| The outer
displacer cylinder is a bean can. The inner displacer piston is a chopped
down PVC glue can. I had to use cans that could be soldered. Everything must
be sealed air tight to work properly. |
Here is the
displacer cylinder after the lid was soldered on. |

Upgraded with
new aluminum parts
I added a coiled copper tubing water cooler.
The tubes go to a very small pond pump sitting in a bucket of water. |

The power piston cylinder is a aluminum tube that was cut off a Mountain
bike front fork steering tube.
The power piston inside the cylinder is a copper plumbing end cap used to
cap off the end of a copper pipe.
The displacer stoke is about 1.5", the power piston stoke is about 1.25" |
To do
list:
Cooling experiment #2: Get rid of tin cans and make a nicer displacer
cylinder with a solid hot cap on the bottom and upper half that has cooling
fins.
Cool the fins with a flywheel that is machined into a fan blade shape. |
