The Star Wreck trailer looked terrible, but this one created an interesting enough mood with it's music choice that I might actually watch it. Certainly more interesting than the average made-for-scifi-channel movie promo.
... The heat is going to flow across thermal conductors according to physical laws regardless. The only thing that this cooler does differently is it harnesses a portion of that flow for mechanical work rather than simply allowing it to distribute evenly across the heatsink. Unless I'm missing something, however, it seems likely that the fan will run slower the longer the machine is turned on, since the distribution of heat will gradually reach uniformity across the mechanism, at which point you no longer have a source of useful power.
The device has to first decrease the flow of heat so it can extract useful power; then it uses this power to drive then fan which increases the flow of heat. The question is, can the increase be larger than the decrease?
I say it can't because if it were, we could siphon off some of the useful power, slowing down the fan until heat was flowing at the same rate as before the device was turned on. Now the "outside" of this system is outputing the same amount of heat as the original source, and we can repeat the procedure arbitrarily many times: hook up another such cooling device to the outside of the previous and extract more useful power. Thus any source of heat is a source of infinite power!
But wouldn't it cool the chip faster if the heat wasn't having to push the fan? This is like using a waterwheel to pump water downstream. The inherent inefficiencies in the system would make it worse than just letting the water flow naturally. I'm almost certain that the device would be more efficient if you cut the wires to the fan, at which point it'd just be an expensive heat sink.
Now, if you wanted to use the fan to cool another component that needs the cooling more, then this might be a good idea. Then (to extend the above metaphor) you'd be using a waterwheel to pump water out of a mine so the miners don't drown.
I had been running 2.6.19 for over a year now, waiting for unionfs to make it into mainline so I wouldn't have to manually apply the patch. Turns out that doing so is pretty easy. And then the diff (for the actually exploit patch) on my distro's bug site had the line offsets just a little wrong for my kernel version, so I edited splice.c by hand.
So now I'm running Linux with a hand-patched kernel and lamenting what a gigantic nerd I've become.:-(
But, the whole reason to GO to a University, is to get the skills/education to make more money when finished, than you would have if you had not gone.
College is a means to an end. Money is a means to an end. Maybe you want to put your (possibly future) kids through college, or pay some horrendous medical bill, or maybe something else entirely. But you shouldn't assume that money is going to solve ALL your potential problems, and thus not set any actual goals in life.
I don't think money is as effective as learning in providing me satisfaction. If I could, I'd remain a student forever. In the Real World, I have to do something productive instead of just acquiring skills that could theoretically be productive (all MTV jokes aside).

No, that'd be (10^6 feet)^2 = 10^12 feet^2 = a trillion square feet. This would be better described as a (kibifoot)^2 = a mebi(square foot).
