The main idea of this project is to collect or trap heat from the sun into the soda cans. The warm air trapped into the cans are then channeled into the place requiring the heating through a very basic physical principle; colder air always displaces warmer air upwards. This way the warmer air is guided by the air tubes upwards and into the garage or living space then needs the warmth.
The interesting thing about this version is that it was put together by Daniel Strohl, a man with no expertise in the field of thermodynamics but rather is that this system was made possible by just following the advice of his father.
- Lots of empty soda cans
- Drill and bits (or a Dremel)
- Black paint
- Wooden box or an old sliding door
- Shop vac tube
- Drill holes through the soda cans
- Paint them black with BBQ black paint
- Build a frame (wooden and airtight) for housing the cans
- Stack up the cans on each other with adhesive caulk
- Attach a wet-dry vacuum tube to the top and bottom of setup
- Place outside facing the sun and channel the wet-dry vacuum hose from top of setup into the living space (garage in this case) requiring the heating
A fairly easy and straightforward way to getting upwards of 80F of heating in the cold. There are a couple of ways to improve this system so you can visit Daniel Strohl’s post on hemmings.com to learn more.
