KENDERV engine: closed circuit heat engine

Not exactly that proves their mentality.
It would have cost them what to LET the copyright?

Tip: go your way (once again).
After you do what you want.

about joomla:

Joomla is an open-source CMS under GNU / GPL license.
What is the GNU / GPL license?
This means that the software is free: It can be used, edited and redistributed freely.
However, if the source code can be modified, this license entails two major obligations:

1. Do not erase the copyright in the files
(in addition it does not change anything for the user: he does not see it unless he looks at the source code of the page he visits)
2. Do not change the type of the original license.

A third obligation, more "philosophical" than legal, would require that Joomla !, be cited by a link, on the site created with (by default there is one in the footer, which can be deleted from this place). This point divides the French-speaking community into two schools: those who are for absolutely leaving a link as a thank you for this program made available to us, to make it known more and thus participate in its development, and the others since it is not a legal obligation.

on the other hand I do not say that not let the copyright would have been a luxury, however it is obviously investors, ie people who want a very fast return on investment ... how does to go through open-source surprises you?

Is it a guarantee of incompetence? They are thieves ? who steal what? the technology they are trying to develop?

the purpose of this forum or rather forumers who come to this site what is it? break grain on any attempt to change ???

or just some people who just turn their thumbs while others dig themselves for years to find solutions ...

I find it pathetic and insulting of you Christophe to say: "Go your way, this invention is pure bullshit, I want for proof they use Joomla without leaving a trace on their site ..." ah yeah? are you sure ? so already as you noticed it is the basic template which is used ... we can do more discreet! and above all they use joomla taking into account the obligation to leave the copyright registered in the source of the site ...

finally, it's not even that bullshit that makes me jump! it is to see how easy it is to judge (without understanding anything) the work of a lifetime!

Thank you for so much respect!

Uh, what's your problem with my comment? Do you have actions at home? Did you contribute?

It does not prevent, I do not know about you but I saw too many scams on the net selling magic and revolutionary engines ... besides there are dozens presented on this forum...

And on this forum, I vouch for it, we are not here to dream, let alone to do the hoist of a real investor on a hypothetical invention (you can do a search, we have repacked more than one), but to make concrete.

Serious investors do not take Open Source but pay a few thousand euros for a real site ... I deduce that they especially want to invest other people's money ... with a quick return .. . like "everyone" ... obviously ...

[Christophe]

Ah, I missed an important message from Bham ...

So myCousin = Kenderv?

I may have gotten excited a bit so apologize to me

But question: where are the 1er results of a first prototype tested by a University or equivalent?

Because for the moment for me the content of your site (.pdf included) is virtual, some drawings, photos and some technological speculations with pretty pictures of cut. For me at the moment there is not much else ...

Have you assembled these 2 parts at least one day? It looks very much like a DIY based on a Turbo ...turbo turbines are turbines operating at low pressure but high flow ... the opposite of what is explained on the diagrams (200 bar) so how do you explain this?

[bham]

Christophe, I still find you virulent and not very objective about this product; we do not propose to buy it in the immediate future, we just say that Mr Cousin wanted to develop an idea, he did what it took to become known investors and some of them seem to believe it.
If not, would such a site exist?
Well, I already know your answer, it's bluff, ... etc.
But do you think it is interesting for investors to make a site only to make people dream, or to make themselves known. Moreover, for the moment, they do not sell anything.
A huge alternative energy market is opening up and some investors are hoping to make the most of it; and so much the better because otherwise nothing would move.
So before giving a negative opinion, be patient, things move slowly, Mr Cousin will probably present us a video of a proto (in September), unless he finds the greeting on too sectarian econology, attitude which could well, in the long term, harm forum.

[Christophe]

I do not say it's blue, I say it seems very light ...

Before asking for money via internet and contacting the press, we make a prototype that works in his garage.

Even if this proto has only 1% of the final product performance. Ok or is it this proto? Because here I have the impression that we find ourselves in front of a new Mikhail ...

I hope I'm wrong.

Otherwise I prefer to be sectarian and put some people back to me than to advertise things that do not exist elsewhere than in the minds of their megaloman inventors who believe they are saving the world... especially if there is a fundraiser at the key.

I gave enough in this genre. Look here is another one: https://www.econologie.com/forums/projet-sym ... t5508.html

Hello everyone,

I see that things are moving on Kenderv's machine, I went to see his site and finally we understand "the principle".

