The power piston (NOT the one over the flame) is steel to minimize wear.
I'm not 100% sure about the slave cylinder but I remember it being aluminum. It needs to be light because reciprocating mass is counterproductive. Since the slave piston doesn't wear, you can make it out of almost anything, but you are better off if it has a small thermal capacity otherwise it can get hot and make it much more difficult to cool the air for the second half of the cycle.
One of the more notable attempts to commercialize this technology came from Philips where they made a Stirling based generator to allow use of electric devices like radios in places without a reliable power source. I believe these were powered with Kerosene and used compressed air to help start the engine. The engine would run a blower to help increase the heat provided by the burner.
With today's transistor radios it would probably be pretty easy to meet the power requirements of a radio
ok why are these not on a larger scale?? i mean i could use one to power a radio from a bonfire in theory correct? just have ice water from my beer cooler wrapping the cooling side and a bed of coals or direct fire under the hot side? just an idea. if anyone can build one i would buy one for up to $100 good luck and get back to me if you can :)
So the bigger the temp (hot area - cold area) difference the better ? Im planning to try and make a model to find the best rendemend. My idea is to make 4xstirlng beta or gamma and connect them together on a parabolic mirror dish. instead of 1 big i want 4 small. Also a close cooling system and temp controlers to monitor and adjust so i can achieve highest possible power. This whole thing will be attached on a PMG alternator 2 or 3 startors.. big challenge but i like challenges...
Correct! the larger the temp difference the more power you get. The reason is that with a bigger temperature differential you get a greater heat transfer rate. Remember that getting a better flow of heat in and out of the engine is key to making this work.
On the hot side you want to collect energy efficiently, on the cold side you want to disperse it quickly. Insulate the hot side from the cold, and use thermal grease on other connections to keep the heat flowing. Good luck!

The piston is made to be a tight seal, but yes, you are going to lose a little air from around the piston. However, the piston is only under pressure for half of the stroke the other half, it's experiencing suction. In theory, they should balance out.
how do you mack it

Thank you for your interest: The interior of the motor must be lubricated with oil?

Hi Can anyone tell me what material is the piston?
That supports the cylinder temperature?
Thanks, Jorge from Argentina

I have no idea what's going on. Look for the differential gear from the 30's video to see how a "how it works" vid should be made.

does the sterling engine have the best thermal efficiency of the heat engines?

That's so cool!
I spent the longest time trying to figure it out, and I stumbled upon this video.
Thanks so much for the explanation!
Great video =]

Dont we loose air or gas through the pistons hole for the arm? or from whatever slightly leaks around the piston?
