Good Evening SuperForest,
This morning, SuperForester Jackson informed me of an amazing heater a cool cat crafted out of simple materials including an old window (with the glass still intact) and a few soda cans. A soda can heater!? That’s insane!
And what a beauty! Alright so first let’s take a look at the materials. If you want to try making your own, you’ll need…
- One old window frame w/glass intact
- Empty soda or beer cans, spray painted black, with holes drilled in the bottom
- Duct tape
- A piece of insulation
- Plywood for the back
- A dryer vent to hook to the top to direct the heat where you want it to go
- Small screen to cover the 2 intake holes at the bottom
Easy enough, right? You don’t have to go through a lot of trouble to find this stuff. The way this contraption works, as described by the maker, is…
As air enters the 2 holes on the sides near the bottom, the sun is heating up the soda cans all painted black to absorb the heat. The cans have holes drilled in the bottom, so the air being drawn in at the bottom works its way through all the heated cans and gets hotter and hotter as it approaches the top. With convection, more and more air is drawn in through the bottom and the heat rises. A single hole drilled in the top of the frame is where all this heat comes out, and I have to tell you – it’s friggin’ hot and it comes flying out of there at full speed.
Awesome! Now, I know it’s really hot out almost everywhere right now, and the timing for this is off by a few months, but it could still come in handy. You could even add a water element and make a some sort of sauna out of these windows, for example (lol!). The opportunities are limitless, and come on, how many people can say they built a solar powered heater out of their own two hands?!!!

Love to all,
