Gravity Mill - any comments to this idea?

[FreeEnergy]

the water that the shuttle pushs up and saves to a container is the energy needed to lift the weith to the shuttle so it will sink.

Here's an idea I have been thinking about for a few days now and cannot see why it cannot work, I am not even sure where the additional energy comes from:

You have a cylinder 1m diameter, 2m high with a piston weighing 10,000Kg.
The cylinder weighs 1000Kg.
They are connected to a pulley and counterweight of 10,500Kg.

With the top of the piston sitting level with the water surface the piston is 2m below the surface.

The piston is allowed to sink onto the piston expelling air via a tube at the surface.
The whole assembly is allowed to sink to 9m (bottom of cylinder).
Then the piston is released and the weight pulls in air from the surface and overcomes the pressure at 10m depth by its own weight.
The whole assembly is now bouyant and can travel back to the surface with the force of 2,000Kg - difference in counterweight = 1500Kg.
When the piston and weight reaches the surface it can start the process over again.

I have racked my brains, but I cannot see where the flaw in this is.
Maybe I missed something.
The only big loss that can occur is if you have to move the very heavy piston upwards using force, but I have avoided this and still managed to get air in and out of the piston at the required points.
There are various locks required to hold parts in place during the piston move stages.

If I cannot find out where the flaw lays then I may end up building a small model to prove the idea.

Kingrs,

Sorry, but I am having a hard time picturing what you are describing. Perhaps you could post some type of drawing showing what you have in mind. A little detail on what you mean by a counterweight/pulley system.

We appreciate your input.

Hi Resinrat,
As with everything, you start to draw it and then suddenly it hits you.
I got to step 4 and realized that it cannot work.
At step 4 you need to release the main piston weight which is energy you have lost and cannot get back during the ascent back to the surface. So what will happen is the cable for the counter weight will need to get longer each time. Shame, I thought it was too good to be true, that rules out any gravity mill I think.

kingrs,

Thanks for going through the trouble of drawing it up anyway, even though it is a failure.

One thing I learned in Research: all failures need to be recorded and analyzed WHY they failed. That way we all know what NOT to do.
