MIT Researchers reported last month that they successfully “beamed” a steady current of electricity to a lightbulb over a gap of 2 meters. Based on work imagined yet never produced by Nikola Tesla in the early 1900’s, the practical applications of wirelessly transmitting large amounts of electricity are endless.

Soljacic’s wireless power system harnesses oscillating electric and magnetic fields in a novel way. Although it doesn’t radiate energy as a radio antenna does, it transmits power across greater distances than a conventional transformer can.
