This guy has, and you probably could too…this is pretty cool. Looking for a way to heat up his garage workspace through the winter, Daniel built himself a free heater using soda cans, black paint, 2X4’s, plexiglass and some caulk. The unit sits outside his garage facing the sun, the soda cans collect the air and heat it up, and a hose leading into his workspace brings air in that is at least 15 degrees warmer than the outside air.
Brilliant, and I wish I had a space to try out building one of these.
