Make a Solar DS "light" that you will Never Need to Recharge Again!

The Nintendo DS Lite seems like it was made to have solar cells put on it. It has a large amount of surface area on the top and bottom that both face upward when the DS is opened.

Making and using a "compound" parabolic solar cooker (Large project)

Best shape for solar reflectors? Parabolic dishes to a point ONLY when they are pointed EXACTLY at the sun. But the sun moves and that point quickly spreads all over the place unless your are watching over your solar cooker all the time.
