Hydro Differential pressure exchange over unity system.

[LarryC]

The pictures show the 4 layer, and 3 layer system at Stroke PSI. The 4 layer has a higher PSI, but has the same safe outer skirt level as the 3 layer. Some important fields are the 'Water Head Change % over Pod water Level Change' and the Total Force field. This shows that the 4 Layer requires less Pod retainer input water then the 3 layer, while producting more lift force.

A 1 inch difference change in the Pod level can be shown by changing the 'Out Ret. Water Drop' by entering 4.5697 in the 4 Layer and 4.6887 in the 3 Layer from the original 4.38. The Pod force will change by 26 for each 1 inch difference, because it is linear. The Layers force will change 83 for the 4 layer and 75 for the 3 layer or 10.7% increase for the 4 layer at this PSI.

The attached spreadsheets xls files have updates to show the lifting force.

@LarryC,

Wow!  Nice find.  I mean, I could pretty much see that the added layer would increase the output force.  But at a reduced water volume change?  That I didn't imagine.  But maybe this is why the numbers that Wayne is stating for the scaling of the system with layers is not linear and increases at a faster rate with added layers.

Keep it up!

Hello Larry,

My engineers worked the layering system originally from the outside in - this will become problematic later - they had to start over.
Eventually your do not have room for you Pod and gaps.

It is better to start with the pod of choice and work your way out.

The main reason the efficiency increases so quickly is that the output power increases faster then the input costs.

Adding layers is increasing the total Surface area - "Diameter" - without increasing the input volume.

Things are going very well here - and your work is great.

Hi Wayne,

Thanks, but there seems to be some confusion as to what my water height calculator is doing.

'It is better to start with the pod of choice and work your way out.'  That is what it is doing. Please see the 'Channel SI Calculator' section at the bottom of the spreadsheet. It starts with the pod diameter and uses the entered 'Thickness' and 'Clearance' to build outward. These values are used thruout the calculations to ensure the channel volume's are correct.

'Eventually your do not have room for you Pod and gaps.' Cannot happen.

The main difference between my method and others is the water height calculation logic.

There is two ways to do this, increase the pod water height or decrease the water height in the outer layer, which can be backed into a increase in the pod water height.

If you choose to increase the water height in the pod, the calculations would take many recursive iterations to do it correctly, because as you change values in one layer all values forward and backward need to be recalculated over and over until it settles, or you could just do approximations which is not as accurate. I could have done this correctly with a excel VBA, but it would have been very confusing to most and that is not my goal.

By choosing to decrease the water height in the outer layer, it simplifies the calculations as it does not require recursive iterations and is more accurate than the approximation technique. The decrease in the water level of the first outer layer forces the adjacent column water level to increase. Due to a decrease in water head this causes the air in the next column to expand and forces the next water level down and so forth and so on until the pod water is forced down. Another words, it forces all inward columns to align. You have seen seen that effect with with the previous 5 PSI example, is it correct or not?

Just Confusion on my part,
When I read about the "Volume reduction" on the input - I though the pod area was shrinking -
SO I presumed you were trying to fit the four layers into the same space as three.
My mistake - well done.
