Re: Design/Build One HP Alpha Stirling Engine
Platinum in form of catalyst (sponge), (as all heavy metals in form that can be dispersed), is toxic, and a bit expensive.

Re: Design/Build One HP Alpha Stirling Engine
Of course copper, silver, gold-platinum alloy, platinum, or iridium are the best, but some are not stable at high temperature (such as copper, or the silver), or have some other spiritual element that it discourages the use. e.g. a spiritual element may be is extract too much money from the pockets....

Re: Design/Build One HP Alpha Stirling Engine
If possible is good Nickel alloy, as costantan, that may be is found in very thin foils; nickel alloy is better heat conductor.
Regenerator have to collect and yeld heat faster as possible. The speed of transfer is proportional to conductivity.

Re: Displacer Thickness
imavad, Talking about "good techology level engine". This is my personal idea: for displacer is good stainless steel, has quite low heat transmission coefficient, and may be is found in thin plates. Except if found in very thin pipes I think is good 0.8 mm tick rolled plate, hand bended in...

Re: 200W Stirling Engine Help
Riz, Each has its own system to build the engine, depending on their capacity building, with their money, and fuel or other factor that want to use. The Stirling engine is extremely variable as the form and architecture. An example of the past, that gave exactly 220 W was the "Philips Bungalow ...

Re: Carnot engine
God in his infinite wisdom has placed a limit to the intelligence of men, but did not place limits to ignorance. It was exactly what I meant, "do not tell us". You want to explain how is the Carnot cycle (it is useless, you know it's already been thought of and described 200 years ago, and...

Re: Carnot engine
Welcome Serghiei, I honestly do not know which argument should be established. But you must not be worried, we have had already, (also recently) supporters of many strange ideas. If I understand you are a supporter of the Carnot cycle/engine: Is like claiming that the river water, usually down to th...

Re: A new Stirling engine concept ?
In Italy we say: the mother of fools is always pregnant. Who makes claims about perpetual motion has at least limited knowledge of thermodynamics, which is like talking about motorcycles without knowing what are the wheels. If someone have knowledge of good reasons to oppose established laws of phys...

Re: High compression
As you know this is the site of the Stirling engine. The Stirling engine is, first of all, an external combustion engine. This poses several problems and some advantages. The advantages are that the combustion is continuous , so potentially perfect, something that can not physically be in diesel eng...

Re: High compression
Camerart, 1) The design is your. But more complex is the solution more difficult become extract energy. 2) Pressurization means that engine is closed in a shell, or with devices (compressors) that maintain pressurization: all type of engines can be closed in a shell, or beared by a compressor. 3) To...

Re: beta engine design
Speaking about a car (example a small city slow speed autobus or city car), a small (e.g. 3 kw pressurized engine) Stirling, may continuously supply power to a buffer system, increasing the batteries autonomy (the main part of time of a city car is stopped). The continuous combustion give the lower ...

Re: beta engine design
Is really difficult that is simply a question of variable transmission. The engine do not bears variation on load; variation of load influences the engine rotation speed. If rotation speed goes over standard, the max yeld drops to minimum, and engine stops. May be is necessary a energy buffer also (...
