Low-Cost Solar Heater Made From Soda Cans
Posted by Sonja Ebron
The green economy is here, and those seeking to profit from it must keep an ear to the ground for new business ideas. As a sign that green thinking has reached the grassroots, I recently found a Daily Kos diary describing how to heat your home with soda cans. The materials are easy to find at most hardware stores, and the process is relatively simple. This could be a great money-maker for an industrious entrepreneur with a little mechanical skill.
Here’s what you do:
- remove the ends of 240 soda cans,
- glue 16 cans together with caulk to make a column,
- repeat step (2) until you have 15 columns and let them dry for 2-3 days,
- drill 15 circular holes into two 2 x 6’s to make column manifolds,
- fit the soda can columns between the two manifolds,
- make a rectangular box with a plywood base and line with aluminum foil,
- place the cans and the manifolds inside the box,
- cover the box with Lexan sheeting and seal the edges,
- connect the columns with flex duct on the top and bottom of the box,
- attach some piping, an in-line fan, a thermostat and other accessories.
Despite all the high- tech research on new products to save energy and the environment, these are the proven, low-tech, low-cost concepts that will see most of us through.
