Hydro Differential pressure exchange over unity system.

First can I say a big thank you to mrwayne for dropping by. Although I am gobsmacked by the intellect and intuition of some of the members here, we are going to need all the help we can get. And who better to help us than the Main Man.
   I had a little idea when I was out riding my electric bike today. As I was passing a farm, I was looking at a large tank used to store diesel fuel for tractors. On the side of this tank was a home made device used to check the fuel level in the tank. It consisted of an adapter fitted into the tank wall near the bottom. From this, a clear plastic pipe extended up to the tank top. where it was open to atmosphered. So the level of fuel in the tank was the same as the level of fuel in the pipe.
    Suppose we built a ZED from non-transparent materials . We could use this idea to "see" the water level in each compartment, but the upper end of the pipe would have to return to the compartment through the top. This would be possible if all risers were fixed together at the top, as I believe they all rise and fall together anyway. Any comments ?

Thank you.
Exactly as we did our first six models - long clear tubes - steel tanks. very simple only draw back - you can not be sure what the water level is - just the combined air pressure and head - why we eventually went to the effort to install sensors for both.

The water head at any pod or riser is only due to the difference of the height of the water on the outside vs. the inside of that member.  That is the only head that acts on each individual member.  I believe the calculator spread sheet is missing a "Next layer" line under Riser 4 where a good portion of that "large force" needs to be subtracted.  The majority of the total lift is actually coming from the Pod and Outermost Riser?

I think the way this spread sheet is laid out might be confusing.  The buoyancy of each member is the Surface Area x Head on that member only.  So the biggest member (Outermost Riser) always has the largest Surface Area and possibility of the largest head.  Each inner member has less Surface Area and less possible head.  So the possible force coming from each member must be:

Hi M,
The pod calculation that was done, used the volume technique (2548), so let's use the Pressure Difference technique which is also valid.
                      PSI      DIA SI    PRESSURE
Pod top         10.8     30    707    7633
Pod Bottom  14.4     30     707  10177
Total upward force =  Pod Bottom - Pod Top = 2544
The pressure at the top of the pod is being considered in the calculation, just differently in the volume calculation.



'Each inner member has less Surface Area and less possible head.'
I am confused by that statement. The water head is the length of the water column starting from the top of the outside water column to the bottom of the water column below the pod. Each surface from outside to in, sees an ever increasing water head and PSI.

Hi Larry,

The head that is able to produce buoyancy is only the portion of the entire head you describe that is the height of the water displaced by the Risers or Pod.  So for example, the head creating buoyancy on the Pod is the length of the Pod (when full submerged).  Water above or below the Pod does not cause any buoyancy.

Each inner member must be a bit shorter than the one surrounding it.  Therefor each inner member has less potential head than any outer.

Thanks,

M.

@LarryC,

Here is how I would have done it.  I'm for whatever way that works that anyone can understand, however!

Here you can see that each Riser and Pod are adding to the Buoyant Force in a straight forward fashion.

MrWayne : Greetings from a fellow Okie! I would like to give you an idea for the use of your device. As you know each time you convert energy from one form to another you lose some. All around me sit thousands of oil pump jacks running 27 / 7. They each have a huge transmission and electric motor just so they can bob up and down. Your unit bobs up and down from the git go and should last for many years. No conversion needed and a ready market where you are at. They pay a high price for electricity and sometimes have to pay a fortune just to get lines put into the oil patch. The unit you sell to them could be very simple and easier to construct.


Another market would be 100 kw units for the local electrical co-ops to use in distributed generation. The Gov has shut down coal fired generator  plant expansion. The co-ops are owned by the customers and are some pretty sharp cookies. Our co-op covers four counties and has been operating since the thirties.
