Gravity Mill - any comments to this idea?

stefan,

i think when you get your internet back, you need to read my post and go back to http://www.icestuff.com/energy/elsa/ and re-read all pages, not just glance at them.  try to get a handle on what John Herring is trying to pass along.

i don't think we need to go down that problem riddled road he already has.  if we don't take advantage of his 30 year effort, shame on us!

i'll be back when you catch up.  if anyone has questions about Mr. Herring's designs, i'll try to help out.

Now the pipe above seawaterlevel is still empty. Now lets fill it up with 1 meter high water and again lets calculate how much air we need, so the shuttle is not moving...
Now we must rise the volume of air to double the amount, so 1570,8 Liters at 2 bar, so the shuttle is not yet moving.
Also due to the hydrostatic paradoxon it does not matter, if we have a very small tube or a bigger one above sealevel, as only the height of 1 Meter water height counts. Agreed ?

Hi TBird, did you come up yet with a conclusive calculation yet ? The problem I see isin the calculation of the energy required to switch the shuttle into 2 different volume states. We have to calculate that via the air pressure as this also hinders any mechanical movement, if you want to do it with a mechanical see-saw torque-arm press. In this case you also have to overcome the different airpressure values, so itis just easier to do it just via pumping airpressure and where I have worked out now all the formulas !

Okay now back to the calculation. If we now fill in instead of 1570,8 Liters e.g. 1600 Liters at 2 bar, the shuttle will rise and also push the water out higher than 1 meter, cause we made the pipe smaller above sealevel. As the suttle moves up, the airvolume will also expand inside the shuttle and thus move the shuttle even faster to the top, as the waterpressure is reduced, which will make the airvolume bigger.( I still calculate it here for the balloon shuttle which can expand with attached weight) Agreed so far ?

Interesting ... found this on the web.  http://www.glassbuy.com.cn/en/offer/printshowinfo.php?Id=14937

Looks like John was looking for glass tubing back in 2005.  Also has a contact phone #.
