I am all for it. Anything that can increase large scale energy storage is helpful, and I don’t have to be a stinking greenie virtue signaler to benefit from it.
Sure, put one in my garage and when it’s charged by the sun I’ll use it to offset electric costs - IF it’s cost efficient
I like it, too. But I want it at a smaller scale so I can buy one or two for my house. Anytime the green energy is done by utilities there’s always a lot of palm greasing and inefficiencies and bureaucratic red tape.
