What is the longest cylinder you ever seen on a Stirling Engine?
So far I have found the Huxtable hot air engine https://www.olds.com.au/stirling/ but there has to be something longer.

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
The INDIGIRKA-2 looks great! 50Watts and a warm stove to cook on too. I'll call back with the results of my own experiments. I'm hoping I'll get around 8Watts from my 10 TEG array, which will be around 1/4 the physical size of the unit on the INDIGIRKA-2. I will need around 50Watts eventually, if I...

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
Another one? During research I checked with ChatGPT (make of that what you will) that wrote: ''During 1950/1951 the engineer/technician Gerrit de Groot was fatally injured when an unexpected explosion occurred during a test of a high-pressure hydrogen Stirling Engine at the Philips laboratory in Ei...

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
Another one? There seems to be only one alleged or rumored anecdotal case of some such explosion, supposedly at the Phillips lab. Apparently not reported by the lab itself. about which practically nothing is known, who was involved, actual pressures involved, circumstances etc etc. Correct, that wa...

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
There were, I think, a number of Stirling engines built that were self pressurizing with atmospheric air. They would start out relatively low power, running an air compressor of some sort and gradually build up pressure and thereby power. I think "Jim dandy" was the name of one, semi- DIY...

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
The best performing FPSE/SE's in general seems to always have another working fluid, and/or expensive, complex. What happened to the KISS-method? KISS is good, but in the case of Stirling engines it's also big and heavy, and wears out its linkage bearings too quickly to send to space. Finely tuned ...

TK motors has some DIY small motors that are quite interesting. . https://m.youtube.com/@tkmotors991/videos Steam engines are easier but require constant attention baby sitting the boiler. He makes great SE's. Always amazed how fast they go considering the materials he's using. Imagine what he coul...

... @Tom - Yeah that is unfortunately how I feel about the SE industry in general, a lot of claims; not a lot of long term verified performances . .... It seems there was.

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
Battery charging works best at amperages reflecting the capacity of the battery. Car batteries at around 10 amps. 2 is considered a finishing or equalizing charge rate. Less would be a "trickle charge", at best. Trickle charge isn't usually enough for a good charge. Furthermore, lead acid...

@Tom @Fool
Agree with Fool, I read that for optimal charging, one should aim for a voltage between 13.8 and 14.4 volts, known as the 'float' or 'trickle charge' voltage, to safely and efficiently charge a 12V car battery.

Re: Does a medium sized SE exist that could charge 12 V car battery properly?
8 amps would be a good charge rate for a 12V car battery. That's 12*8 = 96 Watts An unpressurised SE using air making 100W might be fairly chunky unless its of Andy Ross level sophistication. Possibly bigger and heavier than my 40 year old Honda EG550 sidevalve generator, which will make 450W conti...
