Hello!
Okay, a little bit of backstory. My uncle was arguing that you could siphon water from one part of the sea to another part to generate electricity if they fell on turbines on the other end. He used a siphoning example , as in siphoning gas from a car on anything else really, on how it would work. He also mentioned that because of earth curvature that it would have about a 10m fall.
I immediately saw some faulty things but don’t really have the background to be so sure about it. What I mostly opposed was the fact that it wouldn’t be a fall if the pipe followed the earths curvature . The sea to pipe height would be the same at both ends and therefore not work because there is no fall in height. Even though one end would be 10m lower but that’s only relative to each other not an actual different height.
So who is actually right here?

This would only work if you ran the pipe past a thermal vent like a caldera. With a one way valve, water would enter, leave as steam, travel uphill a short distance and then condense back to water able to be used in a gravity turbine. Not exactly siphoning. The main problem I see is if it is scalable enough to be useful. Scaling of another type would also be an issue.
