If anyone is curious as to why we don't run the world off solar, from what I understand the big issue is power grid frequency. Unlike a turbine, solar has no intertia. If you take away light the power drop is instant. With turbines, they keep spinning due to their weight. This is especially important since if a large load is suddenly energized, the turbine might slow down but still won't stop immediately. Maybe in the future giant electric powered flywheels or pumpgen systems can take up the slack. Nuclear would likely also help since those are essentially giant steam turbine generators. Good video with some more info here.

I would post that passage from Grapes of Wrath about oranges. But copy-paste doesn't work on my phone

Sounds like economics needs redefining.

Hear me out: a giant water balloon. Roughly the size of the sun.

Hear me out: pump the excess solar power from the sunny side of Earth via maser into space at a geostationary microwave mirror array that reflects and focuses power back at a ground station on the dark side of Earth.

Gemeni then said, "hold my beer" and proceeded to blacken the sky.

That's exactly why i want it, but i can't in our appartment...other than a single mobile panel on our balcony and a mobile battery, which will cost about €1000 and will only allow me to partially run some electric devices.

As a solar punk, I have solar panels, some batteries, and all my stuff runs off USB or 12v. I don't pay utilities

But we can start rejecting late stage capitalism. Unfortunately, that’s not what is happening people are voting for right wing nut jobs who will enforce capitalism through oppression, poverty, mass surveillance and militarized police.
