Project Solar Harvest 
Presented at Island Earthfair, Vashon Island, Washington
(Exhibit Photo 1)


Double-pane windows admitted UV and visible light and served as modest insulation; 40 pounds of recycled metal converted the light to infrared energy (heat);  for storage the metal transferred its heat to the 20 gallon tank of water in which it was floating; the tank of water was somewhat insulated with 4" of newspaper.
