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.

[@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.

[@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.

[@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.

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.

Yeah, I saw that and got sticker shock, myself. But it IS a "free-wheeling" machine. Costs nothing to run it and it DOES look really cool. Yeah, that's the "issue" with these "expensive" heating (i.e. solar, radiant, in-floor, etc.) and cooling systems is the initial costs. AFTER that (getting OVER the initial shock) though, one comes to find that over time, it starts to pay for itself... 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.

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.

[@ka9dgx]

Cody, you sound better, I hope you have a quick and full recovery. The thing to know is that all the engine is a closed system. The air is moved between the top half and the bottom half by the displacer. When the displacer is at the top, the air inside the chamber gets hot, being near the stove, and expands. It slips past the displacer, and pushes the two pistons on the top upward... which then moves the fan, and the displacer moves towards the bottom. Now the air is in the top of the chamber, which is much cooler, and it shrinks. This allows the pistons to move downward, moving the displacer... and the cycle repeats in low pressure, quiet awesomeness. The Stirling engine was invented by a Priest who was upset at all the deaths caused by high pressure steam explosions. There are no large pressures in a Stirling engine. That is a beautiful piece of technology. Thanks for sharing.

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

[@brianbaird6528]

This is how the Stirling Cycle works in this engine. The displacer is used to move air up and down in the chamber. When the displacer is pulled up, the air goes beside it into the bottom of the chamber, where the heat is. This makes the air expand, pushing the pistons up and producing power. Part of this power is used to lower the displacer, forcing air up to the top of the chamber, where it is (relatively) cool. This causes the air to contract, sucking the pistons back down and producing power. Some of this power is used to again raise the displacer, forcing the air down where the heat is, expanding it and causing pressure that pushes the pistons up, and the cycle just keeps repeating.

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. :-)

Nowadays they make also electrical fans for the woodstove that use the difference of heat to create electricity, which powers a small motor.

[@Johnny-dp5mu]

Energy from the stove is being consumed by heating the devise hence spinning the fan. It's not free energy. The fan moves warmed heat from near the stove away bringing in cooler air which warms and is blown away. Might consider a section drawing to help better understanding Your fan is indeed a masterpiece.

Doesn't say free energy. But I would day that no power company is concerned about it. I'll also say for the price you could run a fan for a long time for much cheaper.

[@Johnny-dp5mu]

@@nickgamble4544 agree, Bet cost was in the hundreds $$$

Wow I didn’t know it was possible to fall in love with an object. Cody I’m not talking about you I’m talking about me! 😂

[@foundationrepairbear]

I've been fascinated by these for years now! Keep up the great videos man much love prayers and respect from Tennessee!

[@dandan1364]

Glad you’re back and still e joying sharing your love for cool stuff like this.

[@yukonheart]

200 years old - nothing power companies fear - cant generate enough power to run much of anything

[@comfortablynumb9342]

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.

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.

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 survived two semesters of engineering thermodynamics and have no idea what you just said.... Ha. I don't know how it works either. Looks like a great product to distribute heat around the building. Some guys tried to make a stirling engine in the machine shop and I don't recall them working. The company should include a one page laminated description of how it works in layman''s terms so when you have guests that are curious you can readily explain it.

Does this push more air than the ones with just the heat fins? They need to make one like this with a little charger to help charge off grid battery.

NASA made a stirling engine and put it in a truck. It could take any fuel. I’m trying to build one to run a water pump to filter a small pond. Stirling engines are amazing.

[@hammerdownfabrication]

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

[@fudogwhisperer3590]

You should check out a free energy device called a Trompe. They used them to supply compressed air in the mining industry. Compressed air can drive anything.

[@DakotaBiker01]

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.

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. 👍
