Hi All,
has anybody done yet an animation, how the prociple works ?

As I did not have much time lately to studay the whole thread I would really like to see the principle
in an 3D animation.

Aynbody out there that can do this and show this in a short movie ?

I guess it would become then also much more clear.,..

Many thanks.

Regards, Stefan.

Hello folks.

Reading up on the later posts, good to see more replications developing.

Congratulations to all who have figured out how the basic principle works, not only as a force advantage but also as an energy advantage. It takes a bit of due diligence and time to grasp.

If you examine the patent closely, and read all that has been presented in the forums, a simple model can be constructed (0ne pod one riser) that can demonstrate the force effect and the gain.
The  pre-charge portion of it, maybe not easily understood at first. But then think of it as “priming the pump”. It is required once and stays there for the remainder of the cycles or up until the system is drained. This initial charge is not used to drive the system, only to initiate the cycle. Elastic -air compression- energy storage, kept in the system.
For one pod one riser, make them neutral buoyancy as a system, fully submerged. Compress (pre-charge) to get to the load force needed, move up, (force on the pod is less than force on the riser, diff areas same pressure)  end of stroke remove the load, let it expand, move down (sink) to the original level.
For a 2 zed system, let the portion of the pre-charge move to the other side, and use portion of the gain to get to full pressure and so on.
The Sequence shown in post 373 is quite helpful

I hope this helps.

Also - in our physical testing - you have to allow the air to expand in the system in order to lower the pressure -
If you have too much air in a gap -(by design) you may not be able to move enough to lower the pressure "enough to sink".

The clearance issue interested me, because the increased clearance always showed more lift in my original force spreadsheet. So I ran test on the 3 and 4 riser water height calculators using clearance of .25, .50, 1, and 5. It showed that as the clearance increased the compression/expansion lowered as would be expected. 

The 4 Riser did not work well showing low lift increase up to 1 and 5 was a disaster, blowing out the Pod water. So 6 would be much worse.

However, the 3 Riser system results were impressive as shown in the attached picture.

Didn't consider the input cost change, but the results are interesting.

For this one pod one riser system that demonstrates the principle, the sequence as shown in 373 requires that the volume of water contained by the device increases. I'm assuming then that this cycle can't explain the effect in a one pod system. Can you give an equivalent diagram for the one riser system that clearly shows the effect?

Ok, I’ll try to break this down to the most basic steps - there are few of them for this model construct-, but it'll make it easier to avoid misunderstandings for all the readers who may also follow this.

But lets agree on a very basic conservation of energy for e.g.  a frictionless piston/cylinder.

If we compress the gas inside and then release, the piston will go back to it’s original position, no net thermal energy exchange with the soundings due to compression decompression for the cycle etc So basically we compress a gas from Volume 1 to Volume 2 with V2<V1 and then let it go back to V1. So for this full cycle V1 to V2 to V1 everything we put in we got out.  Agreed?

Let me know yes or no and I’ll continue.

Good work - and very good to see understanding of the process.

Just a small warning on Gaps - increasing Gaps takes away from the prinicple of operation - it is alluring because of the force gains.
The gap increasing may "putout' more because of the Diameter increase - and that increases your input volume and time of operation.

And be very careful into the expansion volume of large gaps and see if you can handle the expansion and not blow the skirts.
Also - Our engineers' modeling results did not not show much gain from 3-4 layers on up - until they understood the effect the layers and on considering both speed and volume of the reused "head".  The value changes with layers and pressure - the higher pressure results in more of the head transferring in free flow mode - which means less work or more stroke.


@ ALL
Be careful not to nail down comments from a year ago - that was when we were testing the closed looped system - extensive testing - since our Data collection model - our understanding has soared.
Current answers are more accurate and so is the understanding - as it is with hands on research.
You can use our long history here as a map of the progress we have made.

One more thing:

Play with the water levels - you can reduce the input pressure without giving up much lift by having the greater differential in the outer (larger diameters).

Stefan - I have 2D running models - but they include some of the improvements - not yet released.

I have put a call into my Animator.
Thank you all,
Wayne Travis
