Holy Nikola Tesla! Researchers Wirelessly Transmit Power Over 98 Feet of Thin Air

Nikola Tesla is known for many things besides inspiring the name of an electric car company — the design of the alternating current (AC) electricity supply system and motor is perhaps the innovation that affects the most people to this day. However, his dream was to do away with the wires and distribute electric power wirelessly – his Wardenclyffe Tower on Long Island was perhaps the best-known monument to this unfulfilled quest. If Nikola were alive today, he would likely be excited about (and probably consulting on) a new system developed by researchers in South Korea to transmit electric power safely using a wireless laser. Does it work? How does a transmission of 30 meters (98 feet) sound? Will we get more use out of this than just wirelessly charging our cell phones?
