Space-radiated cooling cuts power use 21%


Using the sky as a free heat sink could be a solution to an impending energy crunch caused by increased data use. More data generated in the future will require evermore electricity-intensive cooling — the data centers will be getting bigger.

Researchers at Stanford University think they have a solution to cooling creep. They say the way to reel in the cost of getting buildings cold enough for all the servers is to augment land-based air conditioning by sending excess heat into space and chilling it there.

The scientists say cost savings will be in the order of 21 percent through a system they’ve been working on, and up to 70 percent, theoretically, by combining the kit with other, newer radiant systems, according to an article in IEEE Spectrum this week.

Also, by beaming heat into space with specialized optical surfaces mounted on roof panels, entire buildings could be cooled without using any electricity at all, they claim.
