Since the weather here is finally starting to turn cold I have been spending time searching for a way to heat the house. We have a little heater, but that only heats so much and it also uses a lot of energy. Luckily, I finally came across a great option, a solar space heater.
The idea of a solar space heater or “soda can heater” is to use the sun to heat up metals tubes and the air that passes through. They can be built for cheap, using a few supplies for a frame or even some spare materials. The metal tubes can easily be built out of aluminum soda cans.
