they all involve different ways of scoring a hit and taking damage, the most common versions use 6-sided dice only, there is one published by Mongoose, there is the out of print T20 Traveller which is more compatible with Dungeons & Dragons and the different dice used in it. Typically Traveller characters don't have levels, but T20 characters do, though T20 has a system to counter the mounting hit points with increasing level. Unlike D&D characters, Traveller characters don't become more powerful with experience, they gain new skills, but are just as hard to kill as they were before. Most power comes from all the things and wealth a character accumulates, rather than the new abilities he has, with D&D its all about the abilities and hit points, thouh wealth accumulation is possible too. In D&D rulers tend to be high level characters that are very formidable in combat, they often don't need security guards to protect them, in Traveller Emperor Stephon is just an ordinary bloke in a high position of power, he needs that security detail, and if you want to get to him, you have to get past those guards first, that is the hardest part!

Yes, I am greedy, I like to keep my money when I go to fill my gas tank at the pump, and I don't like to give to Arab charities such as Islamic Jihad, Hezbollah, Al Qaeda, or the Islamic Brotherhood, that is why I like to develop domestic sources of energy! How exactly did the Federal Government acquire this land in the first place? By declaring them "National Monuments" by Presidential Fiat? You understand that most of the land out West is owned by the Federal Government and was acquired by this means? You also understand that the Federal Government has $20 Trillion in debt? What happens if the Federal Government sells this land to pay off he debt? Then it can balance its budget without raising taxes, maybe even cut taxes and grow the economy for a change, then we can fund an ambitious space program!
