content: Hi, im an electronic engineer. Here's a few things about wireless energy: If there isn't a receiving antenna, made of metal, in a very specific shape, pointed to a specific direction. The energy from the transmitter doesn't leave, it doesn't go anywhere.  The shape must be of a coil, with very many and tight windings, something not usually found in the human body. If a recieving antenna is not present, the transmitting antenna doesn't even emit power, as it wouldn't have a path and would cause electrical losses (in the form of heat). To keep the thing from burning, it only emits the signal when activated by the presence of an rfid. But even if it was always on, the human body cannot receive this energy. This is physics, meaning, not disputable. But, lets say you've got a titanium hip replacement. There's a tiny tiny spring inside and it's pointed towards the transmitter,  the other end of spring is not in contact with the hip chassis, but is inside flesh, presumably a malfunction, a painful medical error. Let's also assume the transmitter is also dysfunctional, and is always on.  Now you can get cancer.... but if never charging my car or phone means you get cancer, i do not care about your cancer.
