Wireless Electricity.

Wireless power transfer over two-meter distance, from the coil on the left to the coil on the right, where it powers a 60W light bulb.

A team of scientists from MIT demonstrated a way to send electricity through the air, without wires:

Realizing their recent theoretical prediction, they were able to light a 60W light bulb from a power source seven feet (more than two meters) away; there was no physical connection between the source and the appliance. The MIT team refers to its concept as "WiTricity" (as in wireless electricity).

    Uuummm… I hate to break this to these brilliant scientist but a Mr. Nicoli Tesla did this back in 1890. Maybe they haven’t thought about going to the library and reading something about the history of their trade.

    Hey! Maybe next they’ll devise some sort of round things that can be attached to an axle to allow man to move heavy things more easily. They could call it… Oh… Let’s say a “Wheel?” Duh!

    Who doesn’t know about Tesla? This would only be news if they were efficient. How much energy is lost in the transfer?

    I dunno somethin tells me this will just slowly cook you if you spend too much time indoors! dangerous for couch potatoes much?

    Steve’s right! Tesla did that a hundred years ago and even recently I’ve seen some geeky websites, where someone did this at home, so I wouldn’t say those scientists have done anything special..

    Cool! Dr Frazer Crane is on their team! Go Seatle!

    If the MIT kiddies didn’t know about or didn’t credit Tesla then they need to recieve the WORST GRADE IMMAGINABLE: AN A–
    (sorry, couldn’t keep from a Futurama reference…)

    Akk. Filters.

    That should be an A MINUS MINUS

    Wonder what the side effects are, standing between the coils like that.
    Maybe none of them wanted to have kids, anyway.

    I think thet they achieved an efficiency of 40% *(According to “Der Spiegel”), something Tesla never did.
