Next Generation CPU Refrigerators

Iddo Genuth writes "Researchers at Purdue University are developing a miniature refrigeration system, small enough to fit inside laptop computers. According to the researchers, the implementation of miniature refrigeration systems in computers can dramatically increase the amount of heat removed from the microchips, therefore boosting performance while simultaneously shrinking the size of computers."

Re:How much juice?

Could be pretty damn efficient if it's a heat pump.

A good AC unit usually consumes less than 10 times the energy it moves (a 1 kW window unit rated for 40,000 BTUs for example), but that depends how much colder the inside needs to be compared to the outside air.

In case of CPU coolers (cooling things hotter than ambient air), one could even GENERATE electricity if the size and cost of the "cooler" is not a concern (A thick diamond heatpipe to conduct heat away to distant thermocouples is how I would do it).
