- I test this Stirling Model engine for an upcoming episode to see if it's just a toy or a functioning engine with an actual service factor and working heat exchanger like the full-sized real-life version of the Sterling engine.

can you film a stirling engine in slow mo
Brother! Your videois beautiful,
Would be cool to see you build an engine from start to finish
*HEY!! Did nobody notice that giant version of the see-through engine right next to him on the right hand side??? WTH*
Nice observation!, Good eyes 😍.
No not on my first watch
I did look at it but I did not focus on it
If you load the little generator with a resistive load, you can measure the voltage and current and use it as somewhat like a dyno.
exactly what i was thinking but much more extreme!!! great minds think alike!
@@WarpedPerception I have a design in mind for a larger more permanent engine, if you want to discuss sometime.
Sorry I haven't posted in awhile, since I guess the electric arc video slowmo inside slowmo.
This was a great engine, much better than the one I bought, where'd you get it?
@@ShifuCareaga nice I'm always down for a discussion, I looked on your channel but I couldn't find the electric Arc video.
This engine sounds a bit like a small vw diesel.
Rc Dude '04 nah it puts out less harmful gases
@@harleypickin217 true.
just imagine if this engine has its own internal heat source it would run forever
@@alphayun7401 it would never make enough heat to run the engine .
@@dixie_rekd9601 u
I figure either lack of cooling or lack of lubrication will be the end of it
add an oil dropper on he hinges, and water cool the heat exchanger and it will run forever
After an Hour the sytem has itself stabilized, only wear and lack of lubriction could cause a damage.
Yes, the flame any hotter and the engine get's thermally overloaded, but as is, runs fine.
What I've know from thermodynamics, they were on the engine's side this time.
It would be kind of neat to see a stirling engine powered by focused sunlight of a parabolic mirror, to illustrate its application field.
Interesting video as always, greets Zigzag
I completely agree that would be cool
They exist. Look like satellite TV receivers. More efficient than solar panels at generating electricity, if I remember correctly.
yeah or cooled with water and fuel with diesel :P the other field where those are used
Giin Sure, they exist, thats what I meant with illustrating the application field. They may be a bit more efficient but have the downside of requiring direct sunlight in contrast to traditional solar-cells, which work with for example by clouds deflected sunlight as well.
@@zickzack3106 gotcha. I misunderstood.
entire engine looks classy af
you need a temp gun so you can check the temp and not keep man handling the engine while it running
He was feeling how much torque it had
Man... $80 for that little engine? With that level of details and finish quality? Dang that's a good buy!
Completely agree!! I though so too !! And on top of that it runs like a dream.
I think i even saw it for like 60 bucks on Aliexpress.
Idk how it's even $80 in my country if I go to buy just a piston it will cost me $80
I've never heard of it before. I'm going to have to check it out. Thanks. Another awesome video!
This was a genious idea for a video! Loved it! Very cool! Good to see ya again! 😎😎😎
Thank you !, I was very busy shooting storm stories for the last 5 months but I'm back on YT now, I will release the cymatics video soon as well I'm just missing one very important scene at the end. That's the only reason it hasn't posted yet.
@@WarpedPerception i'm so happy you're back! You're welcome! Np! That is really cool! Can't wait for it! 😎👍🏻👍🏻
Really love your videos. Thank you.
The engines principles are based on a difference in temp between the cylinder and the flame. The gas flame will always run hotter than the cylinder does. Hence it would theoretically run forever. That's my understanding anyway. :)
I think you're absolutely right, I realized that shortly after this video after I thought about it for a minute. I'm assuming eventually it will reach its peak level of inefficiency and minimum power output, and if that number is enough to complete the cycle, then it will keep on running that way.
I would be more concerned with carbon build up on the hot side.
That carbon is on the outside. Shouldn't hurt anything
It does reduce the overall heat a little bit
@@ballHand not necessarily. Once it gets warmed up the carbon would act as an insulator and help keep heat in.
