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?!

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