I actually bought stock in them a few years ago. I note with disappointment that I have not become rich. But they aren't out of biz yet, either :-)

I thought they would be a good fit for home solar installations, as an alternative to chemical batteries. The fact that they go in the ground is a plus. No wasted space for big battery banks, and low maintenance.

At least one of their models would actually be a good size for a home installation. It stores a few kilowatt-hours of electricity. But I don't think the current price is conducive for a residential buyer.
