WiTricity: Look, mom, no wires!!

Tesla had a vision of distributing cheap, wireless electricity for everyone. For a long time that vision was buried, but researchers at MIT are digging to find the technology to make the vision come true, wireless electricity.

Researchers at MIT have shown that it's possible to wirelessly power a 60-watt lightbulb sitting about two meters away from a power source. Using a remarkably simple setup--basically consisting of two metal coils--they have demonstrated, for the first time, that it is feasible to efficiently send that much power over such a distance. The experiment paves the way for wirelessly charging batteries in laptops, mobile phones, and music players, as well as cutting the electric cords on household appliances, says Marin Soljačić, professor of physics at MIT, who led the team with physics professor John Joannopoulos.

SustainaBee says: This sounds great. Although this technology is still far from mainstream, these folks at MIT made a promising step! Hopefully research on this continues!
