Has An Important Property Of Fluids Been Overlooked ?

Hi,
    mrwayne put me into a thinking mood. Everything, save a bit of heat in the Earth's core has been driven by the Sun. Everything
in the future will be too!
  Even if we come up with fusion, it's the Sun that will have given us the original energy to do the task. There's abundant energy
coming to us, we must learn how to use it.

I am quite disappointed in the lack of inquiry of this thread.  Fletcher is one of the brightest minds on these forums.  I would have expected others on the same level to at least try to understand what he was trying to convey and see where the discussion would lead.  Fletcher has offered input on many a thread.  Let's return the favor.

Hi,
   I think that Seamus103 has been trying to tell us something. His offer of $50,000 dollars within a year for a result.
Liquids just don't like being stopped when flowing, because of inertia, coupled with the fact that gravity is very weak.
If a way of harvesting gravity could be found, using a liquid, a device would have to be hundreds of tons and the speed of
each cycle would be severely limited due to resistance.
  Now it's up to one of you to show me where I'm going wrong,
                                                                                              John.

Yes They Have been overlooked.  Hydraulics, double acting hydraulic pistons, transfer force.  What if a portion of that force came from the downward force of gravity, and no by the way you did not provide that energy, you do not provide that downward force of gravity.  Just a thought...http://www.youtube.com/watch?v=h7id0SCgRzk&list=PLFE742D3CA92894B4&index=1&feature=plcp

Who said anything about a membrane?  Gonna take a better comment than that to discredit this.  I was agreeing with fletcher with this design I came up with couple days ago, I am sure that I am not the first. 

It would not rotate fast at all, so no...centripetal forces would be a problem because it would be rotating to fast, if centrifugal force kicks in to strongly, it would counter act the basis of operation.  I believe that by using the Hydraulic system, the basis of hydraulic systems to transfer force, only moving the attached weights.  I would assume that the attached weights would be the driving factor and force multiplier.  In this I envision it to turn by breaking the so called "Law of the lever" because you are constantly shifting the rotating elements center of mass, balance, gravity etc.. I believe that a slow moving wind turbine generator would be the best choice, and then you can load it up with weighs increasing the rotational torque.  If the piston only lifted each weight only 12 inches, that means it would swing down and travel a total distance of 18.84 inches.  In this I kept it simple,  When the weight reaches the top most position of rotation it is moved outward and then when the piston reaches the bottom most position the weight moves inward.
