Wireless Electricity?
Last week, an MIT research team announced that it had juiced up a 60W light bulb using ‘WiTricity’, the name it has given a wireless electricity source it is developing.
The team generated the WiTricity using two copper coils, one attached to a power source. The power coil emitted a field of magnetism to the unpowered coil, stimulating it to generate a current that powered the light bulb from seven feet away, said Andre Kurs, a graduate student in MIT’s physics department who worked on the project.
