Heron's Steam Engine

Here is my design that I would like to make following up on Heron's Engine.

nice design. 

any thoughts on how it is to be filled while in operation?
or is this like a 1-shot deal, and refilled after the water is gone and the machine stops??

Hi Smoky.

I added a little extra detail to the design by adding an inverted heat trap in the center of the cylinder.

If we wanted to have an automatic refill design we would have to think about it a bit, swivel valves and possibly Thermostat valves to sense the pressure in the bottle and to automatically refill when needed.

something to think about.

Nice work,

I understand everything in the design except for the levitation magnets.  The bottom magnet is fixed, while the top magnet is levitating, but I'm not sure what their purpose is in the design.

This looks like a simple build.  I'll put it on my to-do-list.


Thanks,

Hi GB.

The top magnet is glued to the bottom of the fill valve and acts as a magnetic bearing which rides on the lower magnet to help reduce rotational friction of the copper cylinder.
