@Tom@Fool Be decent, and if someone tries to PM one another don't air your dirty laundry. Show some dignity. Ask yourselves, would you guys still type these things if you guys knew an impartial admin would ban you.
@Fool, if this thread itself and this viewtopic.php?t=5415 isn't proof enough of a man that puts his time and MONEY towards the furtherment of hot air engines, I don't know what is.
@Tom, when it comes to Fool the man knows his stuff. If you would create another forum and not allow people with differing views like Fool, that is not a forum I would like to be a part of. You would create your own echo chamber.
My main point is we're all passionate about stirling engines, I for one would like this community to grow. Members of this site are literally dying off. This infighting does nothing but fracture it even more, when the internets most popular stirling engine forum is at it most crucial stage. Rant over.

Spacefog_, well said. I came to this forum because it seemed to me that Tom was a beneficial element that was asking for help in understanding classical theory. I now think he is only soapboxing his agenda with those that agree with him.
He has strived to have me banned, all while calling me and others names, and attacking there persona rather than their science.
Any website he moderates, let alone constructs, will fail to contain fair and open scientific material.

He never banned anyone at my request, he banned "fool" and a "nobody" for being rude and disrespectful to HIM. He suspected fool and nobody to be one and the same.
Nevertheless, some moderation is necessary in EXTREME cases and IMO "FOOL" is an extreme case who refuses to let any group of people interested in pursuing a subject carry on in peace.
Fool has made his case but refuses to let it rest or allow others to carry on. He is deliberately derailing and interfering with others peace of mind and enjoyment of the site which for the ten years + that I have been here has always been light and fun
Since fools arrival it has turned into a war zone.
Further, IMO Fool knows only one thing and that is rote "classical" textbook thermodynamics that certainly has its place and usefulness but is not everything.
He has shown incompetence or complete ignorance on more advanced areas such as non-ideal gas behavior, Van der Walls forces, Lenard Jones, and many other departments. His viewpoint is completely myopic and archaic aside from being an arrogant prick.

Tommy, should I look up all the wars you started? Your back stabbing AlpahX and others. You don't like me because I reflect your own argumentive techniques. The difference is I strive to stick to the science, then to point out your rudeness. You seem to fly off the handle with cherry picked examples, wild guessing, incorrect fumbling of mathematics, bashing of great men, lying, name calling, cursing, and general misunderstandings. You've failed to comprehend and learn simple science. And you have resorted to lies and denial of obvious scientific fasts. Such as your lie that gasses attract, or contract. They don't. They push, it's called absolute gas pressure, as measured between the gas volume and a vacuum.
The only war here is the one that you Tom Booth has with his own belief system and science. You are your own worst enemy. I just don't put up with those lies. I only put forth corrections to the science that is being erroneously bent, and reflect your own hostility. My apologies for not being perfect, I mean for being human.
Sorry that you just posted a pack of them. Logical fallacies appear to be your friends and your style.
In other words, Tommy started the war with science, and it looks like he won't end it until he thinks he's the one that has figured it out. Unfortunately that has set up a personal conundrum. He now needs to lie to support his lies, or lie about how he's learned real science. Either way it's lying.
Hint: You are not fighting me. Science is being presented to you, you just need to understand how to use it. That starts with trying to use it, not denying it as you seem to do. Start thinking how can these engines work if gasses always push, and there are inside and outside gasses most of the time here on Earth. And stop lying about and denying things to yourself. Let all the real data in.

Re: Domain expiration

I guess you have no clue as to how far a molecule needs to move in comparison to the effective distance of molecular attraction. And how weak Van der Waals force is.
Hint. If the gas expands by increasing the volume by four times, the temperature drops and pressure drops, yet there is still positive pressure and you can't explain how the molecules get larger.
You are plainly in denial of facts, data, logic, science, and mathematics.
Molecular forces drop off by 1/r^6. You don't understand that.
Gas molecules don't return because of molecular attraction. They return because of molecular repulsion. They bounce of other molecules.
Bouncing is pushing.
Stop cherry picking the science and using it incorrectly. Start looking at all the data and science.

Re: Domain expiration
According to the information relating to the Lenard Jones potential, your "bouncing" ,or molecular repulsion is only effective during a collision, or when the electron clouds of two gas molecules overlap.
The effective distance of the attractive forces on the other hand, though small and falling off with distance are virtually "infinite'.
Therefore at any distance greater than actual collision or overlap, attractive forces dominate.
In general the gas molecules maintain a distance close to where the forces of attraction and repulsion are balanced, oscillating or "vibrating" between the two (too close or too far apart) unless subject to some outside influence that disrupts the equilibrium.

However, there is something even worse going on with your description. You completely left out the force called centrifugal force. The force responsible for breakaway from orbit, caused by speed. Specifically the speed called escape velocity, or boiling velocity. Above that speed the molecule is no longer restrained by the attractive force. It is free to travel forever away, unless something constrains it, like bouncing off a wall, or bouncing off all the molecules between it and the wall.
Centrifugal force plus the equal and opposite force centripetal force, are the two complimentary forces that keep a string tight while an attached mass is spun around. Closer orbits produce more force. More distant orbits produce less force. Faster more force. If the string breaks it is tantamount to becoming a gas molecule. Like the rock and sling David used against Goliath.
This revisited becomes, further orbits, more speed, have smaller molecular forces, as described by Lenard-Jones. So the further out the lower the speed needs to be to be above the escape velocity. A lot less. At boiling velocity, molecular forces become moot. Size has some influence at temperature and pressures close to boiling, but very insignificant at ideal gas law conditions.
You are producing red hearings. Things we don't need to chase down.
The following explains this but not very well. It will take careful thinking to understand it. Search for more like it. Solid liquid gas.
https://www.chem.purdue.edu/gchelp/liqu ... acter.html
"move freely at high speeds." Is the correct description.
Lenard-Jones can be used to model this but, it's effect, compared with the kinetic energy, will be minimal. It may even make the overall simulation less accurate.
I have put this forth not in opposition, but in correction to the description of science you put forth. It is additional information.
.
Science requires you to stick with either the forces are "balanced"(aka equal), or one is "dominant" (aka significantly larger). So which is it going to be? Answer: One force is extremely, very very weak and the other is immensely weaker than the attractive, at the average distance of a gas molecules. Neither is significant.Tom Booth wrote:at any distance greater than actual collision or overlap, attractive forces dominate.

I would remove "vibrate" from the gas description, because it is an insignificant parameters. Molecules only vibrate when their forces are in balance, only when solid or liquid.Particles in a:
gas vibrate and move freely at high speeds.
liquid vibrate, move about, and slide past each other.
solid vibrate (jiggle) but generally do not move from place to place.

Re: Domain expiration
It's ignorant crap, not "correction". A twisted and contorted mangling of facts with your calcified opinionations..
Rather that learning new ideas or information in the context in which they live or originate you twist information to confirm with your own outdated and obsolete preconceptions based on moribund scientific theory from bygone days.
