Hydro Differential pressure exchange over unity system.

[see3d]

...
I think your logic is way off track with thinking that the air spring effect is going to keep the system going, or assist in any way.  The precharge real benefit is in recycling of pressure volumes that allows for reduced volume usage at stroke time (in a dual Zed)
I am open for correction if you think different !

Red, you are not understanding my post.  My post was made for those who already understand, but using the same term to mean different things, which does not promote understanding by others.  If you can not see where the different situations come from in my three cases in actual builds, then I can not help you at this time.  I am not trying to be rude, but I need to do more work before it is easier to illustrate all the cases for everyone.

See3D,
Your post makes good sense to me, I am not referring to your post in a corrective sense or where they actually come from in your 3 cases.
I am referring to the zed and the implied association of the spring effect to the zed and the precharge as a means to provide enduring power for a prolonged time.
Sorry if I caused any confusion, that was not intentional

You, Wayne and others who pursue devices such as this, far from being out of the box thinkers, are actually trapped by your own delusions. No amount of wishful thinking will create an OU device if the mechanisms you design don't have the characteristics that will allow that to occur.

Let's imagine the problem at hand was designing an aeroplane. You, as 'out of the box' thinkers have decided to use cheese as the material of choice, and to bolster your thinking have only chosen to consult cheese makers rather than aeronautical experts. Sounds ridiculous I know, but Mr Travis's attempt at OU appears to me to be an equivalent exercise.

For the record I think OU is achievable. To my mind manipulating space time itself will be the only fruitful level of enquiry. At this time I don't have any idea what such a device would look like, but I can tell you with certainty it does not look like anything yet shown by Wayne Travis.

Hi Seamus,
I duly respect your constraint conservative position. No problem, man
It is best that we recognize that WE have come to the end of the road

You can't be serious in asking this question..surely? Isn't it obvious that case two describes no more than hydraulic leverage and the conclusions drawn about the energy balance are completely false.

Sure, the descent in case two could generate ten times the pressure but the volume that could be transferred is ten times less. Net result in energy terms is exactly the same as case one. Not overunity at all.

I agree, how is that much VOLUME transferred the same distance as the input with greater pressure?

Two kids are on a perfectly balanced see-saw. You give one of them -- Zedediah -- an apple. He sinks, but before he's down he tosses the apple to the other kid -- Dezdemona. Now Dez sinks and Zed rises. Since the toss was horizontal it was "work-free". Dez takes a small bite out of the apple and tosses it back to Zed, also work free. Now he sinks and she rises. Zed takes a bite out of the apple and tosses it back to Dez. This goes on for some little while, until the apple is completely eaten and the kids are in balance again, each one weighing about half-an-apple more than they did at the start.