@@cokebetterthanu50 carbon is one of the best insulators due to its infrared radiation efficacy, so no, it will cool down the cylinder.
Glad to see you again!
im sorry, I was filming Storm Stories www.imdb.com/title/tt10868066/ for 6 Months...it was an intense amount of work ! thanks for your patience!
I've built several of these out of trash. Literaly!!. One time my flywheel was actually a peanut butter lid. The displaced was a tin can. And the crankshaft was made from a bicycle wheel spoke.
you could see how well the engine is functioning by hooking a multimeter up to the little generator.
Gracias ,todos tus videos son muy buenos ,un saludo desde Barcelona, Espana
Gracias !!!, Muchos saludos!
Lower the heat, what's the most efficient burn you can get per voltage generated. This is the question that really needs answering. Let this run for days. Weeks. Measure it.
It is about the wattage rather then voltage. The voltage the generator produces is dependent on its RPM. Stirling engine is not the most efficient at the highest RPM.
Phillips -Holland- back in 1953 had a few running just after the big flood in the Netherlands, hooked up to some generators for electricity, to aid in the clean-up and rescue operations. They owned the patent back then.
They even had some buses running in Eindhoven. Obviously there were some snags with this motor as they stopped developing it and sold the patent -I believe to Ford, but I'm not sure. Also the original design this guy's talking about was quite, quite different. It was much more vertical design.
Thank you, is this an alpha type correct?
I understand your thinking: it does not lose enough heat. And I agree, there should be more cooling applied. I guess the reason why it manages to keep running cool enough is, next to the radiation of heat, the air from around going in and out the piston's cylinders.
Should of hooked up a multimeter to the motor!
I will in the full episode also an infrared thermometer!
I love these little Stirling engines. I have a practical question, and an idea for a cool video, I would like to know what the easiest way to modify one of these engines is to produce 12v dc via a motorcycle alternator, and also which commonly available fuels produce the most energy.
I like your videos, please post more!
Thank you I am planning on posting everything now 😊! Thanks again
Cute little Stirling engine
Cool video
Old school cool . Old design and still useful depending on how they are used .
My first time seeing a sterling engine.
Nice !!! Hope you liked it
I have a low temperature stirling engine which is little more than a toy, I can set it on top of a hand warmer and it will run continuously for hours, I've even had it running overnight more then once.
Спасибо! Отличное видео!
do something crazy with a large one now, for science
hahha,,, you know it!, but first this little guy, but before that, the see-through engine episode 7, Nitro, Turbo and EFI. should have it all running tomorrow, I will be making an update video tomorrow as well.
I just ordered one ! I hope to receive it soon ! :)
Awesome 👍, I'm sure you're going to like it I was blown away by the quality
@@WarpedPerception Nice ! I love your video man. Also I am going to put a video of this engine with thermal camera footage when I receive it, so we will see the exact temperature distribution on the engine !
I want to totally use the thermal imaging camera in the actual episode that I have coming up. It's going to be fun, for sure send the video to me I'm curious
Can't wait for a super high-tech and modernized version of a Stirling Engine.
Older Stirling engines were used on fans. You can get a stirling engine fan that would run on kerosene and it would go as long as you had fuel.
Truly impressive piece of equipment.
I have seen those, what I really wonder is, how much fuel would you have to spend to run a fan versus just running it on electricity, I mean how much cheaper is it to run electricity from the power plant versus burning natural gas yourself making that conversion to electricity, in the winter months maybe even using that heat that's left over from the stirling engine to heat your house. You never know
They make them for wood stoves.
@@WarpedPerception with a fan you can calculate how much air is being moved, then calculate how much it costs to power that fan for x amount of time, and figure out how much it would cost to use natural gas so you can power a stirling engine fan to move the same amount of air over x amount of time.
...
