@Cisco.Sorry that should have been Reply 523 on page 35.
@Seamus101. I can see what you are getting at, but to be honest, calculus is beyond me. I am sure that there are members here who are far better qualified to comment.

@TK re: Cartesian Diver.  That was a cool video!  I'd never thought to use the effect to amaze my kid.  This should be a hoot!

Thanks again,

if only this were so, but it is absolutely not true. Injecting any water would begin to increase the head thus it would become more and more difficult to push the water in as the resistance rises. The forces increases but the distance over which those forces can act are decreased. One needs to integrate the force and displacement over the stroke (basic calulus). When you do that you'll find the energy remains constant, (minus any losses due to heat but we needn't complicate it with that.

Hi Seamus,

Please note in the example drawing in reply 537. The head is the same in PRECHARGE and after the water is FORCED IN.

@telecom. I have yet to study the variable geometry piston. There are still parts of the actual cycle that I am struggling to grasp. I suggest you read reply 525 on page 35, as this is one of the best aids to understanding , as it takes us step by step from the basic Travis Effect to the working of a ZED. Having understood this, then the original sequence of diagrams by mrwayne will start to make more sense.
      The most telling thing about this device is that the resistance to the water injected is only the head of water it has to resist. And when that water is sucked out again as the load falls, it still has half of its energy recoverable. Mathematically, it seems to stack up perfectly. No one can say specifically where the excess energy is coming from . At this stage , that seems to me unimportant.
       To sum up, I have spent ages studying this, and for me there is no Eureka moment , just continuing small steps in understanding .

Sorry to say this, but variable geometry piston is not going to work out - all the O/U is being spent into retracting piston2 into the piston1 at the top, plus some.
As the last resort, will study  post 523.
Generally speaking, it is close to impossible to get O/U in a closed system - it has to be open.
Examples of the open system: wind, waterfall, sunlight, gravity, electrostatics, magnetism.

@Telecom. As far as I can see the maths seem to stack up in favour of this system. We have some pretty good anecdotal evidence, and the opinion of Mark Dansie. Until and unless someone replicates this, then we are not going to know anything for certain. Simple at first glance, as ever the devil is in the detail. We have been told that we need close gaps between risers and the walls containing the rings of water , so one of the main problems is we need custom made cylinders .
        I was interested to see that you include gravity in your list of open systems. As someone said earlier, buoyancy is just gravity misspelt.
