Gravity Mill - any comments to this idea?

when the shuttle goes up, the valve closes, and when it comes down, it opens.

it's not opening for air passege but for water. when the one-way-valve-shuttle goes down the pipe it opens for water to come in, then it closes when it goes up to push the water to the upper half of the pipe.

Hi stefan.

Thanks for the good calculation - very good and exact job.
There is one thing that makes the whole thing running: You calculated the energy gain and loss while the swimmer is 2 meters under the water, so it has to go 2 meters upward and pump 1m water in a reservoir. Then your calculations are right then energy gained=energy lost when compressing. I think, never mind how deep the swimmer is and how much water he has to push up, the needed energy is always the same, its always the energy we need for pumping 1m water in the reservoir, the 1m above sealevel. As long as sealevel is not reached by the shuttle, it has the same buoyancy which needs to be greater than the force of 1m water above the sealevel. Correct me if I'm wrong or simply tell your criticism!

I think, the problem is - the deeper the shuttle goes, the more pressure we need to reinflate it...

no air being pumped in my idea

Well I am now convinced that it does not work.

It is the same analogy, as if you would take a U shaped tube,
fill it with water , so that the water is 10 cm high in each leg of the tube.
Then use a syringe in the right leg to press air into the upper right leg above
the water. You need Force x distance energy to press on the syringe
piston. Then the water in the left leg will go up, but it will only
have the same height difference as much energy  you added via Force x distance
via the syringe.
The height difference can be calculated via:
Left water leg Potential-Energy = Syringe-Energy
watermass x g x heightdifference = Force x distance.

So there is no overunity to gain in here.
If you see the watermolecules  as small balls it is clear, that
you don?t gain any energy out of lifting a few balls up, but you have
to pay the same energy prize for doing this by pumping the same energy
air amout unter water !
So if you can find an error in my ramblings, please let me know.
Thanks !

Hi TBird,
let me know, where my errors should be.
Thanks.
