I mean thats a big number, but if you think about the amount of lakes needed to run hydro, its not actually that much of a number.

I'm not saying musk is a clever man for pointing this out. Even greenpeace said stuff like this in the early 2000s.

the point is, it sounds bigger than it is. For oil storage, the US has something like 36 square miles of storage (converting from cubic to square isnt accurate)
