What do hexbears think about pumped hydropower storage?
(hexbear.net)
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. 
Okay okay, this off topic but
We should like build more molten salt nuclear reactors or something, they're so cool
Or maybe some of those
bed reactors
So many options for nuclear reactors these days
We will definitely need a variety of different power sources
Natural gas? 💨
China trying I guess? They are more invested in fast reactors and light water reactors and see them as purely experimental considering what happened in Germany with the THTR.
