New 3D CPU Water Cooling Method
captain igor writes "According to this story on Wired News, a new company launched by researchers from Stanford has come up with a way to layer a silicon network of tiny tubes on top of a microprocessor. The system then uses a solid-state motor (no moving parts!) to pipe cold water through the silicon network. According to the article, this system can handle 1000 watts (yes, a kilowatt) per square centimeter."
Forget about the cooling, tell me more about that pump! /me googles electrokinesis ..
apparantly it uses osmotic pressure to drive it, how cool is that?
A computer without Microsoft is like ice cream without ketchup.
/. is acting weird, so someone will probably have posted a similar idea, but ...
If you could figure out a way to sew this into material, then you could have some really "cool" (literally) clothing. I'm sure people like the Army would be very interested in a suit or body armour that offered effective cooling, esp in the desert where a system with a motor could be undesireable. I know it would be sweet to get a set of motorcycle leathers with something like this built in (those Texas summers get a bit toasty).
I wonder how long until we have nanotubes running all through the processor. There's a professor at my school doing research on 3-D photolithography, which would allow much more complex structures to be built out of crystalline silicon. This sounds like a good application.
This side up.
Actually, I wonder what the theoretical limit is on converting waste heat back into electricity in a laptop... would it be worth the extra weight? Even if it's NOT worth the extra weight, it might be fun to do it just because it can be done.
Off the top of my head, though, I'm not aware of any laptop-scale device for generating power from a heat source.
