Hydro Differential pressure exchange over unity system.

[powercat]

Not sure what I will do with the money but I do have plans to build a slightly larger and better built unit, one that is more uniform in clearances.

Will the larger unit be a self-runer ?  I am keen to make one that operates continuously,
but so far there hasn't been enough information to make me feel confident at an attempt.
What are your thoughts on a self-running device ?

Can I be permitted here to add my own thoughts about a self runner? Whilst I think it is possible that a self runner will be built in a home workshop, It is fairly lengthy and involved task. If we look at Wayne`s machine, we can subdivide it into several separate systems.
1. A pair of Zeds. Two is best, because we can recycle the "Exhaust" of one Zed to partly recharge the other, and vice versa.
2. A transmission system to convert the reciprocating output of the Zed into rotary motion. Whilst Wayne uses a hydraulic transmission, I think
for a small demonstration model, we could use a modified crankshaft type set up. Even if we do not wish to drive a generator, I favour a rotating shaft as output, as we can then have a camshaft to control the sequence of events.
3. A feedback system, [mechanical] to feedback some of the output to help in pumping water into the Zed.
4. In Wayne`s case, an alternator supplying energy to the load. If you just want a self runner without output, this is not needed.


A complex challenge, but not insurmountable, especially if people work together.


Just my opinion.

A System Rise Calculator data set and picture are attached.

The first is the basic system rise logic used by the calculator.

The second shows the force results and compares the the original stroke water level from the outside retainer water drop and the water height level after a 3". Note that the pod retainer (Retainer 3) gap water level his risen and the next inside water level (Riser 3) has dropped. More explanation later.

The third shows the 'Adjustment' button that must be pressed after the 'System Rise' or 'Start Out Ret. Water Drop' value is changed. After pressing the values will start rolling like a slot machine. If your machine is slow reduce the System Rise value and it will speed up.

The fourth is the calculator file.


Further explanation of Pod Retainer gap water rise:

To go from Initial Precharge to Stroke, water is added which raises the water in the gap between the pod and the retainer to increase the water head. The gap is ~ 12 (D155 cell) SI. Then the system is allowed to rise under pressure, while water is being added to fill in the 719 SI (C155 cell) area below the pod inside the pod retainer.

During the system rise a dynamic balancing of water/air levels occur. As the system rises the physical air space will increase lowering the pressure and water head and slowing the lift. The input water still coming in at the same rate, now reacts to this by overflowing into the 12 SI pod retainer gap increasing the pressure, water head and increasing the lift. There is no stopping it as the ratio is 61 times (719/12), so the 12 is insignificant.

That is why the water level at riser 3 was forced down from 8.488 to 4.255. This was due to the retainer 3 level rising form 52.226 to 62.726, but reduced by the new air expansion volume.

So it is an important step for physical replicator on initial setup, after bringing the system down from idea to stroke level, is to lower the water level in the pod retainer gap and add air pressure to return the water alignment in the outer layers. This is only a one time event.

Wayne had told me before that for initial system setup after the system was at stroke or initial prechage the water could be lowered and replaced by air pressure to realign the water head. At the time I though this was just being used to have the pod sink away and the layers would be the only part lifting for the 2500 LB. But, it's other purpose is to reduce the chance of the pod retainer gap water going over the pod retainer wall into the next riser gap and the additional air in the pod retainer gap being compressible reduces the chance of blowing outer skirts.

For those that don't have Microsoft Office, you can download a free version from http://download.openoffice.fm/free/?pk=26976
It has a Calc module which is the same as Excel.

Webby thanks for your reply and your pictures, I begin to understand the parts of the ZED. Anyway, if you can, make a video with the procedure of imput and output of the system.

@All,
Sorry, but my latest spreadsheet is not responding under OpenOffice???, when pressing the 'Adjustment' button.

I will try to find a solution, but if anybody else comes up with a solution please post.

Thanks, Larry
