You're right; Although the article doesn't discuss it, the challenge that must have been overcome in order to get this working is the dispersion of the heat. 10 times per day is actually impressive considering that in most other designs a side effect of launching a railgun projectile is severe heat damage to the rails and projectile.
From wikipedia - the heat generated from the propulsion of the object is enough to rapidly erode the rails. Such a railgun would require frequent replacement of the rails, or use a heat resistant material that would be conductive enough to produce the same effect.
So I'd like to know - do they just plan to carry a bunch of extra rails, or have they developed some material that conducts electricity but not heat?

Actually, the money invested goes back into the money supply as well. Either it goes to a bank account which then represents more funds the bank has available to lend out as loans for construction, business loans, or anything else. Or, if it goes towards an investment like a stock purchase then the other half (the sale) of that transaction represents someone who now has an equivalent amount of money to use to purchase goods or invest. The only ways for an individual to take money out of the money supply are to 1) stuff cash into his mattress or burn it or 2)send it overseas or use it to buy imported goods. (But even buying imported goods keeps a portion of the money in the local economy due to retailer fees, shipping fees, tariffs, etc.)
If it's ice, its not flowing. My point is you can have it flow and evaporate, but you can't have it flow and sublime. So if you want to say it sublimes, then how can you say it flows?
The liquid state can be defined by the ability to flow. So if it flows, it's a liquid and therefore it evaporates. If it is not a liquid, but rather is solid ice, it cannot flow. It cannot both flow and sublime.
From your frame of reference, the pain would be instantaneous before you were destroyed by the black hole. From an observer's frame, it would appear to take you an eternity to fall into the black hole.

Attaching a thermovoltaic device will just cause the fridge to work more to reject a given amount of heat, and, ideally, the amount of work extra will be equal to the power generated.
Sorry, you are wrong here. What if instead of using the waste heat to create electric current, you were using the waste heat to heat your coffee? Would that also cause the refrigerator to work harder? No. Thermodynamically, you can't distinguish between the uses of the waste heat. Exactly what is the mechanism by which the hot coffee would make the refrigerator work harder? The refrigerator would have to work harder in cases where the external temperature is high because the radiator has diminished ability to pass its heat to the surrounding air if the air is already the same temperature as the radiator. Putting a cold coffee cup in the radiator's environment will suck heat from the surrounding air and actually make it easier for the refrigerator to operate while heating your coffee. If you disagree, please explain in terms of scientific concepts.
If you think he is wrong please explain why.
I certainly think there is an opportunity here, not in the sense of energy generation, but for energy reclamation. The suggestion was to install sterling engines on heat exchangers the same way we install electrical generators on "hybrid" cars today. The point is to reclaim some of the energy that is passed through the device and wasted. In cars, it takes energy to get the car up to 50mph. Slowing the car from 50 to 30mph creates energy. In non-hybrid cars this energy is released as heat (friction with the break pads). Using the gp's idea, you could attach a sterling engine to the break pads and charge the battery with the electricity generated. It just so happens to be more efficient to use an electro-magnetic dynamo to slow the car and create electricity. Are you saying that this is impossible?
In a computer or refrigerator there is no motion, so the way to regain waste energy would be through use of a sterling engine. It probably would not be cost effective given the price/efficiency of the engine but it's a great idea and I think we will see this type of thing pop up more and more. The idea would be that your heatsink would have a power line that would connect to the power supply but instead of draining power would actually feed back into the power supply. Of course you couldn't expect to run your computer solely on that source of energy - that would violate the 1st law of thermodynamics and be equivalent to a perpetual motion machine as you implied. But get used to the idea of regenerative braking and other forms of energy reclamation - you will see an increasing number of applications of the concept in your lifetime.
Did I hear a moron completely misunderstand the meaning of "30% tax hike"?
Let's look at it this way - the article states $120/5 story building. Lets assume a very conservative 5 people per story per building. My salary is $60,000 and I pay about 28% income tax. That's $16,800 in tax.
$120 / building x 1 building / 25 people = $4.80 / person
($16,800+$4.80)/$60,000 x 100/1= 28.008%
So for my (fairly average) numbers the tax rate would go from 28% to 28.008% .008/28 *100/1= 0.0285714286
Resulting in a tax increase of less than.03%
You estimate a 30% tax increase.
30/.03 = 1000
You were off by a factor of 1000
Stay the hell away from my city and don't vote in any national elections you stupid arrogant asshole.

Did you read the parent? For the part just inside the atmosphere, how will you keep it aloft? By hot air balloon? If so, why not just attach the payload to the hot air balloon? For any method of keeping the non-orbital lower section aloft, you might as well just attach that lift to the payload directly.
TakeTwo can't appeal this order forcing them to turn over the game
That doesn't mean they have to turn over the game. They can simply refuse and then deal with the consequences. One possible consequence could be that the judge decides for the plaintiff. Then TTWO can appeal on the grounds that the judge's request for the game was unconstitutional.
Another possibility is that someone gets locked up for contempt for not providing the game. That can also be appealed on grounds of constitutionality. Either way, its not like TTWO is without options. It may be easier and cheaper for them to just hand over the game an appeal later, but they could also take the high road and protest the intrusion by refusing to hand over the game.

Good point. In my 7th grade class we learned that good goals are S.M.A.R.T
Specific
Measurable
Accountable
Realistic
Time-bound
The Bush Administrations goals seem to be
1)Bring freedom to Iraq
2)Stop Terrorism
Even a 7th grader should be able to tell that a better set of goals would be (for example):
1)Hold Iraqi representative election by December 2005; Withdraw all but 10,000 troops from Iraq by January 2008.
2)Implement 9/11 commission report recommendations by Jan 2007.
But yet we have no means of measuring whether we are succeeding at our objectives because SMART goals "emboldens the enemy"
Yes, price will go up. Supply of oil will go down nationwide, while the demand will stay the same. However, it is important that we are taking about National companies paying the tax. The increase in price will be paid by American consumers, not just Californian consumers. It is not a closed market. It is not the case that the oil drilled in California is the only oil sold in California. It is not the case that only Californian oil is sold in California. Nationwide prices go up. California prices stay the same. In the national sense, it is a tax that the American oil consumers pay to the citizens of California for the privelege of using the oil from their state.

What are you talking about? The question was whether Iraqis support partitioning the country, not whether its existence is natural...
Most [Iraqis] would be perfectly happy fragmenting [Iraq] along ethnic lines
1) I need to see some data to support this before believing it
2) Why doesn't this data exist?
