Finally, I see mention of the HVAC "battery" idea I've been flogging for years. Progress!

I hope this progresses to using the pile-of-rocks "battery" to store heat/cold in cheap hours and draw on it in expensive hours.

It was popular in the 1950s. Deployed near where you live, even.

I know Seattle has an old steam plant to supply the downtown with heat. Never heard of rock storage in the US. I'm interested in a reference.

If so, Americans have forgotten all about it, replaced with a desire to do it all with electric batteries.
