My experience with Cansolair | Alternative Energy | Forums

For any who may not know, Cansolair is basically a solar space heater built out of soda or beer cans. I learned about this a while ago and decided to supplement my home heating with a couple of units.

The Good:

Free Heat! It really works. It cranks out some nice heat, even warmer than my heat pumps!

It's Quiet, but loud enough to know it's working. Just a tiny fan pumps the heat out of the unit.

It's Simple! Really not a very complex unit. Not much to break or go bad, so I expect it to last a while. If you're motivated you can build one of these yourself pretty easily.. You don't have to be an engineer or mechanic to do so.

The Bad:

No sun... No heat... It works pretty well under mild cloud cover, but without sun this thing is not doing anything. Obviously that means no heat at night from these.

Any questions, lemme know!
