It doesn't work if there is any wind at all. Even with a dome over, it could store only a pitifully minuscule amount of energy. There are lots of YT vids about how stupid it is. Compare to e.g. https://news.ycombinator.com/item?id=31736539 https://news.ycombinator.com/item?id=31736539 . Somehow people are unable to do even the most trivial reasoning about cost, where energy storage is involved: expensive stuff is expensive. Utilities will buy what is cheap to build, cheap to use, cheap to maintain, and reliable. NRGV checks zero boxes. (Hydrogen and ammonia synthesis equipment will not be super-cheap, but its output burns in gas peaker turbines, and can be sold for hard cash.) Even NRGV dropped the crane thing like a hot potato the moment they got their IPO cash.
