"It turns out the human body is not affected by magnetic fields; it is affected by elective fields. So what we are doing is transmitting energy using the magnetic field not the electric field."

Magnetic field strength falls off as the cube of the distance. Therefore, in this age of skyrocketing energy costs I have to ask how much extra power this wirelessness requires. Does it take 120 watts to power that 60 watt bulb? What happens when you get more than one of these units operating in the same room? How does such a powerful oscillating magnetic field affect nearby objects, like hard drives and floppy disks?
