>Japan’s plan to supply all the world’s energy from a giant solar power plant on the moon
>Shimizu, a Japanese architectural and engineering firm, has a solution for the climate crisis: Simply build a band of solar panels 400 kilometers (249 miles) wide (pdf) running all the way around the Moon’s 11,000-kilometer (6,835 mile) equator and beam the carbon-free energy back to Earth in the form of microwaves, which are converted into electricity at ground stations.

So how is this different from simply building solar power collection plants on Earth?

Seems a bit troublesome to build a huge structure all over the Moon. I think it would be more viable to build it on one asteroid and put the structure in geostationary orbit in such way that you can point it always tot he same point.

the energy is still being beamed back to earth however, so it does have to penetrate the atmosphere.

I suppose they could convert it to longer wavelength so it penetrates our atmosphere easier, but microwaves are not very good at that.

1. Because microwaves aren't blocked by clouds
2. Because you can get microwaves in a frequency that won't affect the atmosphere/burn birds/bugs/planes.

But they should make a satelite instead

Wut? Microwaves HAVE longer wavelength than any visible light, even infra-red is shorter!

But what if from time to time one of the rockets crashes? And those meteorite impacts are indeed likely to happen. Oh, those unfortunate maintenance men who were just in it for the money, and their poor wifes and children. Nobody can help them while they're up there.

A)Accidents happen in alot of lines of work. Id hazard to say that the risk from rocket crashes or failures is less than the risk involved in working on a high seas fishing boat.
And B)
Cmon now. What are the odds a small rock will hit a man sized target over a landmass we can see as a large sphere in the sky from earth?
There are ways meteorites could be protected from too.
How hard to they tend to hit the moon, again?

If Japan ever manages to do this, it's not going to be used to power Earth. It would be much more useful to use the power to mine and process moon materials to build a large moon colony or space port. But don't tell the Japanese that. Let them find out after they accidentally build us a space port on the moon.

Geology nerd here.
This is impossible with current solar panel techniques, due to the high amount of rare earth elements photovoltaics require. Unless you build a reflective, working material plant. Which could feasibly work but you can successfully build those on Earth, people are just stupid and think they're ugly. We now have solar power which can create energy 24 hrs a day
