Weapons of Russian design doesn't automatically mean Russian supplied weapons.

But yeah, this is what happens with an open border.

The real news here is that they had the ball bearings to hit a military base, and didn't aim for a mall.

Whats to keep solar wind from blasting all the gas away.

Tell me Larry, when JFK attempted to overthrow Castro at the Bay of Pigs, was he being a republican thinker, or and Imperial thinker? What about when he said that we would bear any burden, or face any foe for the cause of human freedom? Or when he declared himself a member of the besieged and oppressed people of Berlin? Or when he risked everything to deny the Soviets a first strike capability in Cuba? Is the idea that human freedom is the single greatest resource born of republican, or imperial thought?

You see you can have the greatest public infrastructure on Earth, but unless you have principles and willing to stand up for them, it won't mean a thing. The Roman empire had a nice infrastucture. For centuries they used it to enforce the glory of Rome on the Mediterranean basin and beyond. In the end they compromised, were compromised, and destroyed. Hitler too had the Autobahn, and all it did was give his foes a smoother road to the heart of the Third Reich. Infrastructure is means to an end. If that end is right and true that road is blessed, if not it is cursed. Our founding fathers gave us the right end, but the road to it often difficult. JFK knew this by learning it the hard way. He failed to give the Free Cuban forces the support they needed. As a result he found himself in a position of risking a nuclear exchange that would have destroyed civilization as we know it. We took the easy way out, hoping the situation would improve on it own. We are still paying the price for that as Castro inspires a new generation communist dictators in South America. There are many similar examples following WW2. President Bush is dealing with them, not in the most effective way possible to be sure, but stubbornly facing the uphill fight none the less. Which is more than his political opponents can say. You, and they, might say that such uphill battles are expensive, and get in the way of the many wonderful services we can provide our people and in some ways your right. But if you continue to take the cheap way out on international disputes they will not be solved, and they will pile up until are in a peril we can not yet imagine. And it won't matter how shiny our trains are. I do know history, and all these things have happened before, and they will happen again if we fail to heed them.

Don't get me wrong, I agree that our public infrastructure has been ignored too long and the a reinvestment into it would work wonders economically, but I also know that it ain't worth a hill of beans unless America stays free, and the same freedoms are not taken back by oppressed people the world over. You can have the nicest medical, transportation, or education system in the world, but unless its people have the liberty to build their lives within it as they see fit, or even try and fail, such a society will rot out and die.

If you want to argue the best monetary system to get there and the specific infrastructure improvements that should be made go right ahead. But don't mistake it for "imperial thought".

The Hill: Obama unveils education proposal

Overall, Obama’s proposal would spend $18 billion per year on early education and K-12 education, including for teacher training and retention. Obama highlighted a variety of offsets to pay for the funding, including delaying the NASA Constellation program for five years.

A spokesman for the Republican National Committee (RNC) criticized the NASA cut.

“It is ironic that Barack Obama’s plan to help our children reach for the stars is financed in part by slashing a program that helps us learn about those very same stars,” said Danny Diaz, RNC spokesman.

MSNBC:  OBAMA'S EDUCATION ROLLOUT

Though Obama called for a renewed investment in math and science education, his plan would actually pull money from the federal government's greatest investments and achievements in math and science. Obama would delay funding for the NASA Constellation program for five years, though he would maintain the $500 million in funding the program would receive for its manufacturing and technology base, in order to help fund his education policy. The campaign did not say how much money delaying the program would provide.

The feed back from one of Obama's supporters says it all:

This is what I called leadership. Obama seems to be the only candidate that gets it. Education is the bead rock of every nation.

If you are still undecided you had better jump in before the train lives you behind.

Obama all the way; his ad was even impeccable.

Check it out.

How are you going to get the gas to stay in geo orbit at any bars?

