Massachusetts company plans to market wireless electricity system

@ 2009/12/05

A Massachusetts company said that within 18 months it will have on the market a wireless electricity system to power -- through the air -- lights, computers, televisions and even the chargers for electric cars.

The announcement was made at the TEDGlobal conference, a gathering of technologists and scientists, that wrapped up Friday in Oxford, England.

I don't think they can do much of anything. The efficiency of wireless power transfer falls off exponentially as the distance is increased, any sort of long distance power transfer wouldn't be strong enough or viable because of the efficiency dropoff.

A hdd is normally protected by it's casing which create a faraday cage. In fact, everything inside a pc is protected from incoming waves.
I just wonder how they are going to deal with regulations. Currently you can't even transmit 1W/m² without breaking regulations. How can they charge a car's battery at a reasonable rate ?

wireless electricity is still in the nascent stages. It has a long way before mass adaption can bring down the prices and perhaps force manufacturers to offer wireless power supply with the electronics they sell. This site has a a list of wireless electricity providers but most of them listed there provide only OEM support. - wirelesspowersupply.net

what about them?

what about AM and FM radio, HAM radios, walkie talkies, mobile phones, and television?

what about magnetism, magnetic hard drives and people with a pacemaker?
