LTD engine no1 (Low Temperature Difference Engine)

This engine is made from the design of Rudy Mémin. It is based on the engine which was made for The Palace of Discoveries in Paris.
The engine has run on the warmth of the human hand, but it runs much better with the regenerator. So my advice is to put a regenerator in the displacer.

For making the holes I used two different hollow punches. The biggest punch was used for the Scotch Brite, ± 32 mm. The smaller punch was used to make the hole in the displacer, ± 30 mm. To obtain a perfect hole in the displacer this should be done very carefully by hand with a light rotating movement.

With LTD 1 I glued the Scotch Brite sponges with white wood glue. However, by making the regenerator sponge a tiny bit larger than the hole in the discharger it sticks without glue.


LTD engine nr 3

This is a self-starting Ringbom engine which runs on only a small difference in temperature between the two plates. With this engine it is very important to stabilize the temperature because these engines are very sensitive to pressure differences.

When the pressure difference is too big the engine will run in an unstable condition until the pressure in the displacer cylinder has dropped and the discharger can function normally.

The technical data of this engine:
Cooling plate: diameter 220 mm; thickness 5 mm; material: aluminum.
Heat exchanger: diameter 220 mm; thickness of the flange 5 mm; discharger (centre part) 2.5 mm; material: aluminum.
Displacer cylinder: outside diameter 200 mm; inside diameter 192 mm; height of the ring 26 mm; material Plexiglas.
Displacer: diameter 191 mm; height of the discharger 12 mm; material: green insulating foam plastic board, brand STYRODUR by BASF.
Regenerator: 6 holes, diameter 30 mm, shifted 60 degrees in relation to each other in the discharger, filled with sponges of Scotch Brite.
Power piston: diameter 22 mm; piston height 22 mm; stroke adjustable between 12 and 30 mm; material: graphite.
Power cylinder: inside diameter 22 mm; outside diameter 25 mm; length 55 mm; material: brass.
Displacer piston: diameter 16 mm; height 22 mm; material: graphite.
Displacer cylinder: inside diameter 16 mm; outside diameter 18 mm; length 50 mm; material: stainless steel.
Flywheel: diameter 185 mm; thickness 4 mm; material: Plexiglas.

You should publish a book with photos and designs. This book could come with a DVD with HD videos of your pieces in motion. A traveling museum show is another idea. I wish I could see your art works in person. Sterling stirlings indeed!

your hot air motors should be on a museum
thanks for your videos

best regards

Ive really enjoyed watching these little sterling engines run. These are probably he most creative pieces of kinetic art Ive ever seen, not to mention the most gorgeous. Have you ever considered (or perhaps you already have) of giving them little chores to do? Perhaps they could be built to dispense eggs and crack them onto a frying pan, pour a glass, or even make breakfast in the form of a large Rube Goldberg device. You could fill the room with the pleasant melody of a sterling engine musical box, or a sterling record player. Just suggestions, if Im coming off sounding as if I would prefer to see these rather than what youve built already, I apologize.

In my opinion skip the music and put the mic close to the machines, would love to hear how they sound. Good job so far love your vids. .-Pete

Has anyone ever driven an lightweight rotor displacer through an angled universal joint, thereby making it slow down and speed up twice each revolution?  If the two 'hesitations' were at the hot and cold ends, then, in theory, it would produce very considerably more torque at slower speeds.

Hey, that "crazy engine" you got, where does its heat differance come from? Is it stored inside it some way or have you figured out a way to create the differance by some mechanical function?
