It is my belief that Stirling Engines are being suppressed, but not for the reasons or by the 'people' you might be thinking.
The following link is for a Sefton Motors - Melvin engine that is available for purchase:
https://seftonmotors.com/products/volo-one-engine
It has a higher cost per power output than readily available IC engines 1/2 to 1/4 the price and 3 to 5 time the output.
There are several ways ideas get suppressed:
Logical - nature won't let it work.
Practical - it won't work well enough to warrant the trouble of building it.
Constructable - can't be built with the tools and materials we currently have.
Financial - cost more than the work it does, or more than acceptable alternate and currently available machines.
Political - someone of significant power or position suppresses the product because they like someone else better.
There may be more, and finer breakdowns of those given but the idea is that there are many ways to kill an idea.
My point here is that most ideas, that sound good, die in the first logical stage. The person with the idea realizes why it won't work. You can't build an airplane out of water ice and fly to the sun. Sometimes an idea is suppressed in this stage because someone else points out how it is prevented by nature. Your ice wings will melt long before you get to the sun.
Ultimately bad ideas die in this phase because they never will work. I call this a failure. I recognize at this stage failure may mean your idea is completely bogus, or with simple modifications it would work. With a failure it is often hard to tell the difference.
More knowledge can help flush out which way to go, however, a little bit can be dangerous, and a little more can make the true answer clear. Trying to squeeze gold coins out of a sponge fails for very minimal amount of knowledge. Why humans would or wouldn't be able to fly, not so clear nor easy. Birds fly. A little knowledge, birds have wings, humans don't. A little more knowledge, humans are way heavier than birds so need proportionally more wing area, etc...
I started this thread because I felt it was necessary to address the following post by Jack. I'm not picking on you and believe what you have said:
At this point I don't have enough information to make specific comments, I will any way LOL, on Jack's personal experience. So I'd like to politely ask for more information. Can you please clarify on the above with a little more detail.Jack wrote: ↑Sat Jul 13, 2024 4:59 pmI can't bring much knowledge into this discussion, but you mention this point twice and I felt the need to say something about that.
This is a bit of an innocent view of the world.
Having worked at Asml euv, Samsung R&D, and Pfizer I can assure you technology is suppressed left, right and centre. Companies with vested interests have a big inventive to keep the status quo going. One of my projects in Korea was a victim of this. A clear step ahead in technology and Samsung bought it and stalled it. Never to be seen again.
And this was only about led screens, imagine any bigger markets, like engines, and the forces at play there.
Tesla even mentioned this himself in many of his writings.
So no, absolutely not. In no way would a breakthrough mean that years later we all know and use it. It's just not that kind of world.
You seem to be hinting that the only reason for the suppression is the political one? Someone had a product that was earning money, so that a better product woud threaten those people's profit?
The problem I have is, that there are so many other reasons for a product to fail that political suppression is probably very rare, and after the patent runs out, open for anyone.
So in the case of the Zeromotor and Tesla's cold hole plan it's more likely to be the logical reason for failure. This is especially likely because of the more recently known laws of nature preventing it from working in any conceivable way.
The lure of 'free' or at least inexpensive power is too grate for a device to be suppressed by politics. Someone would be building them, similar to the Melvin Stirling above, even though it has massive financial reasons for suppression.
This leads us to niche reasons a suppressed product might still be valid. Even though it is a mechanical and financial nightmare, it still might be able to solve a problem in certain niche.
