in brief nasa as a cool new pump that super cool one side, much like a pelter but far more hard core and faster,

not all that much info about it, but a promising step

dumb question but since it's so cold in space, or so I'm lead to believe, would you require a heat sink on your computer in space?

i guess it would depend on where the computer is, outside will all those pesky bits of dirt and mirco meteors, or inside the crew cabin, no even sure about the dynamics of heat dispersal in zero g

at the end of the day i guess this will be lighter and smaller than 1kg of copper and six fans for a mega overclocked cpu or having a fire engine pump for a water cooler

so lighter and uses less power for better cooling, got to be a win, and just think if the battery cooling that could happen, smart phones the rock i7 type power, and under 300grams (massive pipe dream, but no doubt the power might be here with in 10 years)

depends where you are in space.. if you are in the shadow of the moon for example its very cold and during 'day' on the moon its very hot(i cant remember the temps and cbf searching) it also depends on how far away you are from a star.

Don't the laws of physics say you can't create or destroy energy, just move it around? So the colder you get the CPU, there's going to be something, somewhere that gets hotter. Right?

It's very, very difficult to cool things in space due to it being a vacuum. Without an atmosphere to transfer heat to you're only left with radiation which isn't as efficient. Though radiation works better in a vacuum compared to an atmosphere, it still isn't enough to close the gap between the two.

Yep. Right. Conservation of Energy.

Good question about cooling in space though. I don't know the answer.

The answer is that its very cold in space, but there's also not a lot of conductive material so hot stuff stays hot for quite a while even though the temperature delta may be pretty high.
