Mini Stirling Engine - MAX RPM (Blow-Up Attempt #1)
Вставка
- Опубліковано 15 вер 2024
- In this episode, I push this little mini Stirling engine to the extreme and run it as fast as it can possibly go by applying as much heat as possible to the hot side of the engine.
After achieving a whopping 4,000 RPM, I then proceeded to dismantle and take apart the entire engine so we can look at the parts and how it's built and how it's made.
I was very impressed with the build quality and the overall functionality of this mini engine, I haven't seen anything better than this mini Stirling engine for the price.
For this reason, I included a link to buy this engine below, as well as a discount code so you can save even more money.

Warped Perception on the website it says it runs at 1700-2000 rpm. I assume that is incorrect.
Do they ship internationally? Can't find anything on their site
Do they sell rebuild kits? ;0) maybe have some titanium parts made by ToT and AvE. Heh
Warped Perception , that was fantastic , my little engine similar to yours , that is some outrageous RPM's , enjoyed the slow motion circle around from above ,
on your Briggs engine , use a regular cylinder head , cut out the center and use a piece of Pyrex glass or oven tempered glass for the seeing inside the engine
Warped Perception 8:37 the engine did survive the first test. It was still operational.
Since it works with temperature variance, hit the other side of the heat exchanger with liquid nitrogen and you should get faster RPMs.
Funny, that's one of the first things I thought of. I may try that in the future
@@WarpedYT yes!
@@WarpedYT Or it might shrink the cylinder and lock it up. Only one way to find out.
@@grants169 Or crack if theres big temperature difference. Like hundreds of degrees.
Also fill the cylinders with helium, it will run faster
I'm thinking of Stirling Engine swapping my Ferrari, then hiring someone to hold a torch to it whenever I want to drive. It would surely be cheaper than maintaining its current engine.
Samcrac
Sounds like sam,s on crack ....
😂😂😂😂😂
Well I bet you that I would be able to build you a large version of this engine, if you really wanted to put it in a car... Instead of a turbo exhaust pipe sticking out of the hood, it would be a giant roofing torch with a 3 foot blue flame!!! That may be a really cool project can you imagine!!
Great idea for a future video.... large scale it baby
@@WarpedYT Time to contact Garage 54
I think you spelled Stanley Steamer wrong
1:26 No, this isn't a miniature version of a Stirling engine, this IS a Stirling engine.
No, it is a Stirling version of a miniature engine.
Lol I wanted to make this comment. Thank you
@Craig Roop Not all Stirling engines have a regenerator.
@@Jupiter__001_ technically they should have one to be a Stirling engine not a hot air engine. stirling engines are what Robert stirling called his version of a improved hot air engine. One major improvement was that it included a regenerator.
@@kraklakvakve no, it is a stirling miniature of a engine version
The generator is creating drag, you should remove the belt to get even higher RPMs.
Yes
Why tho, this is a toy, not that efficiency matters
Well being that the generator wasnt connected to anything, and wasnt shorted, the only resistance is the slight amount from the bearings in the generator itself, and mechanical losses due to heat
if overheat is issue then just submerge it in liquid nitro!!10k rpm confirmed
@@KitKitChanIsaac yes! Nitro=sp33d
You can put ice on intercooler and maybe runs at 5000 rpm
I have a stirling engine and tried to do this myself... then realized I’d be sad if it broke and stopped lol.
I love your slow-mo shots, they're so cinematic compared to other channels!
Thank you, and TBH I haven't even done anything nuts yet, I've done a lot of cinematography, camera work, and high speed filming for many big movies, coming up soon I'm going to do a whole series recreating techniques I have used for big movies, I'm going to do them as individual episodes here on this channel.
@@WarpedYT That sounds very interesting! I'm looking forward to it.
Warped Perception Keep it up, these shots were amazing!
@@WarpedYT what music was used during that slo-mo sequence?
Wow! I'll bet the company that makes those never envisioned THAT test! In your high speed footage it wasn't even flexing anywhere that I could see. The smaller a thing is the stronger it becomes but that was way beyond it's design I am sure.
Oh, very interesting engine! Beautiful slow motion!
Thank you !