#232 Re: Martian Politics and Economy » How do you build a physical economy? » 2007-11-19 09:51:30

Most of what you are being taught in school or colleges isn't really the American History that really happened, it was re-written to conform to the British interest inside the United States. Not only does it apply to the rail roads issue, but it also to the US Economic policies to line of with British interest too.
Larry,

I thought the only interests the Brits had in spreading propaganda in the Colonies was to convince us the Huns where bayoneting babies so we'd bail them out of the world wars.  wink

Back on topic, I don't think anyone is going to dispute that an overwhelming amount of the prosperity the US enjoys is due to investment of public funds into public infrastructure, and the economy is built on that foundation.

The trouble begins when the government trys to use the same kind of government infrastucture in the social sphere to change behavior, create dependance, and thus creating a captive voting block to preserve power. This conflict, the fight over the public treasury for social programs vs. "fiscal responsibility" and political distraction it has caused has taken a toll on our infrastructure. Settle that issue, and the focus will shift back where it belongs.

#233 Re: Not So Free Chat » Oil Prices Surge to Record Heights - 90 US Dollars » 2007-11-19 08:53:20

False.  This is issue is generally poorly understood, even within the scientific community.

Global oil discovery peaked in the 1960s and global crude oil production peaked in 2005.  Most of the increases in recent years have come from condensates and natural gas liquids, which are generally located in deep water or are associated with natural gas production.  They are more expensive to produce than conventional crude.  Total liquids peak may occur as soon as 2010.

Undeveloped reserves are available in the Arctic, off the coast of Brazil, west Siberia, West Africa and Antarctic.  But these reserves are far more expensive and difficult to exploit than 'conventional' crude, and are often located in politically difficult areas.  New developmnets must meet not only expanding demand, but must replace depleted production from existing oil fields.  With each passing year it becomes more and more difficult to achieve that.  Eventually, probably very soon, we will witness a peak in total liquids production.  This represents the point at which the effects of depletion within existing wells overwhelms our ability to bring new production on stream.  At this point, plenty of oil will be left in the ground and the world will still be producing a great deal.  But production will decline continuously with each passing year.

We've been finding sources of oil for decades that are "not economically viable" because it would not be profitable to exploit it at the current oil prices. But thanks to genius of Nancy Pelosi in collaborating with the Syrians/Iranians to give them Iraq by sparking a war between Turkey and Iraq, oil is now nearly $100 a barrel, and all those previously unprofitable sources are now a gold mine.

If you combine those even a trickle of new finds, we can get by.

Hydrogen is the least promissing of all alternative fuels.  It suffers from a critical efficiency problem that makes it unsuitable as an energy carrier.

The technology that is most promissing for road vehicles in terms of overall energy efficiency and technical practicality is electric, probabaly a combination of battery and flywheel electric power and conductive transfer, via an electrified conduit embedded within the roadway.  In the near term, electricity production is likely to come from coal (increasingly in highly efficient combined cycle gassification plants) declining amounts of natural gas and oil (burned in combined cycle plants), stable contributions from hydropower, small increases in other renewables such as wind, wave and solar and stable or slowly increasing contributions from nuclear.

I am very confident that hydrogen powered vehicles will never be a mainstream technology.

Slot cars?

If we all start building our roads like the Autobahn, it might work. But I don't see that happening, we have a hard enough time keeping up with potholes. And you can't base a national Energy/Transportation policy on a patchwork of state and local governments who can't handle potholes. Barring a major shift in US politics thats not likely. Battery-dominate hybrids that charge overnight and get the first 30-40 miles gas free are possible.

Hydrogen is the ONLY power source that can meet both the mobile energy need and the environmental requirement. It is the only clean fuel out there, all others are either not viable for mobile uses or release less, but still release CO2. It does require more energy to produce than it returns, but the production is stationary and open to a host of powerful sources like nuclear and tidal.

