Solar-Powered Beer Bottles
Researchers at RPI have developed a thin solar cell and heat pump that could simply be slapped on a bottle of beer to keep it cool. It has no moving parts and can both cool and heat. Tempra Technology, meet your new competition. Of course, I’m guessing it’ll be years before we see a commercial product.
Actually, forget the beer. Just coat my body in this substance in preparation for hot weather.
