Make Your Own Solar-Powered Heater
July 25, 2009
This is just amazing. EcoTechDaily has just released annoyingly simple plans to make your own solar-powered heater. All you need is some aluminum cans, an old window, and a couple of tools.
The windowframe has holes on the bottom where air enters and one hole on top. You paint all the cans black, drill holes on the bottom of them, and stack them in the window as pictured. The hot cold air enters through the bottom, heating up tremendously as it passes from can to can (and as we all know, hot air rises). You can then direct the hot air into any room through a dryer vent or something similar.
When I first saw this, I thought it was too simple to work. But the author claims he got the heat up to 105 degrees!
I have no words. This is exactly the kind of innovation I love. Cheap and simple, so anyone can do it. The only drawback would be that the heater would only work during the daytime or when the sun was out, but cutting my heating bills in half doesn’t sound too shabby.
