VincentG I already acknowledged that the JT effect requires viscosity. Ideal gasses have no viscosity. What more do I need to say. This has nothing to do with ideal gasses.
Tommy is injecting a straw man into this thread because he either is a paid troll or ignorant of how to logically and politely discuss something. Sorry he has done so. It was my attempt to point out the simple errors in your brainstorming. He's the one that put forth the lies. Anyway, my points are still valid. Please consider them for your own benefits. Ignore Tommy he is so often wrong and more often vile when his errors are pointed out.
Tommy, your first comment is far from the truth. I know way more than you give anyone but yourself credit. You are the uneducated here. So much so that any educated scientist sees right through your experimental flaws. Your refusal to make the simple measurements required means you know it and are deliberately avoiding gathering that evidence. For all we know you already have discovered your error and refuse to disclose it. How is your butane refrigerator going? My guess is you failed and now won't tell us that Fool knows more about refrigerator scams than you. Imagine knowing less than this Fool.

Yes cooling, implying the rejection of heat by a temperature difference through conduction, before and during compression makes compression easier. Smartest thing you've said in a long time. Except gas doesn't "contract" it always fills the cylinder with positive pressure, requiring force outside the cylinder to compress it.
VincentG is on a wild goose chase and suggesting/requesting help from us on an effect that is non-existent inside any enclosed heat engine. I've given that help. He is daydreaming. An okay process for brainstorming. It is not pioneering unless he has a demonstrable machine or theory. Theorizing requires data and complete logical connection to other theories, brainstorming doesn't. He said it was not worth his time to pursue it, but proof would be that it breaks the second law. A circumvention of the second law, would allow a perpetual motion machine of the second kind. Again, that breaks concurrently the first law.
Friction is your diversion Tommy. I'm pointing out that the idea is counterproductive, with or without friction, drag, orifice, or capillary tube. Expanding the gas without work so it can be compressed more easily is an oxymoron at best. But I point out, it will have expanded, loss of energy, with little if any temperature change, so little regain if any. Easy to see if you know how to read the graph I supplied. And it will then take more energy to compress, destroying and hope of improvement. Proof will be that it runs less efficiently.
But you all, don't let knowledge get in your way of a fun inspiring waste of all the loads of free extra time we all have built up just to use on a wild greased goose chase. Please have fun. While you are at it, put grinding powder on the piston so the friction will add to the 'heat of expansion', so that more heat can be converted to work, making the engine run even cooler so it never needs to reject heat, or absorb any either. Self heating is the way to go. Which is what you all are insinuating with the breaking of the second law. Self cooling implies self heating can be done. Bollocks.
