I was about to post nearly the same thing. As everyone familiar with electricity knows, induction's a bitch, and I wouldn't want to be somewhere near such a device once something goes wrong (just one example, imagine the flament in the lightbulb burning out slowly and flickering while doing that - in that case the receiver might become an uncontrolled sender due to back induction). Then there are things like cardiac pace makers, which are likely to be influenced by static magnetic fields when moving through them. It makes my toenails curl up when I listen to the overconfident proclamations that are spread now.
