> so the 3.2GWh battery grid storage array, in operation, this is still 1/100th what is needed?

Unless I'm mistaken, the US consumption is 500GWh/day with peaks at 700GW/day, so 3GWh isn't going to do much

"This technology that is starting to emerge is garbage because it's not already everywhere"?

... and so we're back to my first comment, a 100x improvement is still needed for this kind of usage.

3GWh isn't even at a proof of concept stage yet for this kind of usage. Even 10x that would barely be called a POC.
