Millions of homes could be powered by solar power beamed down from space by 2050
Government has commissioned a study to look into the economic and engineering feasibility of generating vast amounts of energy in space
I think Dave covered such subject before?

That's like building a Deathstar in our orbit. What a great idea!

5 bucks this doesn't work out :)

If you fill a couple 1000 hectares with rectennas you don't need especially large power densities.

To my knowledge there is plenty of solar power being beamed down on us already. Seems reasonably safe as long as you avoid overexposing your skin.  :P

Years ago, a rich guy posted a warning sign on his property:
"Danger!  Radiation hazard to unprotected personnel."
He explained to the authorities that anyone walking on his property stark naked could get a sunburn.

This was neatly covered in The Expanse (books and series) science fiction series. While probably possible, basically the orbital mirrors turn into convenient military targets. In this particular case over Ganymede, the outcome of which was massive amounts of destruction on the surface.

Start at 1:55 (or watch the whole damn series as it was quite good):

Indeed, just on a slightly smaller scale: IR wireless charging.

Reminded me of the science exhibit that sported a sign: Danger! 1 million ohms! :-DD

Whats wrong with a bunch of solar panels on the roof of my home???
Are we having a  crisis of not enough solar energy??
Its only like ~50% of the earth is exposed to the sun constantly..

Atleast with my rooftop solar panels there will be no transmission losses of the energy as with from deep space!  :-DD :-DD :-DD
If god made us in his image,
and we are this stupid
then....

And I thought sticking my head inside the microwave oven (after bypassing the interlock with a spoon) and then turning it on was dangerous!

You know, I love the expanse, it is a great sci-fi show, but...
Ganymede doesn't have an atmosphere, Earth does, so that mirror would burn up.
The whole "mirror falls down on the ground" makes no sense whatsoever. I get that it had to move the plot forward. The physics dont work out. If you break apart an object on orbit, you end up with a lot of object in orbit. Ganymede is tidal locked to Jupiter (just like our moon), so I dont think there is a geostationary (ganymostationary???) point for the mirrors. They are also enormous on the show, has to be several hundred km, if it is as big as they showed on the show and if it would be in orbit. I have to assume they are held in place with an Epstein drive, they are much closer to the ground. Which is a magic technology.

There was a whole argument about 1000 posts long on reddit about that and some actual physicists came to the conclusion that there would be a geostationary point around 46,000km up, which didn't make a whole lot of sense. I think everyone was too exhausted by the end of that to decided on the failure mode  :-DD

I agree though. In the case of Earth it'd make one hell of a mess destroying one and cause a massive debris field.

Still the point of science fiction is to make you think and it did that which is a winner  :-+

Agreed, great show, I'm watching it for the 3rd time.
Obviously, the UK needs a space elevator, with a giant solar windmill mounted on it.

There are actually 4 points in space that would be usable for such space mirrors around Ganymede - Lagrange points 1, 2, 4 and 5.

Does this technology mean solar roadways work at night?

What about tethering the Moon with a space lassoo, and then towing the flottila of mirrors in lunar orbit, just like kites on a twine? The Moon only makes one revolution per orbit, so no issues with tangling up the twine. Plus there is a ready 'elevator' for construction and servicing. And it would look nice too.

I imagine the mirrors would also have holographic logos etched onto them, so we could see which altruistic companies funded and built them...

My money is on the monoliths. Then we get two suns! Think of all that extra solar!
