cylonlover writes “Traditionally, thin-film solar cells are made with rigid glass substrates, limiting their potential applications. Flexible versions do exist, although they require special production techniques and/or materials. Now, however, scientists from Stanford University have created thin, flexible solar cells that are made from standard materials – and they can applied to just about any surface, like a sticker. The cells have been successfully applied to a variety of both flat and curved surfaces – including glass, plastic and paper – without any loss of efficiency. Not only does the new process allow for solar cells to applied to things like mobile devices, helmets, dashboards or windows, but the stickers are reportedly both lighter and less costly to make than equivalent-sized traditional photovoltaic panels. There’s also no waste involved, as the silicon/silicon dioxide wafers can be reused.”

The Glassmap team thinks check-ins have peaked. It’s too much effort with not enough reward to manually share locations, and the resolution isn’t high enough. Check-ins are just sparse dots on a map. Glassmap wants to track its willing users constantly.
Glassmap was conceived at Stanford University, and 10% of Stanford undergrads are now using it. It has since rolled out to 10 other colleges, and Woo says it’s going well. A campus is a natural place for an app like this. “We just wanted to know where are friends were, where our roommates were, where the parties were,” Woo says.