US ethanol production will die a quick death because of its very poor EROI (energy return on investment) which is about 1.3 at best.  Fast growing algae are a more likely energy crop, given that they can be grown in saline water on otherwise useless land and have a much higher conversion efficiency for sunlight into carbohydrate than any landbased plant.  These makes them very fast growing.  there may be small contributions from crop wastes, but these will be limited in the future by the need to use composted wastes as soil stabilisers.

All biofuels are much more efficiently used in highly efficient electricity plants, rather than as liquid fuels for car engines.

Algae is oil, it just skips the millions of years in the ground. Whatever reduction in initial CO2 release will eventually be recover as the 3rd world industrializes.

#234 Re: Not So Free Chat » Oil Prices Surge to Record Heights - 90 US Dollars » 2007-11-16 22:15:53

The fuel crisis is largely a myth. Theres more than enough oil around if we were only allowed to drill for it. Brazil just fund the 8th largest reserve just off shore. Theres also far to many blends of fuel mandated by various states,  artificially limiting supply. Taxes are also sky high.

The only real technology that really need development is fusion for grid power. The future of mobile fuel is hydrogen, and we already know how to use it. The limiting factor is the lack of infrastructure investment on production and distribution, and the fact that consumers can't afford the technology while paying $3 for gas.

Biofuels will never take off as a mainstream fuel because its food or fuel, not both. Its already driving up the cost of food because of backwards government mandates. Until all produce is grown exclusively in local greenhouses and all farmland is dedicated to grains and fuels, it will never be more than a bureaucratic abomination. Once that is overcome, it shows promise in limited off-road apps where its more practical to have an easily portable liquid fuel.

this could be a problem...

First Stage Design Problems Arise For NASA's Ares 1 Rocket

NASA has run into some problems with the design of its new Ares 1 launch vehicle - problems that could affect its ability (as designed) to safely launch its human cargo into space.

The Ares 1 and the Orion capsule (also under development) are designed to replace the crew carrying function of the current Space Shuttle fleet which is due to be retired in 2010. The first flight of humans aboard an Ares 1 is planned for March 2015.

According to NASA sources, the Ares 1 first stage, as currently designed, would produce a frequency of 25 Hz at liftoff. The concern is that this oscillation could shake the Ares 1 upper stage and Orion capsule designed to carry human passengers, causing considerable damage and that it could also adversely affect the Guidance, Navigation, and Control avionics in the rocket's Instrumentation Unit.

When asked to comment on this development, NASA's Exploration System Mission Directorate (ESMD) Public Affairs Officer replied:

"The Ares Project Office identified Ares I thrust oscillation as a potential integrated stack challenge as a part of its system definition review which concluded in October. Thrust oscillation or resonant burning is a characteristic of all solid rocket motors. It is caused by vortex shedding inside the solid rocket motor, similar to the wake that follows a fast-moving boat. When the vortex shedding coincides with the acoustic modes of the motor combustion chamber, pressure oscillations generate longitudinal forces that may affect the loads experienced by the Ares I during the last phase of first-stage flight. NASA is assessing the analyses in more detail, looking for any potential impacts to the integrated stack and ways to mitigate those impacts. Results are due in spring 2008. It is a normal part of the development process to identify, mitigate and track challenges such as this."

NASA sources also report that the 6 month slip in the Ares 1 PDR (Preliminary Design Review) recently announced could impact the first launch of humans aboard an Ares 1 by as much as 14-16 months beyond the publicly announced first flight date of March 2015.

NASA ESMD's response: "NASA decided to move the Ares I first stage preliminary design review to summer 2008 to allow better alignment with current Ares Project and Constellation Program preliminary design review planning. Conducting the first stage preliminary design review in summer 2008 will not cause NASA to delay the target date for the first flight with humans."

In addition, NASA sources report that the option of having a non-recoverable first stage for Ares 1 is also still under active consideration within the Ares design team - this despite stern statements to the contrary by former ESMD head Scott Horowitz last year.

NASA's response: "NASA is not considering a non-recoverable first stage for Ares I. A recoverable system is the preferred approach, and the agency confirmed this baseline through a trade study as part of the recent systems definition review."

