Gravity Mill - any comments to this idea?

I could see using a the water collected above to drive a variation on leverage to get enough pressure to press on the piston

That's the plan.

The whole thing is significantly simpler, in engineering terms, than ELSA.

Just noticed that this new design reduces the quantity of water pumped on each cycle.  So it won't work.  Oh well, back to the drawing board.

Hi Pranja,
yes, we should use the massive volume the ELSA was able to
lift above the shuttle, but just use it in a different way, like
pumping it still under water into a pipe, where it turns a generator
or would wind up a spring or something else, so one could later recompress
the ELSA shuttle.
As long as you keep the water below the sealevel, it still has great
potential to lift really a lot of water above the shuttle...
So this must just be used differently I guess.

Let?s see, if you turn a gear via a pump at sealevel and
gear it up, so you can lift an external weight, how much
weight can be lifted how high ?

Stefan,

Now that sounds like great "out of the box" type thinking. Whoever said the water had to be pumped above sea-level? The moving water needs to be harnessed for energy. Enough to compress the shuttle, or a variation of compression in Prajna's cartesian diver type design. The compression mechanism would need to be above sea level but not necessarily the energy collecting one.

Prajna's idea of the magnetic piston, cartesian-diver shuttle may still have potential. It does simplify the shuttle design.

here is an idea !

We never have used hydrogens lightweight and hardcompresibility properties.

I suggest shuttle that is when went is opened fills up with water and goes down to bottom of
device.
At the bottom of device (or some natural area... sea,lake) there is effifcient (only 80%) electrolyzer who will fill the shuttle
with lightweight H2O2 gass. Shuttle than climbes up and when reaches top point of device we take H2O2.

So energy should be extracted from

heavy shuttle going down (metal shuttle filled with watter),
light shuttle (filled with H2O2) going up,
and H2O2 extraction from shuttle when it reaches the top.
