You reminded me about material density (displacement v weight). PVC is quite a bit denser than water, and it is the material of the lower valve, and the skin of the bellows, while the spine of the bellows are made of stainless steel, so that the bellows present just a little bit of resistance to...

I really appreciate all the feedback! I don't know the internal pressures, Chestermiller, as I did not have gauges in use. The bellows have a pretty strong spine that would keep them from being crushed by the hydrostatic force, but would allow them to be compressed through their length, so I...

But isn't the water pressure from below stronger than the atmospheric pressure from above?

The valve is attached to the bottom of the bellows and the bellows extend and contract, so the valve can move. There was water already inside the bellows, both valves were closed and the bellows were in their retracted position. The valve itself is denser than water, so it readily sinks, and...

the top valve (Valve 1) is about 12 inches from the surface, while Valve 2 starts out 20" away and ends up 32" away, falling a total of 12"

Also, the diameter of the bellows is 2.5"

The bellows are very light, but the valve on the bottom weighs about a pound

I multiplied 8,760,000 kWH by 0.3, but now I think I probably did the inverse instead. I'm in a design group, and the challenge is to imagine a non-fossil fuel way of making electricity, and I'm trying to figure out how many power plants of this size can power the US. I found out that in 2019...

Thank you for helping me through this. I get 3,066,000 miles per year.

If a power plant generates at 23MW, how many kWh will be generated in 1 year? And how many miles could you drive Tesla cars, at highway speeds (70mph), in one year? Thanks

Would that work for generation as well? If a generator puts out 1MegaWatt then it would follow that 1MW x 24 hours/day x 365 days/year=8,760 MWh or 8,760,000 kWH? Thank you

What I meant to say is that maybe a gearbox like that could be used, just to slow things down, then connect it to the near 50mw input from buckets. The speed of 30 meters per minute seems large to me, only due to the buckets having to turn around the sprocket, and how much destructive force will...

Right. So that's quite a bit of power, but it just seems like an awfully fast rotation to keep up with mechanically. I'm guessing that I would have to utilize a gearbox like the ones they use for wind turbines. I saw something about a 600 shaft rpm turbine gearbox yielding 8mw, but I'm not sure...
