Parent didn’t say develop, they said use. 80 acres of forest can be used as open space and not developed at all.

I think the spirit of parent comment was that if you have 80 acres of forest, but you live somewhere else and never set foot in it…well, maybe that land could be better used/enjoyed.

If you live on/near it, and enjoy it for some purpose other than strictly as an investment, that seems like you’re utilizing it.

200MWh is about 1/100 of Little Boy, the atomic bomb dropped on Hiroshima.

Compressed air can get out all at once given the right circumstances.

Storing energy in a way that can go boom is something I’d be a little scared of, were I a nearby resident. I’m sure thermal batteries can have gnarly failure mechanisms but I would way rather live near one of those than a giant compressed air cylinder.
