Indeed, this new cooling technology does use electricity, it just uses a lot less electricity per degree of heat removed from a system. The technology is based on a magnetic heat pump instead of an electric heat pump. The good news is that the magnetic system is completely silent and uses 60% less energy. The bad news is that it's much more expensive to create and can currently only cool a system about 10 degrees cooler than it's surroundings.
That's bad news if you want your house to be 70 when it's 90 outside. But the researchers at the Technical Unviersity of Denmark are working on the problem, and say they will have a working (though certainly expensive) prototype in 2010.
