Power Relay Technology utilizes light to transfer high power over long distance using a small footprint receiver.
Wireless Power is typically found on phone charging pads and more recently in experiments powering EVs. As the world becomes increasingly electric and automated, wireless charging will become more common. There are a few major challenges facing the wireless transfer of energy. In the case of inductive charging the major limitation is distance. In the case of RF (Radio Frequency) wireless power, the limitation is high power with high efficiency using a realistic receiver size or footprint. Both technologies have legitimate tradeoffs.
