> system is planned to have two solar array wings of 2.2 km × 2.7 km each. It will use 4,000 sub-solar arrays of 10 m × 270 m, made out of thin film roll-out, with a system power efficiency of 13.5%
> On the ground, the researchers propose to place 60 rectennas with a diameter of 4 km along the Korean Demilitarized Zone (DMZ). In that case, 60 satellites will have to correspond to the 60 rectennas.
> “If each rectenna could generate 2 GW, the total power collected would be 120 GW, providing approximately 1 TWh of electricity per year.
This project would offer electricity to South Korea 24/7 and would cover almost 200% of South Korea’s needs.
The US was pretty gung-ho on this idea through the 70s, but the Reagan administration wasn’t a fan and canceled further pursuit of the concept.

So wireless power transfer?
I remembered my EE buddy talking about this in our college days. It is good we can finally see it on a large scale.
Big if true.
My wireless phone charger fucjing sucks and good luck if there is a case installed. Also you’re losing like 50% efficiency from wireless transfer of power, and that loss is in the form of heat… I can’t imagine the hurdles required to overcome in order to get anywhere near the projected 1TWh of electricity. What happens when NK accuses SK of „raising the temperatures“ and destroying their crops due to misuse of this project? Even though its climate change that is affecting NK.
What happens if the beam of energy being sent down hits a person or a house? Is this a dual use tech? Is it a power station and a space death ray?