I would assume that natural gas is cheaper than electricity. furnaces in northern states burn some type of fuel to heat the houses because it is almost always cheaper than using electricity to heat the same area under the same conditions.
True story time...
My last apartment was baseboard electric heat, the electric bill was far more expensive through the winter, than the gas bill in my larger home to heat a larger area.
More story time...
I live up in Minnesota, I've had at least one friend who lives far Northern Minnesota, he Sam's and splits all the wood from the trees he cuts down on his property, plus he gets more wood from other trees that are cut down in the area. He uses that wood to fire his wood burner and runs that Heat with an electric blower fan through the ventilation system in the house, as well as heating the water in his water heater. He originally had 5 ceiling fans on one common motor with a huge belt system running to the house to move all those fans. It would have been awesome to see all that run on 1 high torque stirling engine if there is such a thing.
Dave Pitsch electricity is cheaper I think. Here in Germany it’s 3x more expensive than natural gas. But electrical motor is 50-98% efficient. Stirling is maxx 16-20%. 1/3 third of Carnot I believe
@@David-cy5zu that does make perfect sense, other ways they can be used to increase the efficiency would be if a stirling engine fan were placed on a warm air duct or some other wasted heat energy place, capturing the heat energy to use as fuel for a Sterling fan would make it very efficient.
Maybe use a thermometer, so we know what temperature.
Cool!
How many RPMs can or does the flywheel turn? Enjoyed the video, as always.
It acually did pretty damn well.
Where do you get the little glass cylinder cover? Where do you purchase them from? Mine broke.
You should really keep it regularly oiled if you are gonna run it like this , also you could move the flame to the very tip of the hot cylinder, and make it smaller,
You are absolutely correct, but let me clarify, for one I didn't think this engine was actually going to be fully functional, I thought it was mostly just for looks and minimal function. As for the flame you're absolutely correct, but I didn't want to run it too slow, because I wanted to run it through a more realistic test so I know if it's going to hold up for my episode before I go through all the trouble of setting it up. I have something very extreme in mind for this engine, at this point I'm pretty positive is going to be awesome.
As long as there is a temperature difference...it should run. It would be nice to see one of those with ball bearings on every wearpoint
Would it run with a/multiple power LED('s) on the heating chamber which is powered by the dynamo? Nice little machine!
muy fino, felicidades
Potentially make a electric generator power a fan to cool the heat exchanger and make it run quicker? Just a idea.
note the air flow, from the flywheel.cooling the cold side. reducing the convection from the flame, dose not hurt, either.
hm yeah but the amount is so little it is insignificant
You know them spring things behind some doors???
Reminds me of that sound
Finally
I like these. I cant tell if they have more torque than a flamelicker engine does or not. I think Im going to buy one and make it run from a flame fueled by kerosene like in a lantern.
Could you take a Fernnell (sp) Lenze from a projection TV to power a larger sterling engine to power a commercial size generator? I live in the heart of the Mohave desert. Daytime temp a little low for this time of the year at 107 but I have seen it 120 here on the Colorado River.
Would be interesting to see a Stirling engine being run from the sun in some way. Maybe with a parabolic reflector 🤔
magnifying glass works
They exist
you should do an experiment to take all freezed and isolated cold part of engine and extremely hot the hot part to se the maximum torque it can have
great vid, how's the efi turbo briggs going?
maybe max rpm test of stirling engine?
lol...posting an update video tomorrow on the Briggs, almost done, literally working on it today! LOL...you know my style wait till you see how im going to get max rpm out of this thing, I cant wait ! it will be very soon, I was busy Filming Storm Stories the next chapter www.imdb.com/title/tt10868066/ for the last 6 months, I've been missing youtube!
Your natural gas is burning too rich and the flame could have a little shield on so there's very little heat leaking over to the cold block. Also, a temperature sensor on the hot end and cooler end could indicate if you're in a steady state.
that heat exchanger looks like it has a decent heatsink but id try to find a better way to cool it if i were to try and make it run faster
A built in water cooler would be cool to remove some heat and a oil dripper
A stirling engine is a hot air engine stirling is the cycle
If heat saturation didn't stop it, lack of true bearings at those narrow contact pivots points certainly will. Would love to see a well engineered version designed with longevity in mind ..
