Marble Stirling engine

This is a marble-displacer Stirling engine. The rolling marbles act as the displacer, which are transferred from the hot end to the cold end by the tipping of the test tube. The tipping of the test tube is caused by the piston being connected directly and rigidly to the crank disk and flywheel.

its an brilliant engine.can i use glass syringe as a piston.

[1967geezer]

Yes, as long as it has a uniform, round bore.

[candylady]

how did you seal the piston?

[1967geezer]

It is a very close fit in the cylinder, close enough to be almost airtight but still slide freely.

Incredible engine. Where did you get the piston/cylinder set? I know airpot sells them but they are expensive.

[1967geezer]

Left over from a project at work.

[24ursus16]

What are the materials that you used for the piston?

What are the materials that you usead for the piston?

[Robbskunky]

Do you have a design plan that i can look at?

[nstahlable]

@1967geezer would it be able to go faster than this?

[sakunoandryoma]

I'm using this as a project could someone please tell me how it works and what materials it have please give alternative ones too i want to save money this one looks expensive

thanks for helping me IN ADVANCE

I think I like this Stirling more than any other

[imikewillrockyou]

That is really an amazing concept. Marbles as the displacer?

[TheGoodInventor]

fantastic



[gildete88]

onde conswguir o material para fazer este motor?

[eldiablo9000]

is that steel wool you use??
