Hydro Differential pressure exchange over unity system.

[see3d]

I'm trying to figure out a lowfriction lightweight way to keep risers and stationary walls concentric without adding drag and of course with allowing air and water to pass freely.  I'm envisioning something like a Teflon "star" or "gear" with teeth pointing out and in, like a ring, that can slip over the inner tube and ride between it and the outer tube smoothly with loose clearance, preserving the interwall spacing and keeping everything concentric.

I know how I'd do it if I had my shop set up, but I'm looking for ideas for something cheap or free, easy to make, and adaptable to most any design that people are working with.

You might glue 3 or 4 thin triangle shaped vertical plastic strips to the outside of the riser or inside of the tank outer wall.

Hey See3d

Nice work. Does your simulation show the 'air' as compressible? Like when it is under pressure does it occupy less space, as compared to the water?

Thanks

MaGs

Yes.  I also make the air darker grey the more it is compressed to see it happening.

@Fletcher, you are at a significant disadvantage if you have a slow internet that makes pictures difficult to download.  I show my work and think almost exclusively in pictures.  Were you able to download my whole PDF with pictures?

Yes, I was able to download the pdf [it took some time] - whether I can see pics posted on the forum or not depends on the day & hour sometimes, especially when demand is high - currently my service is throttled right back because my month plan was exceeded some weeks ago - nevertheless I can usually see some of a picture [or none at all] so a descriptive of how formula's are made & conclusions reached in clear terms are appreciated to aid understanding.

My sim baseline level sits at the bottom with zero H0, zero air pressure (atmospheric), and H1,H2 at the same level.  The riser is counterbalanced mechanically as is the piston and water in the pod area.  The system starts out in a "relaxed" state at the bottom with only a 1% of design output load weight sinking it.  It is a very easy state to understand as a starting point for the sim.  Then a design load weight of 1 pound is applied on top of the Riser.  Then an input force is applied to the piston via a 1 pound weight applied to a mechanical lever.  Life does not get much simpler than that for something to sim and physically measure  accurately.  I am really designing it as a science experiment for the purpose of easy accurate measurements.  Making a single ZED free run takes a little more Rube Goldberg mechanical ingenuity.

My purpose in labouring the point [sorry for that] about the system starting in equilibrium has everything to do with "previously understood to be" conservative gravity, the cornerstone of Mr Wayne's claims.

N.B. when a system where gravity is the prime mover is In Equilibrium of forces it is ALSO in its position of LOWEST Potential Energy - it can not get anymore 'relaxed' than that - if it can lower its system CoM even further it is not at equilibrium.

The only way that you can test whether your sim conforms to the real world is to build a model in that same position of lowest PE & check the water levels etc.

Then you can be confident that the system isn't 'loaded' in some way which would need energy to restore it to.

I don't think your sim needs counterbalancing of riser & piston water volume/mass - like I said any movement of the piston which lifts any portion above it will be given back later to achieve reset i.e. zero sum energy wise - however the WD to cause the piston & its load to rise can be quite easily found IINM.

TK .. a suggestion - ball bearings or bb's made of low density plastic in a vertical channel - or castor wheel analogues etc - basically something that allows both surfaces to slide past each other & maintain separation without much friction.

Fletcher,

Thanks for your continued inputs.  I can balance the system by loading pressures and heads or other arrangements of shifting water mass, but that is difficult for the initial setup and can change with temp and barometric readings.  My way to do the balancing externally, make it dead simple to adjust during the setup phase, and it also makes it possible to reduce the height of the ZED for the same output -- if my sim is giving me accurate results.  With more layers, that tradeoff might change.  I will have to wait and see.

It is true that setting it up my way is 1% more potential energy loss than the baseline needs to be and wastes 2% of the total potential work that could have been obtained in theory by overdriving it into the stops.  However it is much easier to have consistent mechanical repeatability by giving up that 2%.  That gives some mechanical tolerance and insensitivity to some variations in barometric pressure and temperature.

If 2% is all the O/U available, then that is not a design I would pursue for practical reasons.  We are looking for something with dramatic O/U to produce a large number of KWH in a parking lot space.  That should not be hard to measure even by eye.

I will try to get an updated version of the PDF out tomorrow, so you can see where I have taken the sim.  I will hold off on new animations until I can do more verifications.  I may do a tin can build first.

BTW, I did try a physics simulator program.  It was not a very good one.  Really more like a science educational toy, but it was free and easy to use.  It included mass, acceleration, water turbulence, cavitation, etc. However, it lacked the ability to have the dimensional precision I needed, and the Piston leaked water drops, and the Riser did not self center... LOL  That was the point when I decided to write my own to eliminate all the unwanted side effects.

Hello Webby,
My team is currently planning the build for our desk top self running water pump.
I would love to see your teams creativity with the ZED technology!
How about a new challenge for you and your team..a $5K ZED  challenge.
Specifically designed by your team to ease measurements of input and output.
Two single five or six layer systems will do, or a combined system.
It does not need to be transparent.
Weight of the riser is not an issue works as a counterbalance - steel, aluminum may be used.
The risers may all be attached to one lid.
The system needs to be able to be measured and have access to each layer (tubing both air and water).

Part two: $10K ZED challenge ----5 layer, dual Z.E.D. water pump.
If your design team connects the system together for a self runner - I will double the 5K Challenge to 10K.
and each member of your team will receive a HER ownership certificate - valued at the current valuation and equal to the prize.

Five members max - pick them wisely.

Suggestions:
You do not have to beat our team - but time is important.
plan on 1/4 or 1/2 inch gaps between risers and ring walls - will work fine.
If you start with a pumping system and then size accordingly - a lot of time is saved.
The previous expectations apply - after a reasonable time of testing and reporting - you must send me the units, you are welcome to make an authorized extra set to keep for yourself.
Placard with your team members name and the name of the device Zydro Energy Device on all systems made.

What do you think? Up to it?

Hi Mr Wayne,

Okay,  love game time. I am not a member of Mr Webby's team, but have a question as I am a friend of  Mr. Webby, will your team have access to your new improvements or will this be based on the current demo model specifications that we both understand? Just want to make sure we are on the same playing field.

Thanks, Larry
