To make solar power viable, we need a solution for overnight energy storage.
Batteries are complicated.
Do you know what isn't? Water go up.

What about a weight and a skyscraper?
Explain.
Freight elevator shaft (boring, no one uses anymore), biiiiiiigggg grand piano, cartoon cat on massive, convoluted, downward-sloping treadmill
Don't worry he likes it :3
Will his teeth turn into piano keys following the imminent collision? What song will they play?
Can't play ragtime on piano teeth anymore, because of woke
Unsure of the details, still waiting for my grant to get approved
Ideally we would avoid collisions cuz its unpleasant for everyone involved, especially the cat
Would set it up at the end so he narrowly escapes
The amount of energy stored from raising a very heavy block up is not that much.
About 7kwh if you replaced an elevator with a block of lead in a 10story building
So yeah not much
