Gravity Mill - any comments to this idea?

Stefan,

Just a thought. Once the main tube begins to rotate, the shuttle may begin its ascent once it goes past 90 degrees of rotation. Maybe some type of lock may be needed to hold the shuttle in place until it reaches a full 180 degrees of rotation, otherwise valuable energy is lost.

This is getting more complicated. I like simple, but then again, I am simple minded.

Nice inovative idea though.

Ok guys, I couldn't sleep so I have designed a simple system for recompressing the shuttle and releasing the air when it reaches the bottom of the pumping tube.  It assumes that you use some of that lovely excess energy you have stored to run a compressor that will supply compressed air to the shuttle.  Now it is just a matter of designing what will happen above water level.

It's on my website http://declarepeace.org.uk/energy/elsa.htm.  Enjoy.

Hi prajna, the idea would work if we are able to completely seal up the shuttle from the pipe sides. Do you think, that can be made that easy?

stefan, I also thinked about your idea this night. We could also do it that way (see image).
Perhaps we can use the compressed shuttle as it is, without the need of recompression, and simple rotate the whole apparatus INSIDE a water basin.
I'm going to make some calculations about it.

Mr Herring replied again. He says that currently he is not able to join our forum or submit images because of his old computer. In 6 weeks he is going to buy a new one. He attached an image with some personal informations, its the same as we know from http://www.theverylastpageoftheinternet.com/forsale/plans/elsa/elsa700.htm.

I again invited him to join us here - lets see what happens.

Yes Andi, this way it could also be done, but then you need a much bigger main watercase, but if you have a garden with a pool that will be okay, so the main tube could rotate in it.
