@@shawnmatheson3492 fuh-huh-huh-huh-UDGE that. Yes, it's very cool, but over five C-notes for a heater fan just because it's cool... that's for people who have more money than sense.
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.
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.
Glad you are back and feeling well enough to be back at making such good quality videos. Was beginning to have withdrawal symptoms while you were on the mend.
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.
I remember seeing a video a long while back of a kid building one out of JB weld and copper tubing, always wanted to build my own for shits and giggles. I think the channel was "MakerJ101" but I could be wrong
@@Mrbfgray Yup, most preachers are so heavenly minded they are no earthly good! This preacher remained humble and provided an external combution engine to help mankind.

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.
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.
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.
I so genuinely love these! Years ago, I purchased one for my grandfather's stove and it took a small wood stove that gently warmed his family room in the basement, turning it into a real furnace that could make the entire basement and 1st floor a warm and tasty paradise after just a few minutes. All from a simple radiator-like device! So neat!
There's something very cathartic about watching a mechanical object run so smoothly and flawlessly. Also I see the watch buying bug seems to have struck again, some sort of Sub with a blue bezel and a Daniel Craig bond nato?
Dual power pistons, can you imagine that? I'm having flashbacks to the alternators. The first thing this brought to mind was the candle heat powered angel ornament. Its beautifully engineered Cody, I'll have to remember this if I ever get a wood stove.
I have always wanted to see someone pair a sterling engine with a pellet stove. The sterling engine would drive the pellet auger removing the need for electricity to keep the stove running.
Brilliant! Now power up the computer with spc control to control the auger. Next figure out how to turn it on an off with a thermostat. You must be a enjineer.
Hey Cody, I just watched another UA-cam video explaining how these engines work. Apparently if it's running on top of a warm stove and then set on a cold surface such as ice, it will slow down, stop, and run in reverse. Just a cool little fact I learned and wanted to share.
I have one of those thermal conductive fans to improve the performance of my Buddy heater. Not as beautiful as this, but amazingly effective. A ton of heat just goes straight up where it is not needed. This helps move the air around a bit for better dispersion, less hot spots.
Yes, we have one for the wood burner it works with a piezoelectric element which creates electric to power the fan when one side is hotter than the other 👍
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.
This video, your ram pump video and your wood stacking (pic-a-roon) video are my favorites so far. Physics and practical farm boy uses of natural science. 👍
Lmao 🤣🤣🤣 thanks for the laugh Cody! I was extremely well versed in Sterling engines and am now much less so! This was great and I hope you know we love you for your self awareness
You are sounding much better Cody. If I remember right, this is the 2nd time you've gotten Covid? Praying you have bulletproof antibodies to protect you from future infections.
I'm glad you sound like you are feeling better. How is everyone else doing? Can you tell us where you got the little fan, please? I'd love to put one on my wood stove. Thanks!
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.
I’ve always been confused by the sterling heat engine. I can’t say I’m less confused but what a cool video anyway. Definitely a great quality device. Thank you Cody for your amazing content. Have a wonderful thanksgiving and a merry Christmas for you Mrs. W, jack and of course the sweet loaf.
@@nicholasmartin5446 Probably not like I should've been. Took me an extra semester before I started understanding what my foreign professor was even saying.
@@nicholasmartin5446 Yep I learned it the hard way. While the first few classes are boring and just the repetition of the old stuff, if you skipped a few classes more it jumps straight to the new stuff you'd never heard about.
I have one of these that runs on the heat given off by a mug of coffee. Beautifully smart but power companies don't really fear them as their output is hardly more than the input energy and barely any torque. Although they're just enough for a simple fan like this, nice explanation though ;)
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. It's a really good example of just how many different machines can be made to do the exact same task on the exact same physical laws, while differing drastically in construction method.
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!
Good to see the Rolex back on the wrist Cody! I guess just like the Benchmade the good old standby always ends up ousting the shiny new toys. I get it though, I'm a creature of habit too. Glad you're doing well and I hope the same for the rest of the family. Missed you while you were gone.
I have a good friend living in the Bull Mountains of Montana who has a wood stove to heat his tiny house build. This fan sure looks like a good solution for our winter weather.
I must say when I first learnt about the sterling engine, it was hard to understand because they used the beta type sterling engine which was the simplified version of the alpha type sterling engine. Many components of the alpha type engine have been combined to make the engine more compact in the beta type design which makes the explainations harder to understand.
Now all you have to do is make some copper coils or magnets strategically placed and then you can start storing some of its kinetic energy into a battery bank or charge your phone. I guess if you made a big enough one you could power a house. Idk it looks beautiful and is masterfully built. I’m glad I ran across this.
I got my little brother a engin like this that you put on top of your coffee cup and when the motor stops the coffee is just the right temp :-) thank you Cody you have a beautiful piece
It’s refreshing to see a person who is not afraid to stumble in the public eye….your videos are brilliant common sense, which is a breathe of fresh air today in a world of senseless dominance. Thank you.
Hahahah! I notice all of the East Coast Heating Guys chiming-in. LOL!! Y'all are the "original" Steam Reamers. The very first, "Old Dead Guys" reside "over there". Respect!!
