DEVap – 90% More Efficient Air Conditioner


DEVap cooling system

The National Renewable Energy Lab has Done It!  As Lloyd and other sensible people keep pointing out, if our buildings and cities were better designed, we would need a lot less air conditioning, and in many cases none at all. That should be goal #1. But because it’s doubtful that’s ubiquitous A/C is going away any time soon, it can’t hurt to make the technology more efficient (keeping buildings cool is using about 5% of the energy used in the US). That’s exactly what the engineers and scientists at the National Renewable Energy Laboratory (NREL) have done.
