Infrared technology transfers power through light
beam using laser diodes. Powerbeam has developed kits
ranging from 100 mW, 2.5 W, to 10 W with range of
around 10 m [1]. This technology can work but has
serious limitations. First, it requires direct line of sight
(LOS) between the transmitter and the receiver, the beam
can be interrupted and can interfere with IR remote
controls. Lastly transferring more than 10W of power
with a laser can be very dangerous.
