Hi!!... No-one else has answered, so I'll mention something of a similar engineering, but in
REVERSE !! haha...
Instead of using the
vertical oscillation of water to 'produce' energy, I'm reminded of a 'pump' that works in reverse!!

It was called a "
Humphrey Pump" from back in the 1950's or something. (
Very large). It was 'something' like a 2(4??) stroke engine,
where the oscillating 'water' was the actual '
Piston', and the explosion of gasses above, drove the 'water' (piston) down, to cycle the
water flow! In a little remote town in
South-Australia, called "
Cobdogla", there is a working museum with the last known working unit
in the Southern Hemisphere!. I've watched it working, many decades ago, and the 'gas' it burnt/exploded was produced by burning coal.

Just thought I would mention it... 99.99% of people would never have seen/heard of it!!
