EEVblog #1092 – Wi-Charge IR Wireless Charging – Fact or Fiction?

Running the numbers on the W-Charge Infrared laser wireless charging system, does it work?, is it practical?, what is the efficiency?, how much power can it deliver?, is it dangerous?
And the laser power is HOW MUCH?!

CORRECTION: The laser output power was stated incorrectly, it was assuming the input power to the laser when it should have been the optical output power. The correct number for a 45% solar cell and zero other losses is 11.1W laser power, not 18W. Still the same class of laser and just as dangerous.

In response to the Linus Tech Tips demonstration.
Also some talk on the Energous RF Wireless energy boondoggle.
