Funny story. My father was so proud to have installed a wood stove in his old house that he purchased one of these engine-type fans for on top of it. He purchased a premium model and claimed that it made the stove look more sophisticated. He was disappointed when the brand new, rather expensive, fan did not spin but for about 5 rpm. He left it sit on the stove as a decoration though. One day I walk past it and pick it up to examine the mechanics of it. I happened to notice that there was a cellophane cover (like what comes on a new TV) on the very bottom between the fan and the stove. He removed that cover, and within 5 minutes the fan was blowing clear across the room with warm air.

Reminds of my situation. Bought a house from my now neighbors (they subdivided and built new). When they did the kitchen remodel 20+ years ago, they put a built-in AC to cool it (there was no central AC). He loved it, but his wife thought it was way too loud and refused to use it. Come about 3 years after we buy, and we put in central AC on the first floor, so we remove the AC. First thing I see is a “Remove shipping strap before installing and operating”… on the shipping strap that is still installed. Gave it away, and it was very silent apparently.

[@bluebutterflywellness2273]

Looks great! Just bought a similar one but unfortunatrely i have a recessed built in stove that leaves no surface area for fan to sit. Therefore it would be awesone to have a manufacturer create a modifed version to allow for vertical adhesion with perpendicularly positioned blades to allow the same function in this instance.

Cody, the Sterling engine was invented by a preacher. He was concerned about steam boiler explosions and he designed an engine that used air instead. Those are graphite pistons and glass cylinders for low friction.

[@edlibey8177]

Love you videos. Your description is fairly accurate except: I think the displacer is made of a light non metallic substance. The temperature difference does tend to allow the heated air to rise but, that is a tiny effect countered by the displacer. The real motive force is the heat increasing the pressure inside the lower cylinder. I am a retired chemist. Worked in an industrial lab but, as part of a local science outreach program, I used my sterling engine to teach gas laws to middle school students. Basically, heating a gas in a closed vessel increases the pressure. That pressure pushes the top pistons. As the gas expands in the top pistons it cools and is pushed back down into the hotter lower cylinder by the return motion of the piston and the displacer. For what is worth, I included a poorly written but, more detailed description of the physical chemistry of the system below. I believe I was a good scientist but, never a very good writer so for what it’s worth…. Ideal gas law is PV = NRT. P is pressure, V is Volume, N is the amount of gas, R is a constant to keep the mathematical terms all the same, and T is temperature. Seems complicated except the amount of gas (in this case air) in the system remains constant, the gas constant is also constant. So simplifying the Pressure and the volume varies directly as a function of the temperature. In the big cylinder where the gas is heated the volume is also constant. So heating the gas increases the pressure or mathematically since V, N,R are all constant then P=T. The pressure increases in dirrect proportion the temperature change. If the lower cylinder was sealed that is all that would happen. The increased temperature would just cause the gas pressure to increase. However, the bottom cylinder isn’t sealed but, is connected to the upper cylinders. The increased pressure in the bottom cylinder pushes the pistons in the upper cylinders. In the top cylinders the pressure pushes the piston. As the piston move upward the volume of the cylinder increases allowing the gas to expand. As a gas expands it cools and further cooling occurs because the upper cylinders are further from the heat source. The purpose of the displacer is to help move the cooler air at the top of the piston back down to the the bottom of the bottom piston. Why a gas cools when it expands is a longer and for me a much more difficult explanation. But, most refrigeration is based on the fact that gases cool when they expand so please take my word for this. Again love your videos so keep them coming.

[@100GTAGUY]

Yeah trying to explain how hot expanding gas eventually cools itself does get a bit complicated and convoluted without a full on lecture plan lol Without getting into Boyles law, bernoullis principle, and the other laws of thermodynamics you cant say much to anyone. Trying to explain how they used 600+ degree air to cool jet engines down is even more fun haha, all the while the compressor is simultaneously heating and cooling intake air via compression, expansion, and airflow manipulation using bernoullis principle and multiple airfoil designs to fuether control temperature and density.

[@zogthehog]

That is an awesome gadget! I also wanted to say I am sorry for the loss of your father Cody, I have been a fan of your channel for a long time and I really felt for you when you posted about it. After that video it compelled me to patch things up with my Dad, him and I hadn't been speaking for a while, but I didn't want to waste any more time not being in touch with him. We have to make the best of the time we have with the ones we love before its too late. Glad to see it seems like you're doing a bit better. Cheers from Ohio!

