Now here’s a cool technology demo’ed at TED.
It’s based on the idea that electricity can be converted to a magnetic field that vibrates at a certain frequency. Anything that contains a corresponding electronics can be brought into that field, which causes that objects circuitry to also resonate with a matching magnetic field, which is then converted back into electricity.
Thus, electricity is sent wirelessly.
And apparently, it’s quite safe.
Of course, we’ve seen something similar in the Sonicare electric toothbrush, which has been out for quite a while, plus the Palm Pre recharges in a similar fashion. However, this new technology focuses on having a greater distance between the charging source and the chargee device.
Cool stuff.
