G+_Michael Heinz Posted June 10, 2015 Share Posted June 10, 2015 No because broadcasting power across an entire room is horribly inefficient. Signal power fades with the square of the distance - if you can draw 1 watt of power one foot from the transmitter, you'll only be able to draw 1/4 watt at two feet, 1/9th of a watt at 3 feet and so on.
