While the run-of-the-mill solar panels need direct sunlight in order to generate a good amount of power, scientists in Jerusalem are working on colored panels that can make use of diffused light. The new panels are made with fluorescent dyes and nanoparticle metals and look a bit like colored plexi-glass.  They would be much more expensive that normal solar cells, but they would not have to rely on only direct...

With bulky solar panels being not only obtrusive but also pretty expensive, even if Wal-Mart did buy some, a group of engineers at the University of Texas at Austin have a better idea.  Spray-on solar cells. Chemical engineers at Austin's univerity are working on developing a spray-on version of solar cells that would energize surfaces and take the place of the bulky solar panels.  Here's wishing the group much success and we can't...
