They claim it’s safe and effective over long distances, I couldn’t find a definitive length over which it works.
The relays are essentially lossless. The loss there is almost zero. They don't require any power, you can think of them almost like lenses; they refocus the beam.
So there he admits the 30% transmission losses and tries to imply losses in the rest of the system are minimal. Well exactly how minimal? I'd say if he gets 30% loss in the transmitter and another 20% losses in the rest of the system that's feasible in certain circumstances, but that's 50% loss total, compared to say 10% loss with wired systems.
So the relays are lossless, what's the efficiency of the whole system like?
The efficiency of all the components we've developed are pretty good, close to 100 percent. Most of the loss is on the transmitting side. We're using solid state for the transmitting side, and that's essentially the same electronic elements you can find in any radar system, or even your microwave at home. Those are at the moment limited to around 70-percent efficiency.
we have a laser matrix, so we make sure that the beam always touches nothing but clean air. And even if we didn't use that laser matrix, you'd have to linger quite a while in that beam to get a little bit of heating effect, say one degree hotter.
So he's got a 2 KW test system, which by the way I get billed for about 1.9 kW when my 1.3 kW microwave oven is running, so just that one appliance alone uses almost 2 kW according to my electric meter.
The levels of density we're using are relatively low. At the moment it's about the equivalent of standing outside at noon in the sun, about 1 kW per square meter.
Obviously we'll increase that, but the levels of power density will still be quite low.
Kushnir claims the technology is scaleable to 100’s of times this power.
I didn't get any sense of any new or "early" technology from his interview, the same basic tech has been available for a long time, and I seem to recall making a post on ATS almost a decade ago about a company that already offered wireless microwave power transmission.

The technology is early though, and he claims is scaleable.

With no long conductors involved, geomagnetic activity would not be a problem. Transmitters themselves would not be directly affected and could be isolated from the problems involved with the low frequency fluctuations involved in the main lines.
But I can't see this system being used to transmit the amount of power transmitted by high tension lines. It seems of potential use much further down the distribution system.
