Congrats on the progress Dennis. We're all looking forward to your next release.

Thanks for the huge effort and we appreciate the updates!

The important part of the original graph as stated:   More important is the greater slope of the Travis to the Hydraulic. Travis doubles the output difference from Sunk precharge to Final precharge.

Hi Larry,
With regards to understanding the graph data in your post #2485, I saw an odd trend that brought me to the following questions ( To put you at ease, I post with peace, I do not have any intentions to do a jugular vampire act on you, you must be weary to have received some blood stained pages lately)

1.. The total PSI is very low (as read from the Y axis).  Is the listed pressure, the overall PSI or only for one layer?
2.. The non-linear travis force/psi trend is negative going slope, (I would have expected a positive slope,  increasing lb/psi as pressure increases)

Are you 100% sure ?

In our system the head travels up with the stroke,  this results in a special condition at the end of stroke,  namely - all the energy you put into the system is still there. The load was up and is removed but the buoyancy "head" is still intact.

You limited the stroke - unlike other buoyancy systems we do not fill,  float and then DRAIN and then sink. As you have discovered, removing the head creates a sink condition. The sink condition is directly related to the static load.

Now we move the head - into the other Zed (equalization - free flow as we call it). At first, the zed does not sink during equalization it sinks during stroke of the other Zed.

Now in the equalized position, we use the pressure in the lowering Zed to supplement the Stroking Zed.  Guess what this does for efficiency..........very exciting

The weight to the riser split the desired force, like this with our 6000 pound force model,  2000 pounds of weight lifted is returned in the system (in the exhaust of the lowering Zed),  This 2000 to fuel the internal operations and this 2000 pounds absolutely free.

In short, our three layer system has a total of 1/3 the Ideal, absolutely free.

Do not get trapped into thinking you have to exceed the Ideal of a system to achieve OU - that would be magic - our system is simple physics - seen in a new light.
When you wrap this together - you will see why

Now you know what I saw in the hot tub back in 2008 in the Travis Effect, and why we dropped everything and pursued this against all odds.

I am stuck at the air port - nine hour wait.

The water in the pod section is always under pressure - the pressure is related to the direction of travel and stage of the process.

When Zed 1 is all the way up - it has the full charge in Head + the volume inside the pod added for stroke length- It is at the top because it has just finished its production stroke -

At this moment the Hydraulic assist is "on" but no movement or consumption of energy. - To be clear - the hydraulic assist is what adds to the head pressure from the lowering Zed in order to overcome the hydraulic resistance in the production cylinder - or the load.
Both Zeds are connected to opposite sides of one a piston (bags in our last model) that piston is at the end of its travel or near empty at zed one.

Zed one :  has the highest presssure (8 psi - example given last week)
Its at the top of stroke - high pressure connected to Mass exchanger --(bags - cylinder)

The other Zed (Zed Two) is at the bottom of the stroke It still has 4.6 psi (caused by the weight)

Now the first step is to let go of the hydraulic assist - The two Zed's equalize head pressure - so both heads are now at 6.7 psi --both zeds are still in the same position they were in - but the Mass exchanger has traveled half of its distance.

Zed two is ready to be pre-charged - this means going from 6.7 psi to 8.0 psi (over coming resistance pressure).

The precharge is nearly instantanious - when the first hydraulic assist is turned on - when the pressure drops to 4.6 psi - about 3/4 of the total travel - we kick on the second hydraulic assist cylinder.

And we finish the stroke (we are capturing the buoyancy during the Stroke.
Then we are half way through a cycle - Zed two is up (8psi) and Zed one is down (4.6 psi)  ready for free flow to begin - the other direction.

Let me be clear - we exchange 1/2 of the hydro transfer during free flow - no input - then we pay for 1/3 of the next quarter, and then less than half of the last 1/4 .

That is our total input - nothing else - very simple.

The layering system makes the "Exhaust or water transfer" pay for nearly 70% of the total input cost for each Zeds production stroke (roughly - three layers - better with more layers).

When our third part engineers measured the up stroke - they were excited - but when they realized that all the energy for the up stroke was available for the transfer - (minus standard losses)

The Riserweight in the system reduces the ideal of the unit - but do not mistake ideal for efficiency, yet the riserweight makes the transfer more powerful and the size of the riserweight (percentage of ideal) is based on the number of layers.

So when you see the three layer system has about 1/3 of its ideal lifting weight, you know the reason.

A point many critics make is to ignore that stored energy in the head is still complete and intact at the end of every a stroke and can be exhausted at a steady minimum pressure that results in more return than the weight due to the travis effect.

The outer layer has a significant purpose at this stage of understanding the system -
The Last riser - the largest surface area - needs very little head to overcome the total weight of the risers - keeping that in mind, The Pod is "also" used to keep the weight of the system neutral.
The weight keeps the system in a precharge condition.
Now - in set up - you want the maximum usage of the pod, a fully submerged pod at stroke is best. So sink the system , you only want to lower the water (head) around the pod enough to sink. So if you will add ten inches of head to the pod in order to stroke - reverse that ten inches to sink.
Now the last riser is you adjustment - you can add or subtract the head (water volume in this case) in this layer to balance the system.

Just an example.
If you use 2500 pounds of weight to keep the free flow pressure at least 5.0 psi, the pod itself will not neutralize the weight - just increase the head in the last layer - a tiny bit of pressure goes a long way when you have a large surface.
In our set up procedure - we over charge every layer - then lower the pod water level to the lowest operating point - then lower the water level in the last layer -until the system begins to sink, - or 5.0 psi is reached.
Set up is complete and matched to the weighted system.

Hi Seamus,
Your reply post is a dead give away into your mind.
I agree with you that the Travis effect is worth to allocate some time for.