There is a huge Stirling Engine near me that generates power. It has a 30 ft reflector dish made of multiple plates the engine is mounted on the center arm and runs off heat of the sun. Pretty cool, looks like a huge flower.
I’ve been trying to figure out how to use stirling motion for alternative energy for years. This gave me an idea of how to use my spring fed ram pump and a stirling fan to cool my wood shop here in the south.
That is the most neatest thing I've ever seen in a long time and the thing about it is that it also makes it a great tool into explaining how and internal combustion engine works for those that have no idea Cheers Anthony
My father was so proud when he finally got his Barometric CLOCK. Fine wood, brass and glass construction. Self running ( perpetual motion) has a wedge arm under case to stop it. I'm sure that you can find one some where still.
The only cycle more efficient then the Stirling cycle is the Carnot cycle but the Carnot cycle is theoretical; Stirling cycle is actual. Not only what you have is a beautiful piece of art, but it's completely functional too. Not often do you see both at the same time. Cool stuff, Cody. :)
That is a beautiful Sterling motor. They work off of hot and cold. They can be hours of entertainment. For no animation you did a pretty good job of explaining how it works👍
Very excited to use my new tipi tent with wood stove this weekend. I’d imagine that a stove fan may even help warm the tent. Perhaps I’ll give it a shot. I’ve been fascinated with those fans for a while, anyway. Great vid! Thanks & it’s great to see you doing well.
I use a fan in my hot tent, it definitely does help. Most stove fans are a Peltier circuit (generating an electric current from the difference in temperature between the top and bottom of the fan), but I imagine a Sterling engine would work as well, if you could find one small and cheap enough to justify packing on a camping trip
@@LightfeatherxX Thanks for the input. It may be cheating but I already found out how beneficial a cot is to sleep on. Just being slightly elevated makes me so much warmer, even though the ground is ultimately fine. I’ll give the fan a shot, though. Just purchased a new mattress and also plan on getting new tires for my vehicle but once I have those taken care of I’ll have some more spare cash and do research. I appreciate the info!
@@prepperpov5852 No worries! Yea, a good cot can definitely make the difference between a cold sleep and a nice comfortable sleep. One point of note, how useful a stovetop fan is in your tipi depends on how big the tipi is, and the height of the peak. A 4-8 man tent will benefit more from the forced flow of air then say a 2-3 man. It's main benefit is keeping the hot air from stagnating at the top of the tent, but (for me at least) it does make a noticeable difference to the warmth felt near the ground in my tent
I have something similar. A small electric motor and a thermal pad that turns heat in to electricity. It was left with the house. I was in the hard ware store and saw the same thing, next size up version......$200. I passed on adding a second one for now.
It gives me the fizz! And loving the nato strap just like the royal navy used to issue with it milsub rolex submariners it used to issue to navy divers through the 60s and 70s, nice 👍
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.
Awesome, this is classic dad'splaining. Super neat device. I know mechanisms like this continue to be invented today in the pursuit of energy conservation. A symbol of the industrial revolution.
Cody I could see myself setting by the fireplace in my wooden rocking chair with that miniature Stering gadget with what looks like a tiny helicopter blades keeping me warm through the winter months. 👍
I showed this video to the CEO of our local power company and he had a seizure. The fear was overwhelming. We had to take him to the hospital, it took the doctors almost an hour to get him to stop laughing............
I'm in trouble now! Went to their website and almost bought their Skeleton Wood Stove Thermometer and stopped............because I don't have a woodstove at the moment.
A site called TNT with Robert Murray-Smith is a physics teacher, and he uses the Sterling engine often. He is easy to understand and entertaining. A lot of his videos are energy related.
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...

This is the accuracy you get with the metric system Cody!!!!! Glad you’re feeling better. Andrew (UK!)
This is the type of content I have missed from this channel
I must say when I first learnt about the sterling engine, it was hard to understand because they used the beta type sterling engine which was the simplified version of the alpha type sterling engine. Many components of the alpha type engine have been combined to make the engine more compact in the beta type design which makes the explainations harder to understand.
Now all you have to do is make some copper coils or magnets strategically placed and then you can start storing some of its kinetic energy into a battery bank or charge your phone. I guess if you made a big enough one you could power a house. Idk it looks beautiful and is masterfully built. I’m glad I ran across this.
I got my little brother a engin like this that you put on top of your coffee cup and when the motor stops the coffee is just the right temp :-) thank you Cody you have a beautiful piece
It’s refreshing to see a person who is not afraid to stumble in the public eye….your videos are brilliant common sense, which is a breathe of fresh air today in a world of senseless dominance. Thank you.
This fan and the ram pump both amaze me. So cool.
Natural laws of thermodynamics. You did a great job, thanks for the younger people, yes .
Hahahah! I notice all of the East Coast Heating Guys chiming-in. LOL!! Y'all are the "original" Steam Reamers. The very first, "Old Dead Guys" reside "over there". Respect!!
That is the coolest stove topper I've seen. Glad you are feeling better. My taste and smell are still weak from CV19 that I got around Easter.
