This question is for those who have metronome Engine experience.
Q: Am I right in thinking that the heavier the displacer is (plus magnet) , the longer the hose has to be?
I would like to make some with linear alternators on the displacer shaft.
Q: Also can the hose be vertical (straight up) ?

I have only gotten the water piston version to work ( pringles can version) thanks to mrsamodelkin and it doesn't go fast.

Engine is much better with air.

Thank you.
I also think I may try magnet springs , might work to counter balance mass of magnet.
Thanks for speaking English, I appreciate it. I am only a one language person. Need to use google translator.

@tibsim
It looks like the displacer has to be denser than most stirlings to assist to compress and rarify the air in the gas diode ?
Also more close fit to the cylinder?
What do I need to do to get the shortest hose? Smaller diameter?

Two things.

The hose on the metronome could be the long pre- coiled plastic air hose like the picture below.



Question:
1. Could the long hose be replaced by a short pipe connected to a diaphram/ membrane to save space?

Here's my plan.

First engine always must be perfect same than description.

?

Does anyone think this would work so there wouldn't be such a long hose?
