Engineering360: "Laser-based wireless power transmission"

What is the energy efficiency of the wireless power transmission line in New Zealand?

I hope its better than 10%.

"According to [Greg Kushnir], the founder of Emrod, the technology is about 70% efficient..."

This is a prediction, not measured. I think they only have a small model working. It depends on the efficiency of the components, range, how much of the beam is captured at the receiving end. I suspect it's not competitive with wired power transmission except in mountainous terrain.

They want to transmit power wireless? Tell FBI, or CIA, or NSA, or other deeply secret agency, to dig up and give back Nikola Tesla writings for his invention for free and wireless energy!
