Why would you crush your empty pop or beer cans with your foot or even your head when you could lug out a device that’s 30x the size of the can and probably use more electricity than the actual cost of the can? Because you can, that’s why.

By using a high voltage source and some large capacitors you can build your very own electromagnetic can crushing machine. Just remember that this is extremely dangerous. You are talking about an insane amount of electricity that’s flowing here and it will definitely kill you if something goes wrong. If you choose to not heed our warning and want more info on the project then you can visit Bob Davis’s blog, the creator of the device.

This is an ingenious idea. Used old pop cans to heat your house. The Pop Can Solar Heater is a simple idea and will work quite well to heat your house. Plus, a lot of the content is recycled so your helping the environment as well as your pocket book.

” The Cansolair Solar Max 240 consists of a four by seven solar collector (28 Square feet, or 2.6 square meters). Solar Max 240 has 15 vertical columns of cylindrical shape, making the actual surface exposed to the sun greater than 2.6 square meters.The same cylindrical shape allows the Solar Max to receive solar radiation for a longer period due to the angle of incidence of the sun hitting the solar panel. Peak BTU performance was observed during the noon hour period in October 2001 wherein the temp rise was 50 to 54F degrees resulting in a 9000 to 9720 Btu or 2636 to 2847 Watts. Peak BTU performance will actually increase in colder weather due to the rise in temperature between input and output temperature and a lower angle of incidence. The Solar Max 240 has a quick response rate of 8 minutes from the appearance of sun to “cut-in” based on 100 degree F output temperature. Solar Max 240 uses the most conductive black paint available for solar collectors. Solar Max uses a lexan outer cover which allows sunlight in and is resistant to the elements.”