Beautiful slow motion indeed !
"Engage safety squints" -AvE
Lol... For sure !
He makes merchandise that's a hard plaque you can put on your toolbox and/or in shot!
IT'S CLEETUUUUUUSS lol
Skookum!
Technically, this engine was designed with safety in mind. If I'm not mistaken, Robert Stirling made this to avoid locomotives from exploding because of extreme heat
Put that thing in a rc car see if it'll push it along! Great video!
Awesome idea !!!
These things are all HP and no Torque
@@michaelesposito2629 That's why you gear it down. There is no such thing as "all HP and no torque", because without any torque, there is no horsepower. Horsepower is just the engine torque multiplied by the rotational speed, then divided by a constant. This engine would likely be able to power a small RC car, it would just have to be geared down to convert some of the rotational speed into torque.
Go further, get a big sterling & put it on a go cart!
Funny, I am familiar with these engines, and from watching other videos you put out, I said that YOU would probably get 4000 rpm (which is amazing). To apply cold on the other piston, a super easy method is to use electronic duster. Pleas hook a volt meter up to this. Also a solid metal design would be able to take a lot more punishment. Using heat, and cold with a metal design, YOU may get 6k or 7k rpm. Be fun to watch!
Awesome!. Electronic Duster?
@@WarpedYT multi purpose compressed gas cleaner. Can be found at walmart in electronics. When sprayed it becomes super cold and if sprayed while holding upside down a liquid comes out and is super cold. Can cause frostbite. Its cheap, readily found and probably one of the easiest ways to get the Stirling piston cold quickly.
OR - configure a small fan to the output wheel crank and aim it at the cold cylinder. Maybe it’ll feed itself to some degree
Mine going a lot slower got about 7 volts last I remember, at the rpm his is making, maybe like 10 to 12 volts. I'm not really sure how that whole thing works though
That piston looks like someone got ahold the big nitrous jets.
That's the same thing I thought when I first saw it !
I’m actually extremely impressed! I have a new found respect for sterling engines, thanks! If that piston and cylinder we’re stainless you could really work this engine
What a lovely, robust little Stirling!
I'm guessing that the hot cylinder is borosilicate (Pyrex), the hot piston soda-lime glass.
That she spun that long under those conditions is truly remarkable.
Very good production of a cool vid.
The "Glass tubes" are actually quartz. I clicked the link,the engine is only 70 bucks!
The way the light was rotating and the aura from the heat sent me back into an lsd flashback. The way it looked reminded me of visuals while tripping. Still love this video
Seriously just thinking the same, looks so similar to me.
Nice! Order confirmed! Great deal even without the black friday discount code! Thanks!!!
for the heat, can you put a magnifying glass to harness the sun, then on the other end generate electricity. Just for fun.
Yes you can any type of heat will make this sterling engine run.
It’s been done.
Oh thats how solarpanels work! multiple mini Sterlings with generators
@@vattenpoken368 you're kidding right?
No that sounds pretty true i thought
Just shows you how much of a difference a well balanced engine makes
Even with how many moving parts there are, it revved to 4000! Damn. Some old engines could never dream of that haha
Make the crank smaller, get the generator off with the belt and make the cold side touch liquid nitrogen.
Hello sir, I am vidit vadhera from India , I regularly watch your videos and your perception is just so clear about engines and their working, about Stirling engine you can also try and focus the sunlight from a big lense and see that if the engine works from a renewable heat source.. thanks , take care!! 😀
That's a really neat sterling kit. I ordered one for my brother!
Thank you, make sure you use the discount code!!
I have one of these i made during college for some cnc/machining courses, these engines are really cool theres so many ways that you can make them to absorb heat even from your hand to power
The reason Stirling engines are not in our cars today is because they invented the internal combustion engine. Which had faster startup and better throttle response. NASA actually did make one that fixed these problems, but the cost per engine was very high because of the use of exotic materials. On the other hand some military submarines use these engines , and they are said to be much quieter than a nuclear powered. sub. Only down side is they would need more frequent refueling compared to the nuclear fuels rods lasting many years. But would be much safer with out all the radiation.
