HOW TO BUILD A SOLAR PANEL USING CANS

                   LEARN  HOW

                                The solar air heating collector uses recycled aluminum soda pop cans for the absorbed. The pop cans have the tops and bottoms drilled out, and are assembled into vertical columns that the air passes through. 

In operation, the black painted soda pop cans are heated by the sun, warming the air that is flowing up through the cans.                                                                                             

                                         More Info A manifold at the bottom evenly distributes room air to all the can columns, and a similar manifold at the top of the collector collects the heated air for distribution back to the room.    

The combination of uniform air distribution to the whole collector and the large amount of heat transfer area from the cans to the air makes for an efficient collector. Greg's collector also uses Twinwall polycarbonate glazing -- this is a type of double glazing that reduces heat loss and increases the efficiency of the collector   Can You Be Creative 

New Solar Panels That Work At Night

New Solar Panels That Work At Night                                Solar Energy Now            The scientific principle isn’t a new one, but the manufacturing process that maximizes efficiency certainly is state-of-the-art. The innovation within nanotechnology is what has allowed the nanoantennas to be efficiently embedded to absorb energy in a flexible and inexpensive material. Just imagine the possibilities… More Info           The technique involves the embedding of square spirals of conducting metal onto a sheet of plastic, each of which, referred to as a “nanoantenna,” just 1/25 the diameter of a human hair. The nanoantennas absorb infrared energy, which is absorbed by the earth during the day and released even hours after the sun goes down. The nanoantennas are thus able to harvest energy both during daytime hours and into the early evening. Because they can take in energy from both sunlight and the earth’s heat, the nanoantennas have a much higher efficiency (and potential applicability) than conventional solar cells.
