No details of input power to the transmitter nor power received by the receiver.
Companies have demo'ed similar devices before, but where the rubber meets the road is the efficiency and total power of the system. In other words, if it takes 200 watts to transmit and 200 milliwatts received at 3 feet, it is not useful for a consumer nor the environment.
