beer cans heat up the solar scene
there is a solar fad raging like fire across the united states and beer cans are the main component. washed and black-painted beer cans are being assembled together to create solar home heaters. this video shows a personal solar home heater created from a bunch of beer cans, wood and some foil-backed sticky tape. i would setttle for mirror heating myself, but beer or soda cans that can produce up to 175degree temperatures is certainly a fun alternative.
