Nanosolar wants to create paper-thin, flexible solar panels that can be made at 1/3 the cost of heavy, silicon-made solar panels.  It’s important to keep an eye on tech like this because Nanosolar is currently building the largest solar panel manufacturing plant in the U.S.  If successful, this stuff is going to be on every building and structure starting in 2008.  It’s going to change the way the game is played in a major way. 

To give you an idea of how compelling, how enormous this is, check this:  the Google founders are investing in Nanosolar, an IBM manufacturing executive just joined Nanosolar, and the U.S. Department of Energy just awarded them $20 million.
