That's in Brazil, though? What do you mean it exists. High speed rail exists in China, I've been promised it since early 2000s in California and yet...
What do you mean by dispatchable generation?
Thousands of charge cycles means a few years? 2000 days is just 6 years
It's not going to support 100% renewable usage. It is not built to transfer solar power from Nevada to Minnesota
Everything works better when you have baseline nuclear power, transmission losses decrease, storage costs decrease, coal and gas get phased out. Remember that batteries need to be replaced often and they are very much not green. Nuclear plants operate on the scale of decades before getting replaced.
Storage costs balloon when you go full renewable, because instead of just storing enough for the night, you need to charge up enough during the summer to last the winter since solar power dries up.
Having a constant 20% of power nuclear would decrease the need to make a huge amount of batteries, since you can serve the demand on a lower amount of sunlight.
But what about wind? It works in places that are windy and have space for it, and America doesn't have super high voltage transmission to cover every area.
You just can't connect everything to shore up needs of every area because the country is too big and we forgot how to build things
But I still don't understand why people didn't Luke them. They were a more immersive experience
