Intro: Marble Stirling Engine (rotating)

The Image shows a rotating type stirling engine where the marbles are used as displacers and glass syringe is used as power piston. This is also another simplest engine which could be done in hours using available material.

Material used:

1. Glass syringe (power piston)

2. Rubber cork

3. Glass marbles(5)

4. Old CD (Flywheel)

5. Refill (connecting rod)

6. Testtube (Displacer body)

Other:

1. Fevikwik

2. Araldite

3. Candle

Here is the end result of this engine.

Step 1: The Other Parts

Here one important thing to be mentioned, I have used a small bearing to hold the flywheel. The bearing diameter is about 4.7mm. The others are self explanatory from the images.

I have not used stand to hold the moving part since i was trying to find the centre position so that i can attach it to a oscillating stand.
