Mathematical Analysis of an Ideal ZED

[TinselKoala]

   Hi,
       the reference to hydraulic accumulator is a load of crap. You can't store energy in a
   non compressible fluid. Hydraulic accumulators are gas or spring sort of things and are
   used to even out the flow in systems. I suppose a water tower is a type of hydraulic
   accumulator, but look at how high you have to pump the water to be able to store an
   appreciable amount of energy.
                                       John.

What's the problem? As long as you can get more volume out of the accumulator than you are putting back into it, everything will be fine. Heron of Alexandria even knew that much.

MarkE,


Impressive. I'm not anal enough to review, unless someone brings up an issue. If anyone would like to check, it is easy to see all the formulas at once in excel by pressing Ctrl`. The accent is next to the 1 key.

Larry, you can easily just plug in the final formulas into a pair of cells, referencing the corresponding source cells and see that you get the same answers so long as you don't muck around with the ring diameters / gaps.

Some of the Pressure left in a first ZED at the end of its "power stroke" is allowed to "Free Flow" to a second ZED that is at the bottom of its stroke and therefore at a lower Pressure.  This equalizes the Pressure between the two ZEDs and requires no additional Energy.  But it does not bring the second ZED up to the full Pressure necessary to perform its "power stroke."  So additional Energy is required and is called the "Flow Assist."  The Energy for the "Flow Assist" is a recycled portion of the excess energy that is supposed to be harvested during each "power stroke" where the rising ZED is pumping fluid under pressure into a hydraulic accumulator.  The harvesting portion of the system is not being shown in the spreadsheets currently being analyzed, AFAIK.

As has been shown several times, allowing fluid to flow from a column filled to some height H1  to a second column H2 such that the ending heights equalize at an intermediate height H3 loses energy.  For the HER/Zydro claims that creates a deficit that they then would have to overcome with whatever it is that is supposed to be over unity in their process.  Unfortunately for HER/Zydro, there is nothing over unity in their process.

  Hi,
     let's try a little mind experiment. Say you had to stake your life on either the laws of
     physics being right or Travis's Overunity being true?
         I know which option I'd plump for, which would you choose?

The comedy here is that Wayne Travis, Red_Sunset et-al claim to have a found a way to breach the conservative nature of gravity.   No spreadsheet that relies on gravity being conservative, IE treats the GPE of a mass the same based on its height the same no matter what its history of getting to that height happens to be, is going to show such a non-conservative behavior.  So in order to buy into the cult's promise of 72 ever flowing water towers one first has to find a demonstration of this non-conservative gravity claim.  No one at HER / Zydro has, or ever will come up with such a demonstration.