There is a huge Stirling Engine near me that generates power. It has a 30 ft reflector dish made of multiple plates the engine is mounted on the center arm and runs off heat of the sun. Pretty cool, looks like a huge flower.
Seriously, you explained it well and I understand how it works! Thank you for showing it to us!
That's a very cool little engine. I'm an engineer so things like that always fascinate me.
I understood your explanation of how those fans work. I was just talking about them yesterday and we wondered how it works. Now I know.
Glad you’re back and still e joying sharing your love for cool stuff like this.
I’ve been trying to figure out how to use stirling motion for alternative energy for years. This gave me an idea of how to use my spring fed ram pump and a stirling fan to cool my wood shop here in the south.
NEED
And all it needs is a gaurd to protect clumsy fingers
That is the most neatest thing I've ever seen in a long time and the thing about it is that it also makes it a great tool into explaining how and internal combustion engine works for those that have no idea
Cheers Anthony
I’ll have to be on the lookout for one of those!
My father was so proud when he finally got his Barometric CLOCK. Fine wood, brass and glass construction. Self running ( perpetual motion) has a wedge arm under case to stop it. I'm sure that you can find one some where still.
I like how you paired the two tone stainless steel Rolex with the Warpfive with brass and stainless steel.
Thank you Cody for sharing such magnificent equipment on the channel. I might just have to put this on Santa's list!
The only cycle more efficient then the Stirling cycle is the Carnot cycle but the Carnot cycle is theoretical; Stirling cycle is actual. Not only what you have is a beautiful piece of art, but it's completely functional too. Not often do you see both at the same time. Cool stuff, Cody. :)
That is a beautiful Sterling motor. They work off of hot and cold. They can be hours of entertainment. For no animation you did a pretty good job of explaining how it works👍
Glad to see you’re feeling better Cody!!
Very excited to use my new tipi tent with wood stove this weekend. I’d imagine that a stove fan may even help warm the tent. Perhaps I’ll give it a shot. I’ve been fascinated with those fans for a while, anyway. Great vid! Thanks & it’s great to see you doing well.
I use a fan in my hot tent, it definitely does help. Most stove fans are a Peltier circuit (generating an electric current from the difference in temperature between the top and bottom of the fan), but I imagine a Sterling engine would work as well, if you could find one small and cheap enough to justify packing on a camping trip
@@LightfeatherxX Thanks for the input. It may be cheating but I already found out how beneficial a cot is to sleep on. Just being slightly elevated makes me so much warmer, even though the ground is ultimately fine. I’ll give the fan a shot, though. Just purchased a new mattress and also plan on getting new tires for my vehicle but once I have those taken care of I’ll have some more spare cash and do research. I appreciate the info!
@@prepperpov5852 No worries! Yea, a good cot can definitely make the difference between a cold sleep and a nice comfortable sleep. One point of note, how useful a stovetop fan is in your tipi depends on how big the tipi is, and the height of the peak. A 4-8 man tent will benefit more from the forced flow of air then say a 2-3 man. It's main benefit is keeping the hot air from stagnating at the top of the tent, but (for me at least) it does make a noticeable difference to the warmth felt near the ground in my tent
I'd love to buy one of those just to look at but the electric generator versions work so much better And start spinning on their own When they're hot
I have something similar. A small electric motor and a thermal pad that turns heat in to electricity. It was left with the house. I was in the hard ware store and saw the same thing, next size up version......$200. I passed on adding a second one for now.
Super cool engine! If I ever get another wood stove (or coal) I would get one to put on top. What a great idea!
This is how I end up describing everything, I love it
Been using one of those for the last couple years .after seeing this now I want to build one so I can see the internals. That's awesome
It gives me the fizz! And loving the nato strap just like the royal navy used to issue with it milsub rolex submariners it used to issue to navy divers through the 60s and 70s, nice 👍
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.
Awesome, this is classic dad'splaining. Super neat device. I know mechanisms like this continue to be invented today in the pursuit of energy conservation. A symbol of the industrial revolution.
Cody I could see myself setting by the fireplace in my wooden rocking chair with that miniature Stering gadget with what looks like a tiny helicopter blades keeping me warm through the winter months. 👍
Wood stoves in general are under appreciated
Glad to see that you seem better!
I'm glad to see you're feeling better
I showed this video to the CEO of our local power company and he had a seizure. The fear was overwhelming. We had to take him to the hospital, it took the doctors almost an hour to get him to stop laughing............
I have seen similar items in the past on woodstoves, nothing quite this beautiful though. Thanks for sharing, now I want one. Ha ha
I'm in trouble now! Went to their website and almost bought their Skeleton Wood Stove Thermometer and stopped............because I don't have a woodstove at the moment.
Somewhere a engineer is screaming at you .. LOL
I had suggested the stove fans a while back and you told me it was a gimmick glad you finally tried one out
A site called TNT with Robert Murray-Smith is a physics teacher, and he uses the Sterling engine often. He is easy to understand and entertaining. A lot of his videos are energy related.
this is probably the best application for a Sterling engine
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...
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.
