Witricity was actually first observed in the 50’s but among its many problems was the unsafe factor. Having electricity carried through electro magnetic waves could be cause for nervousness or even cancer. Another major objection would be the theft of electricity through the wireless waves.
If you thought theft of broadband internet through wirelessÂ network cardsÂ was a problem you could easily surmise that theft of electricity would be an even major concern. Considering the fact that people pay a lot more per month on electricity you would assume there would be people stealing it via witricity wireless devices.
We will have to wait and see what may happen. For right now we can only guess as to what the risks might be.
