Wireless Electricity – Demo

Another cool video from TED. Eric Giler demos wireless electricity. Electricity can be transmitted wireless via resonance. It is not induction like in electric transformers. In this video he shows how a TV or cell phone can be powered wireless.

I think we all would like to get rid of wires. Wouldn’t we?  As of now this technology is not available commercially. Dell recently introduced their Z series laptops which can be charged wireless but it uses induction technology not resonance. For induction to work device should be in physical contact with the source. For Dell Z series laptop the laptop is charged by it’s stand which is the source. You might have seen similar induction technology used in tooth brush or electric shaver chargers.

    Wow… Imagine like this life style? I wonder if flying cars came to real. It would solve the problem of getting suck wires. And also have benefits to our environment.