Yeah, there will always be enough differential to run it if the hot cylinder is inside of fire and the cold cylinder isn't. You'd have to put fire to the cold cylinder to equalize it.
Yeah I didn't really think about that until later, but no matter what you will always shed heat from the heat exchanger and the cold cylinder oh, no matter what unless you heat them directly they will always be a lower temperature than the hot cylinder.
@@WarpedPerception Yup, that said, I was actually really surprised at just how much torque it had left after it hit steady state. With the cylinders that close, I would have thought it would peter out with just a little touch.
Sweet, I want one
Check out that link in the description area, you will get a discount if you use that link. Thanks!!!
@@WarpedPerception why thank you, shame I am so broke right now, however when I get a job, I'm going to get one.
@@ZeacorZeppelin maybe I can give one away soon !
This is strong engine nice
Very strong, very surprising as well, I'm really excited for the episode because now this engine has proven that it is up for the task I'm about to throw at it!!! I can't wait.
How do we know that little DC motor on the bottom wasn't hooked up to a voltage converter!?
Hey can you do the video on electrical overload fire? I have always been curious to see what happens inside the wall and so on when an electrical fire starts. you should do like a loose connection, then another one with like an overloaded wire with two big of a breaker and a few other electrical fire starting scenarios.
I will totally put that on my list. That sounds like a lot of fun
Makes you wonder how much you could capture by having a solar heated 'hot side' and harvested the work somehow via batteries or lift pumps or something on an upscaled version.
That would be awesome, I wonder if you would be able to capture more power than solar panels alone. Would it be more efficient?
@@BendingPhysics I think solar panels are around 15 - 20% efficient...The thought crossing my mind is have more surface area via a hot water solar and once running it could pump itself with anything left over as the harvest. Not sure how it would compare to panels, but it is interesting.
Sterling engines are incredibly inefficient, the date is out there if you want to see large scale versions and their super low efficiency.
@@otm646 Yeah, they've been around since the 19th century...I figured if they were better, we'd see more and that something was preventing adoption beyond curiosity. Thanks for validating my suspicions.
@@otm646 hmmm... I thought I remembered solar Sterling engines to be more efficient than solar panels of the same size collector, but the downside is the high speed moving parts. Been a while since I read up on them, could be wrong.
would have been fun to see this with a thermal camera
what about a huge stearling engine on iceland? put the hot piece into a lava sorce, watercool the heatexchanger with the cold water from the ocean and have the thing run foever and make free energy basicly
That's actually a cool idea
@@jaynee8581 cool/ hot , depends how you look at it haha sry for the bad pun but i had to. watch it be done by some big company somewhere, and il f my self for not patenting it
You can also put ice on the end of that thing and it’ll still spin
I wonder what is that little engine/dynamo??? used for
Does it still work even if the thing above the flame is completely black ?
I jave one of thoes and i use the small DC motor as a starter/generator.
That's a sterling video about a stirling engine 😉
Thank you
How to maintain the torque and rpm? Any trick or idea
Use a frenell lens and focus the sunlight.
Is it OK to run these for an hour? Or will the glass tube break from too much heat exposure?
Wanker
Dawgone, how many rpm's does that thing crank? That's a pretty decent price for that setup. I have a really basic sit on top of your coffee cup type sterling engine. It works pretty good but is that nearly as cool as that machine. And it was almost 50% the price of this much nicer one.
Faster than the frame rate of the camera, and watching it cross that was cool.
I think this is the engine I want to use as a “plant engine” outside on the back yard, up on a post, exposed to the weather, running the flame on kerosene and driving a slow pump to bring the kerosene to the reservoir from a tank, to keep it running continuously.
ca you run one of these by shining a magnifying glass on the end of the heat exchanger?
