It could conceivably, if it works, meet South Korea's energy needs and possibly have excess to sell.

4,000 arrays of panels measuring 10 x 270 meters is pretty big. It is gonna take a lot of carnival balloons to float it all up there.

Focusing all the energy to small targets on earth — what could go wrong.
Sounds like something out of bond — James Bond.

>> It is not derived from rigorous analyses but rather serves as system requirements for commercial viability.
...wait, what ???!?
>> On the ground, the researchers propose to place 60 rectennas with a diameter of 4 km along the Korean Demilitarized Zone (DMZ).
Oh. It’s in Korea. What could go wrong? Go for it! I ain’t gonna pay for it though.

Don’t microwaves cook things with water in them, like people. What if someone were to hack the system and point it at Seoul?

I believe a space project could produce the electricity. Big whoop. Demonstrate how the power gets to the ground. I’ll wait, but I won’t hold my breath.

Maybe it’s not concentrated enough to do that? Being a km wide beam, it’s not like a laser.

Isaac Asimov wrote about this. I’m sure he didn’t invent the concept.

The power gets converted to microwaves and then is beamed to the ground and then, on ground, it gets converted into electricity.

The South Koreans are nothing if not ambitious.
There is the little problem of transmitting the power collected in space and getting it to the ground. A tight microwave beam, perhaps? Or the longest transmission wire ever built, stretching from the surface of the earth out to geosynchronous orbit? What about earth shadow, or a total eclipse by the moon of the array?
Reliance on thorium molten-salt reactors seems to be a better all-around answer, but perhaps there is a lot of money in South Korea for these kinds of research grants.

The advantage, according to the article, is that it’s cheap. 30.03/kilowatt. Another advantage, if it works as theorized, is that cloudy days won’t inhibit the productin of power because microwaves will beam through clouds just find, even if there is a bit of loss from rain absorbing the microwaves.
I’m sure they would keep back-up options in the event of a strike by NK or eclipses and what not. A combination of everything is probably what will work.

And if one of those transmitting satellites’ beams drifts a few thousandths of a degree, they will set a Nork guard post on fire.
Talk about dual use!
