Tesla would be proud: Wireless power

For nearly a hundred years, people have been trying to make wirelessly powered devices and although there have been plenty of people to make fun of the idea, it seems it has actually become a reality. Above is a 10 minute video of a presentation showcasing the already developed wireless technology. It uses magnetic fields to transfer the power over short distances, and the presenter shows that it can work on anything from a TV to a cellphone. Best part is that he can walk between the transfer coil and the receiver without fear of negative impact.
