Hydro Differential pressure exchange over unity system.

and place the 4" can inside it . Now we have 3 more cans , with diameters 5.5 , 4.5 , and 3.5 inches diameter
  Participation without a full understanding is futile.


  Momma always told me that two Zeds are better than one !

Two Quick points - tight clearances - Head pressure is head pressure - unless you get to the caplilary effect. SO make it close as you can - and still have a gap.
This will reduce the volume that it takes to activate the Travis Effect - smaller gap - more effecient.

oops,

The same thing goes for the thickness of the walls - Small/thin - do worry about the pressure - the effective pressure will only be the total hieght of one layer. so if the layers/cantainer can hold up to the water pressure of it sitting up right full of water (without contortion)- they will hold the pressure in system.

@neptune,

I believe you have most of the fundamentals covered with your description of the build in your previous post.  Here are the differences and/or next considerations that I have:

1)  The walls of the first set of cans may need to become slightly lower from outside to inside.  I believe the outermost must be considerably higher than the two inner ones since it houses the water head that is exchanged between the two Zeds and also defines the stroke of the system.

2)  The three cans that become the buoyant members (pod and risers) are all attached?  That is different than the patent.  It may be how the unit operates, but I think it would make assembly a problem.  The inner and outer riser need to be installed while allowing for the air inside to be pushed out through a vent in the top.  Then the vents are sealed.  So they need to be installed one at a time and not as a group of all three.

3)  The outer riser needs to have an outer wall that extends up beyond the bottom of the "can".  This is again because this defines the stroke of the system.  Water must not cover the top of this riser, or we end up with that much more water that needs to be transferred between Zeds.

4)  The inner most can needs to be made into a "pod."  So an empty, sealed can, with a top and bottom.  This is different than the patent since the patent diagrams show a system that exchanges air and we (I assume) are building one that exchanges water.  Mr. Wayne has said that this change from air to water exchange allows for a pod of this new configuration that is not in the patent diagrams.  Hopefully he will correct my understanding if it is not 100% correct.

5) Finally we need a way to "pre-charge" the system.  A way of introducing (pressurized) air from under the "pod" section slowly.  It will eventually fill all the "rings" where air is need and balance the water pressure to initialize the system.  The risers must be held down when the air is introduced.  The pre-charge is complete when bubbles are seen rising in the outermost ring of water.  Then the air inlet is sealed and never used again (unless the system needs to be relieved of any potential energy prior to maintenance, etc.).

Am I missing anything?

Hope this helps.

Many thanks to mrwayne and mondrasek for the time you spent helping me. My understanding is progressing by leaps and bounds . A way to introduce air under pressure , and prevent it escaping . For a model, that could be a bicycle tyre pump and valve.

@Mondrasek. I would be very grateful if you would comment on my last post. Am I right on the arrangement of cylinders? What about my question on the "shape" of a volume of air .


I would think it unlikely [but not impossible] that there will be a team build on this device, due to members being widely scattered . Individual builds are much more likely .


When I FULLY understand this, I will most likely have a go myself. I am sure this applies to many members.
A patent, being a legal document, is not the best teaching aid.

I am headed out -

but wanted to comment:
Shape of the air is not the essential - except in consideration of stroke - then a straight wall matters - they keep the clearances during travel.
For your predictive measurement - pretend that all the layers are stacked on top - not over eachother - sealed and submerged (full of air) that is your Maximum lift your system will have.
Second - collaboration is good - it will take as much effort to build the transfer system as it will the layering system, and then you need brainstorm how you will show the work?

Each can be a seperate job. (just like the real manufacturing process is working out).
The key is to make a decision on the size -
Diameter of the inner chamber will dictate volume needed - keep you stroke lenght short - no more than one inch - (trust me) - will explain later.
So now you can have your volume -
If you find the rubber pump or something without to much static resistance first, you can size the inner  tank to it.