#236 Re: Martian Politics and Economy » How do you build a physical economy? » 2007-11-16 00:16:22

The government does absolutely nothing without tax revenue. The government only gets tax revenue when suitable numbers of people devote their blood, sweat, and tears to bettering themselves and their surroundings (to suit them of course). Commerce starts do to the natural uneven distribution of resources required to do this. Governments develop to facilitate commerce and ensure it doesn't devolve into simple pillaging, and taxes are needed to make a government run, so they take a little of the top of the commerce, to facilitate the facilitating.

Nations develop when pioneers go to a (more or less) empty spot of land to build a better life for themselves independently or in a sufficiently different way than those already exist. People do the best they can with the patch of land they can exploit, sell whatever extra they don't need to live for something else they want or need to get by. They decide that this would be a whole lot easier if their was a road between us and those lazy guys would stop stealing our stuff, and create and contribute to a government to facilitate those things. Fast forward 250 years, and those people decide it would be a good idea to fund missions to other far far away plots of land cause the journey would create lots of new technologies  that facilitate wonderful new things at home, plus people would do great things like pay lots of money and donate time and effort for the adventure of going to those far far away plots of land.

As for how all this applies to space, it is basically the same pattern, and is not at all unlike the public infrastucture projects mentioned above. People and governments with the fore site to do it invest in the technologies and hardware by giving out tax revenue to those who can figure it out, and launch the missions. Those on the missions get the land and resources, those companies that did the research get to sell the technology, and the government gets a slice of that commerce. With time those off world offer goods and services not available on, or more likely, provide things that can be made quicker and more conveniently than shipping from Earth to facilitate furthered expansion, or perhaps something that we don't know about that can only be had there.   

On the tactical level, after a intense study of Mars and it resources, perhaps completely from orbit, multiple bases will be established based on abundance of various resources, be they water, various gases, minerals, convenient locations for habitation or access to orbit, ect. Trade develops between them, public infrastucture is established. Labor is imported. And so on.

#237 Re: Interplanetary transportation » Space Elevator or Scramjet? » 2007-11-15 16:32:50

I think scram jets will do it first, and is vital to pushing development of the other. If airline style Earth to LEO service can be established and the price of a ticket can be brought down from the current $200K to something more reasonable, then normal people will actually do it. And those normal people will demand a destination, which will push space development that only a space elevator can provide.

#238 Re: Human missions » Armstrong Lunar Outpost - status » 2007-11-15 15:49:00

The key to long term, affordable lunar exploration is creating permanent masonry structures out of the local soil, and putting large numbers of these kind of cheap inflatable habs in them. This is best done with robotics.

#239 Re: Not So Free Chat » Mars + Human = ? » 2007-11-04 16:58:54

Human behavior on Mars is dependent on the who gets there first, and who is allowed there, and under what circumstances.

If the free countries get there first and preserve the sovereignty of the planet for the colonists and view it's inhabitants as equal members of a greater human family, and the peoples of the planets share the lessons of the journey and ultimately work with each other with mutual respect, then we can expect relative peace despite the inherent hardships for the inhabitants of Mars, and greater prosperity by their sponsors on Earth, and by extension all of humanity.

If totalitarian regimes manage to occupy space, you can expect them to use this ultimate high ground to wage war on free countries and free minded peoples. Any accomplishments by either will be paid for with a tremendous amount of human lives. Colonists will use their isolation as a shield, and as time goes on we risk creating generations of hatred between Martians and Earthlings, and interplanetary war.

If we have a real horse race, we can expect battles for survival in space and battles for supremacy on Earth involving the worlds superpowers and worst weapons. Colonists fed up with the conflict will seek neutrality, isolation, and we will lose all the fruits of our labors.

#240 Re: Interplanetary transportation » Ares V (CaLV) - status » 2007-10-31 22:06:51

Just think about that. How much usable interior space would a Bigelow/Transhab module built to fit into a 12m shroud provide?

