Engine no 14, 'The Buoy'

This engine is a Ringbom engine with the displacer at the top of the cooling plate. The advantage of this construction is that the temperature of the cooling plate is lower, and we do not have do deal with the heat rising from the heat source.

A disadvantage is that the heat transfer at the top of the displacer is more difficult. The heater head must fit very accurately on the displacer cylinder to transfer enough heat to run the engine.

The engine runs on between one and three tea-warmers, but also on three, depending on the speed required.

The number of strokes per minute of this engine varies between 60 and 250. For a change I mounted the heavy flywheel of 3.5 kg horizontally and it runs on a steel ball. The driving mechanism is placed in the flywheel, which adds a new feature.

This Ringbom engine has again been made with a balance spring. This time it works as a pressure spring. The engine is named 'Buoy' because it closely resembles a lighthouse or buoy with its light at the top.

I tried to give this engine the outline of a skeleton so that it looks less massive.
It was also my objective to move towards kinetic art, with the motion at the centre; in this case the balance spring and the driving mechanism of the flywheel.

Very cool variant! I like the vertical flywheel a lot; you could gear it down and perhaps play a 33 1/3 RPM LP. Imagine that, a Stirling record player!

There must be very good bearings.

hi sorry but im curious + a little stupid xD

so watersteam powers this device?

and are they just as powerfull on a larger scale?

[TheVisser3]

@robinhooodvsyou Brass is a great bearing surface, im guessing thats why these are all made from brass, all they would need is a tiny amount of oi,l if any at all. plus it makes them look awesome

[felderup]

@robinhooodvsyou maybe the bearings are rubies... lab rubies are dirt cheap these days, so the benefits found for watchmaking can be given to other things...

[superfunnyman123]

this is amazing! do u sell these?

[ivankoran]

i wanna hook it up to a blender....

[KayukoClan]

That is AWESOME

Have you tested it under a load?
