I appreciate the apparent ease of controlling such a large amount of potential energy to spin the turbine/generator. Getting all this power sychronized to the power grid takes a gentle touch !

Once had a young engineer working at a very small dam close penstock inlet valve way to fast. This caused several hundred feet of pipe to implode.

@@adamruck no the air inlet was to small so the water rush down the pipe into river. This moving water with a small air inlet created a vacuum. The vacuum caused the old and rusted penstock to implode. I tried to find the news article but it was a small town in NY. All I remember it’s next to shoe factory. I was commercial diver at the time and worked on a ton of dams.
