Re: I want to build a high efficiency Stirling electric generator

Where can I find something like this but made of elastic metal? I want to compress the air, but without the piston.
Or if I can't figure out how to make it?

Re: I want to build a high efficiency Stirling electric generator

I don't know if it's true or not, but I'll share some of the answers in the video above. Answ.jpg The problem is that it is very difficult for an amateur to do what is done industrially or by a company. For this technique to be useful, it must be superior to its alternatives. Industrial stirling has...

Re: I want to build a high efficiency Stirling electric generator

How can we compress the air without the piston's friction? to increase efficiency? Something like this but made of elastic metal to withstand the temperature. Where can I find or how can I make something like this? (but made of metal) https://noriel.ro/media/catalog/product/cache/c682e6120e627a95f4c...

Re: I want to build a high efficiency Stirling electric generator

It has been a long time since the discussion started and I did not take the first step in the practical realization! https://www.youtube.com/watch?v=z7lUzKfdHd4&t=305s Is this it? I didn't understand where this air conditioning compressor came from. Where do I buy it? What other vehicles have a ...

Re: I want to build a high efficiency Stirling electric generator

Do I need high pressure for high efficiency? 100atm? I'm disappointed because I can't have such pressure ! Strangely, the supplier of such generators no longer produces, is bankrupt. And here you wanted to change the subject. https://www.youtube.com/watch?v=j7Ja05DKZsk Even a large company like Phil...

https://www.stirlingengine.com/generators "Stirling Engines in Cars – A Bad Idea There was a big government-funded research project to put Stirling engines in cars. But, Stirling engines intrinsically ACCELERATE SLOWLY and they’re DIFFICULT TO REGULATE efficiently (go from idle to full power qu...

Re: I want to build a high efficiency Stirling electric generator

"I personally find it rather perplexing and frustrating that something that can be built as a small model, out of tin cans and balloons [...], isn't more readily available to buy." Either there are interests, or we do not understand the disadvantages, as with the fuel cell which are many k...

Re: I want to build a high efficiency Stirling electric generator

From: https://www.intechopen.com/chapters/62541 "The estimated Stirling cycle efficiency (heat to work) is about 45%. The system efficiency (fuel to electricity) is around 38.3%." There was a company that produced such generators and sold them, but I think it went bankrupt. Then NASA Stirl...
