The potential of wireless charging created great excitement when it first came to prominence in 2007 when two researchers from the Massachusetts Institute of Technology (MIT) successfully powered a 60-watt light bulb wirelessly, using two copper coils two metres apart. These researchers went on to create Witricity, a company devoted to the technology.

Since creating Witricity expectations over wireless charging have proven over-inflated. However, Witricity believes 2015 may be a breakthrough for its “magnetic resonance” method, as it can transmit power as far as several feet and through surfaces like wood and cement.
