I don't see why they don't just attach the back of the solar cells to the wall of a cooling tube. This kills two birds with one stone. Water is heated, and the cells are actively cooled allowing use a of a higher concentration of light. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
