I guess this falls into the “What will they think of next?” category. A company by the name of Greendix has developed a solar panel in the form of a “frame” that can fit around touch screens of all sizes. The solar electricity generated by the frame will add to the battery life of devices ranging from cell phones to GPS units to laptops, and more.
It seems that solar technology is popping up everywhere these days. Of course we’ve had solar powered calculators for years, and I recently saw an ad for a solar powered computer keyboard. But now we can expect to shortly be able to harness the virtually unlimited power of the sun to help keep our tech products running ever longer!