[@cartertrefz4585]

A Sterling engine has two strokes. Stroke one is When the displacer is lifted the air rushes down towards the hotplate and expands, driving the pistons up. The second stroke is when the displacer moves down and displaces the air upwards allowing it to cool, contract, and suck the Pistons down.

If you're using this with a Catalytic stove instead of a standard one, put 3 spacer washers under it in a triangle pattern to create an air-gap. Two at the front near the blade, and one at the back in-line with the crankshaft. Not doing so can damage the engine, oh, and oil/clean it twice as often. I learned that the hard way.

[@jamesbuildwise9141]

The displacer is used to cause the temperature differential (the displacer is likely made of a heat insulator) when it's at the down position (closest to the base) it blocks the heat and the air inside the chamber starts to cool causing the pressure to drop. Which in turn allows the power piston to move down. At that point the displacer is now in the top position and isn't blocking the heat, exposing the air to the hot side. This increases the pressure and causes the power pistons to move up and then it repeats. The air doesn't push the displacer up or down it's just a very loose fitting piston to displace the air from the hot side to the cold side, to cause the air to expand and shrink.

[@lynnleiby]

hahahaha!!! reminds me of a conversation I have often with customers. I own a window cleaning business. Thermopane windows have 2 layers of glass with, in theory, a vacuum seal between. When the seal is compromised, moisture can get in between the glass layers and cause a foggy appearance in the glass. Window replacement companies claim it's "energy efficient" for you to replace your windows when that happens. Customers often ask me if they'd actually save $$ by replacing the windows. Sure you'll save energy. But you'll spend $20k on new windows. At what point will you begin to enjoy the return on investment? In the 20 yrs it will take you to break even, all your window seals will be blown again. :-)

Another really cool thing about Stirling engines is that there's so many differrent designs of them all working off of the exact same basic principal.

But remember... this thing takes NO energy (other than what you are already using) to run. So, in TIME, it will literally pay for itself. IF one has an area that is not "heating" (heat transfer is too great elsewhere) this will help "push" the heated air over in that direction. In that case, eventually, it will pay for itself. Heh!

IDK... this just pushes air... but if one has a "corner" where the heat transfer is just not that great, it may get up to ~5-10 degrees"-" cooler than the rest of the domicile.

The stirling engines have one problem that tends to limit their utility, they need abundant cooling. 🤔 That said, driving a fan on a wood stove is essentially the ideal application. As for your explanation of the mechanics. I’ve studied the engines for a few decades. You did ok, the individual parts actually aren’t so bad in terms of complexity. The thing is, they work in tandem with other parts and there’s a number of interactions that get 😳. I actually think there’s some real potential for advancement, I would however be pretty hard pressed to pick them out and to then explain them.

One air reservoir. When displacer is up, the bulk of the air is on the hot side and expands. Expansion pushes power.pistons up turning the shaft 1/2 turn. Shaft moves the displacer down pushing the reservoir air to the cool side where it contracts as it cools. This pulls pistons down turning shaft 1/2 turn. Repeats as long as ther is a hot side to expand the air and a cool side to cool it.

Love the video. Glad to see you doing better. I vote for more Mamma Kitty in videos. More pets in general. Not a lot, just some. Thanks for the content. God Bless You.

Beautiful engineering from the British.

Good to see you back on your feet and in high spirits!

I have a 1/4 scale Ryder Ericsson I put together from casting many years ago. A late friend of mine had a full size version.

Sterling Engines are one of the best examples of how all work is done by things humans make. We find a concentration of energy, heat, chemical energy like gasoline, atomic energy like refined uranium, and then as that energy does what energy does and disperses, we ride that wave

This fan and the ram pump both amaze me. So cool.

I have seen these as a "Children's" STEM Project/Kit. (Science, Technology, Engineering and Math) But I usually see them with a Safety Fan Grill. Great for distribution of Heat in a Large Area, and really cool to watch!

Like an alternator, why have one power piston when you can have two?

[@RussellWiegand]

Somewhere in the mountain of old papers downstairs is a set of mimeographed instructions for a DIY sterling engine. Makes me wonder if I could build one and mount a fan.

[@SamOHalloran]

I built one of these in Highschool metal fab class, machined it all myself. Very cool and simple motor. Never though about putting it on my woodstove...

Great to see a 100+ year old technology that works perfectly till this day . To bad they don't teach this in schools...

[@jojoba35]

I use a similar fan on my stove in the hot tent. Makes all the difference in there!

See also the Ecofan by Caframo, I've known many ppl owing them for decades. I'm not familiar with the differences in operating principle compared to a Sterling engine (if any), but the net effect is identical if the only work you are trying to achieve is to recirculate air in your stove room.
