A group of Microsoft researchers has built a prototype charger for smartphones that can scan a room until it locates a mobile device compatible with the system and then charge the handset using a light beam (http://www.computerworld.com.au/article/564178/microsoft-researchers-use-light-beams-charge-smartphones/). The researchers say they can achieve efficiency comparable to conventional wired phone chargers. The biggest barrier? Smartphones don't (yet) come with solar panels attached.
