It can be more efficient if the air intake is provided in cylinder. Piston can be pushed downwards with the help of air and electric coils.

[@richardturton6900]

$100 WHHAAT!!

[@vaclavtrpisovsky]

At that point, I would expect more polish, such as transparent dust-proof covers on the pistons or a commutator (brush) with less noise and mechanical resistance. Or a 2-phase BLDC driving circuit foor self-starting, even if it meant hiding a PCB inside. Stirling engines are meant to run at low power and make little noise, and all it takes to make an electric one out is an underpowered PC fan. Replace the propeller with a shaft and a cool flywhweel, stick it into a case made of scrap steel and copper parts and you’ve a similar product for much cheaper.

[@Conservator.]

Exactly. I’d expected way less. It’s machined in a very crude way too.

[@shayhsopwagqehghggtfyggty2635]

Of course, a liquid fuel 40cc engine (0.04 Litre engine) costs $190.66, a electric powered 40cc engine costs $99.66 in U.K.

[@westelaudio943]

Economy of scale. Not many people will buy a 2 "cylinder" solinoid engine. I have a model steam engine (kit) with about the same level of complexity and it actually did cost me more than that (and that was in 2007).

@@vaclavtrpisovsky I agree. For this price I would expect more.

[@vaclavtrpisovsky]

What is the average current draw at the minimum voltage you can reliably start it at? Anyway, I expect it to be around 3 A, which is way too much power for a toy like this to run continuously as a set piece, not to mention the noise. Stirling engines are usually quite optimised and only require sunlight or temperature difference to get going... Not this one, though. And given the high maintanence (cleaning and manual startup) and power draw, you won’t be running it often. So if you want a piece of steampunk-looking junk to put on a shelf, get some combustion engine parts (which usually only cost as much as the metal is worth, or you can salvage them for free from random wrecks). Or make a freeform-circuit LED or Nixie clock from schematics on DiodeGoneWild’s website (bonus: clocks are actually practical unless you have way too many).

[@gkdresden]

Most of the power goes in the resistance of the wires (or in the current limiter 🤣 ). It is the same as for dynamic speakers. Their efficiency is in the order of 0.5 to 3%. In this case it is even worse because the coil doen't see any back EMF from the magnet. The engine is not driven by the Lorentz force, but by magnetic dipol force. The force between magnetic dipols is very weak.

Lol.. that first "nice" killed me.. ha!

A lot of lubricants contain sulfur. Never use that on aluminium parts; it will ruin them.

[@Peter_Schluss-Mit-Lustig]

How about PTFE (usually sulfur free)?

[@19Edurne]

@@Peter_Schluss-Mit-Lustig Then it should be ok. ;)

[@mernok2001]

Sulfur also reacts with copper. Thats why old rubber insulated copper wires were usually tin coated.

[@19Edurne]

@@mernok2001 Thanks, I didn't know that. I'll go to bed less stupid tonight. :)

[@Z-Ack]

What lubricants contain sulphur? I couldnt name a single one that does but i can name 10 off top my head than for sure dont contain sulphur.. besides why the hell would they put sulphur in any lube as it has no lubricating properties and would only make it smell like farts.. never had a lube that smelled like farts.. maybe garage door lube.. but otherwise any grease, ptfe, white lithium, gear oils, mineral oil, 3 in 1, cutting oil, gel lube, even butt lube all are sulphur free.. and what other lubes would you possibly need for anything?

[@medienmond]

You are exactly just like me, having to ttake everything new and shiny directly apart. Are you sometimes left with your things not coming back together as time goes by, because you were diverted by something else? What a cruel life, but we now know how the thing has worked before it came into our proximity. I have a new sla 3D printer since last week. Yesterday i partly finished disassembly and today i even got a little further, exploration of the included linear rail blocks to clean them and making them runmore smoothly. There are so many little balls inside, just unbelieveable.Tomorrow i have to reassemble the second of two blocks and try not to loose focus on the rest...

Connect the input to the output and you'll have free energy for life.

[@BioOrganicPowerPlant]

You have to have regulated current to each you're creating braking power by supplying current simultaneously to both cylinders

[@Debraj1978]

2 cylinder engine is like a push-pull converter equivalent. The back EMF of one coil of push-pull is equivalent to the compression presssure of the non firing engine.

[@andiback]

Wow Sir you are absolutely right, nice idea! Now there can be seen a way to improve this/these electromagnetic engine/s. As I understand you should be able to solder a diode (freewheeling diode) connected in parallel with each coil, releasing energy accumulated by the coil into a current each time the mechanical contact opens. Compared to a relais the back EMF while magnetic field collapses on turning off moment has no slowing down impact on the working coil anymore.

[@eDoc2020]

@@andiback An antiparallel diode would still slow it down because it will then take time for the coil to de-energize. You would likely need to change the timing for it to run well.

[@andiback]

@@eDoc2020 Thank you for this clear explanation. But this raises another question. How to salvage the stored energy in the coils on turning off moments? The whole electric energy is supposed to be converted into accelaration momentum not slowing down at any point of time. Overall from an electrical together with its mechanical point of view this simple motor kit seems to be not that easy.

[@eDoc2020]

@@andiback If you want to retain the cam switches I believe you could use a bipolar supply where the collapse of one coil's field would recharge the other coil's supply, but I don't think that would help much. The main drawback of this motor comes from the inefficiency of the _magnetic_ circuits. Real motors have ferromagnetic material to form a complete magnetic circuit from the rotor to the stator and back. Here the magnetic field is very weak even when you put a ton of current through the coil so it is very inefficient.

$100, not even using insulated copper wire for lower impedance, and quite crudely built, clever concept though, I wonder if it can be scaled up.

"Lower impedance" at around 20 cycles per second at most? Lol.

Its insulated copper wire, it has a thin enamel or laquer on it. If it was uninsulatyed it would be a short circuit(0 turn coil).

Neat device.

[@NaoPb]

I've seen these before. And I must say, they look really neat! But price wise they are not worth it for me. Considering they are mostly just for show and you can run them only for a short time. I'd say if they can somehow manage to make them cheaper to produce and lower sales prices, then these things would be quite nice. Or find a way to make them run continuously.

[@vaclavtrpisovsky]

I’m afraid you cannot make them auto-start unless you periodically reverse the voltage on each coil... which DC brushed motors solved more than a century ago.

[@Z-Ack]

Nobody said anything about auto start,. Did you reply to the wrong comment or are you just that dyslexic and interpret what youve read as what passed through your head as well.? Kinda like how crazy people talk to themselves..

[@gkdresden]

It would be much more efficient if you would use permanent magnet systems of small bass or broad band loudspeakers using the voice coil as piston. It is only important, that the voice coil can propagate over distances of a few millimeters.

[@BioOrganicPowerPlant]

So you need a device something like a electro operated cam or an or a Electronic coil

It needs an electronic "ignition" via a sensor and MOSFETs

It's a model of an early electric motor, from the 19th century, reminiscent of an engine.

[@drdrums1]

It's basically a linear electric motor, of a sort. But definitely a novelty. Rotating electric motors clearly are superior, as you note - much more efficient, and they deliver smooth continuous power. Like the difference between a piston engine and a turbine engine. Turbines are much simpler, smoother, and tend to be more reliable.
