Looks cool. How well those aluminum foil work to reflect solar power?
 
This stuff probably works a lot better than the available and cheap mylar film (what shiney balloons are made from). But, the mylar is so cheap, I have seen pics of an 8' abandoned satellite dish that was covered with it. Once pointed at the sun, a piece of wood held up to the focal point burst into flame.