Uh couldn't you just power these with nuclear heat? Like a more efficient RTG?
@@virtualtools_3021 You can power a Stirling Engine with any heat source. You can even run it with extreme cold . The main goal is to have a temperature difference between the two cylinders.
@@FalconWing1813 yeah, uranium rods for the heat so it won't need refueling and seawater for the cold side
@@virtualtools_3021 True that could be done for sure. On the flip side the Swedish Gotland class submarines actually use hydrogen and oxygen to provide heat to the Stirling engine. This combo of Hydrogen and Stirling engine, has made the Gotland class one of the quietest submarines in the world. Its much simpler and less complex than nuclear. I would like to see alot more submarines with this tech to reduce nuclear waste. And save tax payer money.
@@FalconWing1813 i don't see how the hydrogen and oxygen could possibly be quieter than a rod of uranium, but i do see how it could save money and reduce waste
Nice job, I like the content! And you hit 500k subscribers, congrats!!
Thank you ! .. yeah I just haven't posted any videos but I'm back on the UA-cam stuff now
Ooh! Ooh! Ooh! It's THE LITTLE ENGINE THAT COULD! ♥
1:14 my eyes bugged
This one's really good , the rotating and reciprocating masses are so well balanced here in this engine , surprised to see so less vibrations
I'm giving her all she's got!
I wonder if you could water cool the heat sink and make some steal pistons and cylinders to better handle the heat because of better heat transfer. But then again that may prevent it from running, perhaps ceramic piston and cylinder? I really liked that you pulled it apart on video though that was cool, thanks for the video, it has me thinking now lol
replacing the pistons and cylinders with steel would work just fine. Water cooling does in fact improve the sterling quite a bit (as they work on temperature difference, not just heat)
I have this exact same model from sunny tech I ordered on amazon for 95$ and its so well balanced compared to the rest of my collection, it runs great
You should try to make or get a metal piston and cylinder so it won’t melt and you can hit it with an icy acetylene torch!
The acetylene torch was going to be my third test in this episode, but since it didn't make it through the first well you saw what happened...lol
They sell ones with metal already.
Slo-mo walkaround of the running motor looked pretty cool... loves me some reciprocating motion.
The slow motion pan at 3:15 was a thing of beauty
A perfect example of the wonders of simplicity. May not be as powerful or versatile or useful as more sophisticated machines of today, but nothing beats the durability and longevity of simplicity.
3:08 I sat there a realized wow we created this!
Such a slowmo footage, huh!!! 👍🏻👍🏻👍🏻
So do love to see majority of your ones!
Phuckin delicious am telling you
Just a little FYI. In early 2008, true MAPP gas production ended in North America when production was discontinued at the only remaining plant in North America that still manufactured it. However, many current products labeled "MAPP" are, in fact, MAPP substitutes. These versions are composed almost entirely of propylene with minuscule impurities of propane (
This is great stuff. Back in the 50's I always wanted a mini steam engine. I've seen these as well. Good stuff!
JOHNNY Q90 has multiple videos on sterling engines . Great video Mat
I, and a couple other folks, have wondered about power output. It's real easy to get some results with the built-in dyno. Just wire up that belt-drive "motor" with a proper-sized resistor and measure the current. Volts, Amps, Watts!...use an electric model plane Wattmeter that reads out all three. One horsepower equals 745 Watts...use Watts for bigger-looking numbers!
One could even set up another brushed motor running off that onboard generator with a fan to move air through an air/water intercooler that would pull heat off the "cold side" of the motor and make for a higher temperature differential. Make sure that the water in the intercooler thermo-siphons like a Ford Model T cooling system so no pump is needed...put the intercooler higher than the heat source with no dips in the lines. Use model plane silicone fuel line for water lines to intercooler.
I like the liquid Nitrogen idea also.
You could do "dyno runs" stock, stock with intercooling, and stock with nitrogen cooling. THEN you could do runs stock with MAPP gas. Mapp gas with intercooling, and finally MAPP gas with Nitrogen cooling. Maybe reverse the order of the MAPP gas runs so that the damage to hot side happens on the last run. (stock) For stock runs, just pinch off water flow to intercooler.
