Please point to the specific post where you laid out the official analysis of a ZED, including the part where the free energy supposedly comes from.
Sure, can't believe you keep missing this....
Conditions At least three layers Each ZED:
ZED A Sunk remaining head due to riser weight and any added weight - ZED A will be the receiving ZED,
ZED B is at the end of delivering a load and in the raised position - and was not allowed to Bob up after the load was removed.
.................
State one - Start with sunk - still head remaining - equal to the weight of the risers - and any additional load. (additional load is sometimes used to reduce time by reducing expansion and contraction during cycles)
p.s. Adding weight is counter intuitive - most people assume adding weight induces losses
Lesson to be learned - trying to achieve Ideal usage results in self determined conservative process.
The next state is post free flow - this is where the other ZED A and B have equalized between the stroked ZED and the sunk ZED. No riser movement in either ZED - only fluid and pressure.
Note: Free flow results in equalized pressure - but not equalized volume.
The next State is changing from Free flow too "precharge"
Full precharge is the end of the state between free flow and enough buoyancy to nuetralize the determined load and no riser movement either ZED.
The process to get to the full precharge state - two inputs are utilized :
One - the continued consumption of pressure from the ZED B - and the hydro assist.
The hydro assist adds enough pressure - that when combined with the exhuast from the other ZED - reaches load neutrality (buoyancy). This is full precharge for ZED A.
Note: ZED B will not sink until the stored head has dropped below nuetrality of the risers and any added weight.
The Hydro Assist continues to be combined with the Pressure from ZED B - the input cost is the differance between the sinking ZED pressure and the stroking pressure required.
The next state is the Production Stroke of ZED A. ZED A stroking and ZED B sunk is the first half of a Dual ZED cycle - the process repeats in the other direction - notice I did not say reverses.
.................
To understand Stroke - you must determine both the proper load and the proper stroke.
The proper load is the lift safely available at the determined end of stroke.
Iterations are helpful..... I will give you a rule of thumb - Do not make the stroke longer than 1/11 the height of the ZED.
(another counter intuitive - short stroke is a more efficient process)
Use your baseline calculator already prepared to determine what the load is at that height - and that is a good load - presuming riser weight and any added weight has already been considered.
.........................
Unlike the states Mark described - the precharge and stroke is only released into the other ZED - not bobbed up or consumed as production.
The transfer of the precharge and Stroke is made mechanically more efficient as Webby described and posted two of our methods.
but you do not need to add those improvements to find the outcome.
.......................
Last notes - when the full precharge is reached - any additional volume input into the ZED A results in production - so once precharge is hit - no consumption of the previous pressure occurs - the ZED B hits bottom at the end of the production stroke on ZED A.
In simple observation - the true cost of a stroke half cycle is all of the Hydro assist - which is also the stroking Pv ZED A, minus the sinking ZED B Pv, and then repeat for a full cycle.
The production cycle is both ZEDS having produced once and combined.
A full cycle is a return of ZED A to "Sunk.
MarkE - if you do understand these States - you should be able to see how we transfer two sets of PV left and right - not consuming that value and truely reducing the total input cost - the remaining input cost is the hydro assist.
Lastly - the Hydro Assist can be a external input - or powered by the Production leaving excess. When you determine the cost of the Hydro Assist versus the production - you will understand why I have been so patient.
The Excess or Net per half cycle is no more than the value between the Pv sinking and the production - Not magical - but free.
And if you can't understand - Larry makes a pretty decent spread sheet. that covers the whole process.
Hope that helps.
