Seriously, I've often thought about how cool it would be to have wireless power but I'm not convinced it can be done safely. In order to transmit 110 volts across any distance greater than a few feet would require a pretty focused beam, and I would not want to stand in the way of that--magnetic field or otherwise. Also, to have something like a power station that broadcasts power in all directions would require a massive amount of energy, because most of the power would be wasted and not received by anyone. So, while the idea is cool, I'm going to bet against it being used for anything other than replacing batteries at very short distances for at least 20 years.