Compare Wattage on all runs for a full test set!
What he sees during max rpm run: 👌🏻 What we see: Engine.EXE has stoped working
holy carp that slow mo shot was amazing SHOW IT EARLIER IN THE VID i was just about to leave the vid
Man, I don't know if you just mounted your camera on the ceiling fan or what but that shot looks amazing!
I wonder if you could get more RPM by cooling the other side and how much voltage and amps could you get at those speeds!
Imagine how much power that generator produces with the engine going that fast...
I have a suggestion for you brother. Use light gases like Hydrogen or Helium as operation gas and keep it under high pressure to maximize the power output and efficiency of Stirling Engines. You can take a look at Cody's Lab for a video on that topic
I believe that the upper piston was actually graphite with a steel fitting inside. Low friction, doesn't ever melt (it sublimes), easy to machine and soft enough to get along with brittle glass.
That little engine is a champion
Amazing. Simple, easy, without complicated maintenance, no lubricant (aparently). This engine can be used for generate electricity at big scale, of course .
Dude, you have one of the coolest Channels I've ever come across!
Stirling engine is surely satisfying to watch.... I have no idea why??!!!
4k RPM noises sound powerful!
A full size can run a water pump with wood and fire! This is a great motor! Never seen one before!! Old people must have used this on farms!!!
Stirling engines i would say are maybe the future. I have one of the piston on each side like a gas engine. That thing, after sitting for maybe a year, ran. I love Stirling engines.
The model is a real work of art.
Side note - one of the reasons this type of engine didn’t make it is difficulty in controlling speed and throttle. Takes a while to get going. Not good for a car. Maybe more suitable for a home generator or similar. It’s kind of like a flywheel in that regard.
I'm sold ,!
Great vid , totally thank you so much.
☘️
That "conversion into rotational energy" part he just blew by was the main part. Long story short, it's pressure change as air is heated and cooled and temperature change as trapped gas expands and contracts working in unison.
If you increase the temp difference like putting a ice cube or something to cool off the piston/heatsink make it faster? Happy Thanksgiving btw
Yep! some of the low temperature ones can work with nothing but room temp and an ice cube.
shoulda added some thermal mass to the cold side. its all about heat differential, not just heat. hitting it with the torch just heat soaks the whole thing.. gotta keep the cold side cold while you're doing it if that makes sense
Yes I didn't pack think about this, and for my second portion of his video I wanted to cooling heatsink and use an even hotter torch to make it more dramatic. Problem is it didn't make it through my first test.
It'd be interesting to see if this could be run using sun power, focused through a magnifying lens to create the needed heat. Make the whole configuration reposition-able to allow for the earths rotation so it always has the sun rays focused through the lens. Could this be the next 'green' energy source of the future?
Exactly
the amount of EFFORT it took to break this bad boy
I want to see you put one of these and a torch into a radio controlled car or truck. That would be an awesome project. I bet the views would be through the roof.
Love it man! Good stuff! Would love to watch them machine and assemble these engines.
Thank you, I agree !
With that much heat input there needs to be an appropriate amount of cooling added to the "cold" side: Forced-air + extra fins or a water-jacket and radiator? The higher the temperature differential the more work that can be extracted = higher RPM. Great vids!
Me: I wonder how heat powers those pistons
How this engine actually works is it turns heat into rotation
Me: thanks!
The engine works by a temperature difference on either side of the bottom piston. When the temperature on one side heats up it increases pressure on that side. It then has nowhere to go, and it pushes the piston backward. The flywheel stores that energy (kind of like a kenetic battery), and it transfers some to the top piston that pushes cooler air back down (the glass cylinder on top is at room temperature). Since this cooler air is forced back into the chamber on the cool side the difference in temperature is maintained. The flywheel also pushes the bottom piston back, and the hot air (on the hot side) forces it back down the tube to the flywheel. The top speed is reached when the two forces start to equal it out (The flywheel cannot store anymore extra energy). That covers the heat portion.
