In those places with deep* and wet mines They wanted to bring back the entire Trompe system, but could never get their plans past the bean counters
who objected to the lengthy R.O.I.
At the time the Engineers were talking about nearly free low pressure compressed air- (Still the leader in all forms of drilling/mining by many factors) and
simply upgrading the technology from early 30s to late 50s.
Short version: For a long time- maybe forever, this will be a niche market, however- anywhere you already have falling water that can be contained for nearly
free low pressure Compressed air and any other source of interruptible power service Then I think this will have a future
