Some Canadiens have developed a nifty device that basically just uses a fan to move air and a panel to build up heat. The panel apparently consists of soda cans painted black. It's a little more complicated than that as the unit is outfitted to turn on and off automatically, etc. But it's definitely something innovative and simple, and doesn't take a lot of sunlight to heat a good 1,400 square feet. Too bad I can't stick one of these on the outside of my apartment, it'd save some money in the winter.
