What do you think? Is it feasible or bullshit?

So a water tower, but underground.

Squishy Tower Power

D:

yea kind of, but you get A LOT more energy per unt of volume

Hay guys, all we need is a battery easily 10 times the size of the city!

"new", "crazy"

I've been telling that for years.

Yay, this is bullshit, there are better ways.

Wouldn't pumping the water up to the city use any energy that was created by it flowing into the tank?

>new idea
It's been around forever you fucking retard. My dad worked on one in the USSR back in the 1970s for fuck's sake.