This is a closed circuit of dihydrogen close to the operation of a gas turbine, with a compression turbine (the small compressor that returns to the exchanger) and an expansion turbine (the large 200Bar-> 20 Bar ).

"This standard sized system can produce 39 kW or 53 bhp, by running on the temperature of the surrounding air only"

But there is a fundamental conceptual flaw in this system. There is a hot source (the ambient air that gives its calories to the high pressure fluid in the exchanger), out there is no cold source (a source to which the fluid could yield calories at low pressure). When the H2 relaxes, it comes to -250 °. For the system to work, it would require a cold source of at least -260 °.between 2 turbines.. We flirt with the absolute zero.

All this is not a technical problem, but primarily thermodynamic. It is impossible to create mechanical energy from a single source of heat (a large hot thermostat). It is absolutely necessary another colder source (a big cold thermostat). Kenderv's machine did not which the hot spring

These are basic notions of thermodynamics that Kenderv seems to have neglected. In order for his machine to operate on the basis of the pressures / temperature at the end of the relaxation he indicates, a cold source close to absolute zero is required ...

It's very ambitious on Earth! In space it is discussed because we have the sun and the very cold vacuum

[Christophe]

You went very far in the analysis Remundo (with so little data I would not have dared) ... well done but, a pity for Mr Cousin, because it would confirm my assumptions stated above.

I'm waiting for his answer....

Hello everyone, and Christophe,

After my last intervention, one of the forumers econologists wrote to me to offer me documentation on "the Sirius gas and heat project" that I did not know.

I then made "my gogole" and I found it more relevant:

Good evening everyone.
The price of oil explodes. This is a chance for the hexagon and the planet.
Why?
Because the hexagon in question can become a leader in the automotive field
"zero liter of fuel / 100 km and Zero oil, Zero decibel planes"
For my part, I think that if an automaker puts on the market a powerful car (900 KW) using a free and non-polluting energy, it will do business. It is not your opinion?
What is this energy?
Well, you all know that a heat engine uses heat to work, otherwise it would not be thermal, but electric, hydraulic ect ect.
The origin of this heat may be any, combustion of oil, coal, nuclear hearth ....... or atmospheric heat.
For example, at the pressure of 101325pa, 15 ° C, 1 kg of air can release ~ 210 000j in the form of heat (low temperature, liquefaction of the gas).
The proposed engine uses this heat.
How can this heat be extracted from the atmosphere?
It's very simple, just cool the air.
Yes, but to cool the air, you need a cold source, should you use the fridge pedal grandma?
No. The air at the exit of a turbine is much colder than at the entrance because the turbines transform the heat of the air which is spread there in many good steam horses.
Maybe, maybe you'll tell me, but make an engine?
It's childish! , it suffices to design a turbomachine operating at temperatures
If you want to know more, I am at your disposal and a "cheaper free" doc
is available, but it seems it is very creepy (I demonstrate by calculation what I say).
Regards Gas and Heat

By the way, I do not understand this "frenzy" of Sirius to offer "cheaper free" documentation. . Whether the "designer" publishes his calculations (false or based on false assumptions ...) or does not publish them ...

In short, it will allow me to answer at the same time as to enrich the subject.

What is striking in this text is on the one hand the similitude with the project that Kenderv presents on its site, and on the other hand, the illusion that the expansion of a gas from 20 ° C to -250 ° C constitutes in itself a cold source for operation.

Precisely, it is absolutely necessary heat exchanger in the cold and low pressure zone with precisely a thermal source outdoor to the system guaranteeing the heat transfer fluid to give a little heat to the cold source.

These are only turbomachines with one source "hot" at ambient temperature and another (absent ... by mistake!) Cold near absolute zero. We slipped into the temperature scale from 1000 ° C / 20 ° to 20 ° C / -260 ° C

For fans of thermodynamics, the maximum theoretical yields are respectively:
1-Tfroide / Hot in Kelvin:
* 77% for 20 ° C / 1000 ° C
* 96% for -260 ° C / 20 ° C

Do not delude yourself on these yields ... especially that of "absolute zero": there is no cold source on Earth at this temperature.

In addition, on the technical level, the difficulties in holding the parts are still there: the "softness" of hot steel is replaced by its brittle nature when it is ultra-cold. But that is only trivial compared to the pure and simple negation of the 2nd principle of thermodynamics.
