Mathematical Analysis of an Ideal ZED

[TinselKoala]

Give Kevan Riley a call. I found his phone number for you, it's a matter of public record. Of course maybe the initials "PE" don't mean in Oklahoma what they mean on this side of the Red River. Maybe he's the high school PE coach.

I would love to hear his explanation of why, in November of 2010, they told prospective investors that they would be able to install a 50 kW working unit in three months.... but have never managed to do so. Not even 20 kW... not even 10 kW..... and we still have seen no proof of the "5 HP Net" thing nor have we gotten any answer to minnie's question.

MarkE,


Flat wrong?

Yes indeed Larry: flat wrong, even in your latest spreadsheet you labeled a column "Stored Energy in Ft Lbs" that calculates values that do not represent such values.  That is indeed: flat wrong.

It has always amazed me about the Physicist wannabees on this site that think they know better than actual working engineers including a hydraulic engineer. They do use P average * V and F average * stroke when P or F is linear, that is just common sense.

No Larry, it is not common sense and it is incompetent for an engineer, particularly a hydraulic engineer to say that P average * V equals energy without qualifying that to very limited circumstance that do not apply here.  Use the wrong formula in the wrong circumstances and get the wrong result.  Insist upon doing that after having pointed out is just incompetence or worse.

So, what is wrong with the Stored Energy calculations that I added for you. Every time you said a calculation was in error, I've had to explain to you why it was correct.

No Larry, each incorrect calculation I have pointed out was in fact wrong.  You still insist on relying upon the same invalid premises to obtain the same invalid results.

State where it is now incorrect and I'll fix or explain why it is correct, then you can tell all why there is no excess energy.

We have been through this before:  The stored energy in each of the four columns is separately obtained by integrating F*ds for the respective columns.  The work applied is obtained by integrating F*ds applied to the input.  You can insist on using incorrect methods and get the resulting incorrect results all day long.  And as the time has come and gone to show that the supposed results are correct in a physical embodiment HER / Zydro of which you count yourself a member have seen that the embodiments do not reflect the results of the calculations you show.

I trained as a professional mechanical engineer at a reputable university for 4 years. I don't claim to be an engineer now however as my speciality is software development.  During the time I studied engineering however I developed more than enough comprehension to understand why the ZED system cannot possibly work as claimed.

I will state again, Any professional engineer would agree with me that this machine does not work as claimed. Those who disagree could only be described as manifestly incompetent to retain the title 'Engineer'.

So I reiterate, who are these engineers and to what professional or regulatory bodies are they affiliated? It's time for them to put their reputations on the line.

Any shareholder who relied on the expressed opinion of a professional engineer for their decision to invest in HER/Zydro can sue that engineer for professional negligence.

Here is LarryC's latest spreadsheet with decomposition and reduction.  Larry is free to defend the physical basis he thinks justifies his model.

markE, can you attach xls file

thanks