Now for the mechanical side of things where the energy is turned into rotational. The piston has a rod attached to to bottom of it on a swivel. That rod connects to a round wheel near the outer edge on another swivel point (think crank on a boat trailer). As the rod pushes (strait force) this causes an imbalance of forces on either side of this wheel, so the rod pushes that side of the wheel. The bottom side of the wheel is still part of it so it moves in the opposite direction as the force is equalized (distributed equally across the wheel). This creates a turning motion A.K.A rotation.
This is oversimplified, but I hope it helps.
You’re melting the piston because you’re adding the heat faster than the heat exchanger can dissipate it. That’s also why the entire thing is hot. This engine isn’t going to fail by blowing up; it will fail by failing to expel the heat
With a different (bigger) radiator, and perhaps different gasses, you can increase the rpm. But 4,000 is the max as currently set up - the exchange of heat will not allow to go any faster than this based on current setup
Definitely good to know the limit.
My pet project is to have this spin fast enough to power a 5v 1A usb charger module (via a capacitor to regulate the voltage)
the swedish navy use sterling engines to power submarines, and used one to 'sink' the USS ronald reagan in wargames
That's very interesting, I'm going to have to look that up.
At first I was like 'wait, what, that doesn't make any sense!' and then I remembered how damn quiet a sterling is when it's not being pushed to it's breaking point.
You get one balanced and greased just right and that thing makes basically no noise.
DFX2KX and you think nuclear in subs is noisy?
They are compared to a Stirling engine, nuclear reactors need a lot of coolant and the pump are pretty noisy
Insane video insane camera work
You can get more power and RPM out of it by using a can of freezer spray on the other cylinder and piston at the same time as using the blow torch on the hot cylinder and piston. The bigger the temperature difference between the two is the key. Thats assuming the freezer spray is not flamable. Love the videos
That was pretty cool! Curious if it would have turned a tiny bit more rpm if you took the generator belt off... I would think it's creating a little bit of drag on it, especially being overdriven like it is too.
I would be very interested in a Torque and Power v RPM curve for this engine...
I really don’t understand how the heck this engine works
iWantSomeBuns 69 hot air expands and pushes the piston down and you the cold air pulls the top piston down and it’s just a cycle back and forth until there’s no hot air on the hot piston
basically:
Air on the hot side (where the candle/torch is) wants to expand, so it does so, pushing the main piston down. that main piston isn't quite as big as the cylinder, so some air slip around. That air is pulled up into that second cylinder to cool off (the one on the top), once this cooled air is pushed back down, it moves back past the piston to the hot side, rinse and repeat. There's a 90 degree delay built into the engine to give the air some time to move. The colder the cold side gets, the more air it can pull in and cool, and the more air will be able to go back and expand in the hot side.
Therefore, the greater the difference in temperature, the greater the RPM.
I do not really like Stirling videos like this, where the speaker do not know too much about that hot air engine basically, but it was a great presentation for the limit of this engine. This alpha displacered type engine is a nicely machined one, and fast. You could increase the speed easily with some wet cooling on the machined aluminium part, but if you can fix the stand first that gives you a much higher speed basically without more heat or cooling because you stoped the negative resonances. Also you should take off that rubber O ring from the generator, that has a pretty high friction. Anyway, the video is cool, good job man! Greetings from Hungary! BLADE
Thanks! Well I know somewhat how about Stirling engines but I have to keep the verbage simple so everybody can understand.
now that you comment I did want to put a link to the stirling engine in the description and I completely forgot.
As for the little generator, you are absolutely correct oh, I could have got more speed if I had disconnected that belt, I totally could have done that, but this was the very first test and I didn't think it was going to melt the displacer. I'm glad you like it thanks a lot, I'll probably have a couple more coming up soon.
@@WarpedYT I see, people do not really know how it works basically. It's a "mystery", but few popular thinks later everybody wants change the whole world with it, but they don't know why not possible to change it... The stand fixing, the rubber ring, the cooling, and a heat trap what save your red silicon O ring sealing also reduce the heat transfer to the cold side will give you more than a 1000RPM I guess. Good luck! BLADE
3:10 most beautiful thing I've ever seen
☝😎
This engine is almost as powerfull as the 5,000 RPM motor!
nice teaser at the end! Can't wait to see what that's all about!