It would dwarf the ISS in one shot.

#241 Re: Human missions » International Space Station (ISS / Alpha) » 2007-10-31 21:40:51

Evidently it's not hurting power output a whole lot, but they are concerned about it tearing further.

#242 Re: Not So Free Chat » Oil Prices Surge to Record Heights - 90 US Dollars » 2007-10-31 08:29:30

Getting rid of Bush will not solve the world's problems. However, it will go a long way towards solving America's problems.

And just what would those be?

Would they include a list things like the lack of action on the growing terrorist stronghold in the tribal regions of Pakistan, the lack of leadership on setting a hard deadline on Iranian uranium enrichment and support of terrorism in Iraq and Lebanon, the failure to build up to United States Military to better deal with such threats and depending third parties such as contractors who's primary concern is getting out of a firefight alive and locals who inevitably have their own agendas to push to perform vital reconstruction and security duties, the lack of leadership on energy independence, the absolute failure to to secure the border from economic parasites and terror infiltration, or a failure to reform government entitlements and reduce the overall tax burden in order to reduce taxes?

If not, then your only concerned with the little R next to his name. And replacing him with someone with a little D next to their name is extremely counter productive.

#243 Re: Not So Free Chat » Oil Prices Surge to Record Heights - 90 US Dollars » 2007-10-30 07:11:39

Thank you Nancy Pelosi! roll
We really needed you to comment on the attrocities of the Turks against the Armenians right now, especially when we have troops in Iraq!

That must be what she was plotting in Syria a few months.

I'd change that to say:  all the world can think about is the end of the George Bush administration. What matters is that we survive any further faith-based insanities--not to mention loot--they may still be able to get away with during the remaining time left to them!

Halloween is tomorrow.

#244 Re: Science, Technology, and Astronomy » Is Earth the new Mars? » 2007-10-28 22:43:33

The real threat of climate change is not that the Earth will become a hot, barren desert. Its that it will disrupt the unusually (geologically) temperate climate the we have enjoyed over the the bulk of the history of human civilization. Whether this is our fault or not, or if we can even stop it either way is up for debate. Certainly there is much we can do to limit our contribution, but the Earth is more than capable of shouldering the load.

The inconvenient truth is that we may very well be on borrowed time.

#245 Re: Unmanned probes » Cavern exploration » 2007-10-28 18:25:37

#248 Re: Science, Technology, and Astronomy » Earth Death » 2007-10-27 20:57:39

If by death you mean devoid of life as we know it, it will probably be well before that, thanks to the Moon. As it continues to drift away the Earths axis will fluctuate wildly, killing anything dependent on a stable climate, and lengthening the day. Not long after that the lack of internal friction from tidal forces will reduce the spinning of the Earths core, greatly weakening the magnetosphere, and causing the atmosphere to be blasted away. We end up as a combination of Mars and Mercury.

Whats left will be vaporized as the Sun goes red giant. I don't know if Alpha Centauri going nova can cause that kind of physical destruction. But it certainly will provide an ample dose of gamma radiation.

#249 Re: Martian Politics and Economy » Land Allowance » 2007-10-25 12:51:17

Mostly because the Arabs have no idea what they are fighting for.

Actually they do. They are fighting to destroy Israel.

Thats why their Islamofasicst leaders send them into battle. But when they start getting slaughtered on mass for no apparent gain, they quickly realize they are wasting their lives and start retreating or surrendering on mass.

In disturbing opposition to this general rule, Hezbollah guerrillas have been practically bred for that purpose, and fought like in Southern Lebanon last year.

#250 Re: Martian Politics and Economy » Land Allowance » 2007-10-25 08:03:47

Mostly because the Arabs have no idea what they are fighting for.

I can't speak for all Soviet weapons, but the AK-47 and its derivatives are universally viewed as the most durable assault rifle mankind has ever produced. Thats one reason theres so many of them. The old ones are still around and work.