Stirling engines give me all kinds of ideas on how to make them work more efficient and in a car. There are all kinds of modern technology that could be used like ceramic coatings to insulate hot and cold sides even metal gaskets themselves could be coated. Metallurgy has improved so you could run a thin low tension gapless piston ring now.
Stirlings are more suited for constant RPM so in a vehicle it would probably be best to maintain RPM to drive something like a generator for an electric motor.
It needs to be powered by something so why not the exhaust of a little 5hp engine that could power accessories like the alternator, powersteering, waterpump, air compressor to charge the crank case. If you made the top of a Stirling into an old style catalytic converter (new style is a blow through) it would hold the exhaust heat on the Stirling head. Or possibly make it a flat pancake converter that goes around the base of the heated head so heat would rise into an insulated chamber and trapped to heat the upper cylinder. I need to stop thinking....
I agree with eternal ponderer below. The limiting factor is probable the engines ability to expel the heat from the other side. Very cool video (I love the 360' slow motion) and Yes, I'm gonna buy one but I won't be blowing mine up. :)
The cold side piston is probably graphite, made under the airpot brand - look it up - virtually frictionless but with a really tight seal
With the extremely rapid reciprocation of the piston, and the additional friction heat that likely created, I'm not at all surprised that it deformed. I am still surprised that the cylinder didn't, however... Regardless, I found this educational, and highly entertaining.
Yes same here! I am also surprised! Seems like it's made with the same material too!. Probably has something to do with the hot gas flow path through the cylinder, pulling the heat away from the cylinder around the piston and into the heatsink oh, that's my guess.
6:45 I'm thinking more of the lines of a weird sex toy rather then an ice sickle lol!
Hahaha I knew that comment was coming, sooner or later.
@@WarpedYT LMAO
Love this engine, just bought one for my 9 yer old for Christmas.
Maybe it never took off commercially because of the lack of torque!!
Good Vid :-)
Happy Thanksgiving to your family Happy Thanksgiving everybody🦃🦃🦃🦃🦃🦃🦃🦃🦃
Thank you, you as well!! Happy Thanksgiving
That is so cool Not a bad price either! Hey Are you still going to do a Electrical Fire demonstration? I think you should make a 8ftx 4ft wall and short the wiring some how or so Electrical over load to demonstrate what happens inside the wall when wires get super over heated/Overload.
Yes I am , now that you mention it I'm going to move that up on the list ASAP!!
Put a heatshield between the hot bulb and the cooler so you have bigger temperature difference. Moreover you can make the cooling area bigger or just use dry ice. That'll give you a real boost to your engine.
hook up a multimeter to the leads on the DC motor to see actual power output, also try running high pressure air over the second cylinder to cool it
This clinging compressor noise they make at high speed - sounds healthy when it's intended...
Its funny seeing all the other sterling videos on UA-cam, nowhere near as fast as this boi went.
I can imagine you wanna pump those rpm up even higher.
Im thinking a full on oxy torch is in order. Might just cut right through the glass though haha
Je pense être le seul Français à regarder cette vidéo
Continue j'adore ce que tu fait 👌🤘
Those camera shots where amazing.
Thank you
It's all about the torch heat source. On a larger scale a rocket stove with a valve regulated turbo.
Briggs and Stratton: Rated for 3600 RPM. Flies apart at 3900 RPM (We all know they do!)
Toy Stirling Engine: Rated for 400 RPM, Does 4000+ gives no shits whatsoever.
You have a little tiny generator on it! Awesome!
I have a couple suggestion's...1.wood gas powered go-cart...2.steam powered go-cart...do you think you can do it?
wow that's a cute little engine. Perhaps a few more revs if you put some ice on the chiller.
This engine making come back look at stirling energy generator project very cool. will replace air source and ground source heat pumps
I love your experiments. Dont stop making those videos💪🏻💪🏻💪🏻💪🏻🙏🏻🙏🏻
As a professional Oxygen Not Included player. I highly suggest a massive heatsink fluid? gas? solid? at the cold end, so it dissipates fast but never gets dangerously cool.
I agree!
I have a question. I would love to order this engine, but i live in macedonia in the city Skopje. Do you know if they deliver this engine to skopje?