Theoretically yes, practically maybe? These engines don't need a massive amount of delta-t, but they have to have enough energy to overcome the friction of the components
You are using far more heat than it needs.
sure is
So the torque lessens as the difference in heat lessens?
exactly, thats the idea, the cooler the heatsink stays and the larger difference in the temperatures the more efficient the engine is.
Here is the other problem i see, that flame is far too large, even the original one was. you need a smaller heat source for this small engine to keep up indefinitely. You need to find the smallest flame that can keep it running that will keep the temperature difference in such a way that thermodynamically one will always stay cooler than the other and will never get over a certain temp on both sides. Yes in theory it ran constant for over an hour but eventually with a flame like that from natural gas or LP it will all become the same temp and start to become so inefficient that it will sputter and quit
That's exactly what I thought as well, I'm going to finish up the episode with it, and then after that I'm going to do a follow-up video where I run it continuously until it stops, I'm just trying to figure out the technical challenges involved with filming that.
Its all theoretical but it makes sense at least in my mind thanks for the vids they are awesome
I have same type of stirling engine and it stopped working after minute it’s running.
That flame is *waaaaaay* to that glass tube
Wow
how long can it run? we dont know he turned it off after 3 hours.
water cool the heat exchanger , it will run forever
You didn’t even use the generator ....
Could have powered a small village with that thing
Hey the first time I saw this from Dr. Stone
Dr. stone? I'm going to look that up
Could you run a radio or led lights or charge a mobile phone.
What if you wrapped copper wire around the class bulb and sent electricity to it to keep it hot and just out it in the wall last longer be cheaper than gas
That's a great idea, I may have to try that !! On second thought that's an absolute fantastic awesome idea!.
@@WarpedPerception cool man i was thinking you could control the voltage and that would control the heat maybe you could vary the rpm by controlling the heat maybe it will run longer. 👍👍 Love your videos man
How long will the discount code be on?
I believe for 6 months. I'm going to use it again once I film the full episode!. It's a really good deal actually.
I know it dos not make a lot of power. But is there any way you could measure how powerful this engine is?
I was thinking the same thing, like a little Dyno or something.
It would be cool to see a thermal image of the engine while this was happening.
I agree, I will in the full episode !
@@WarpedPerception sweet
Would be cool to see this hooked up to a small generator which could charge a cell phone....
Me when I accidentally bend the thingy on the doors at 3 AM
Buying lobbies 220 gp ea-------------------8 ball181
selLlLinG LoBs 200 eaCH!!! - hobbitman00
U think if the flame was turned down some and the radiant heat wasn't as hi it would have lasted longer?
Well it lasted too long for me. But in the episode I will push this thing to the extreme
@@WarpedPerception yes and most tests that last over ten minutes I am on to the me t video but I am very intrigued by this engine just ordered myself one
What about an infra red thermometer!
it's coming in the main Episode, this was meant for my Personal channel but I ran a poll and everyone voted for me to post these here so here they come !
Will not work on shiny metal. Better contact thermometer.
Did you notice it moved on it own when you put the propane to it?
Yes it always does this when you go to start it
as long as you supply heat to a Stirling in an open system there will be enough difference in temp to keep it running. Unless you melt it.
Stirling engines are closed system by definition
@@eifionjones559 Okay isolated if you want to get picky
Yeeeeee and may I enficize HAWWWWWWWWW
Well, yeah. The two parts can't have the same temperature to kill the cycle if one has a flame and the other has a heatsink; that's not how physics works. You'd have to have the ambient air at the same temperature for the cycle to stop, and that's not going to happen in the open air.
yes true, but this engine is the gamma type I believe, Closed-loop and does not use the ambient air for anything other than cooling the heatsink. I will triple check as I havent taken this engine apart just yet, but I think thats the case.
Actually I just thought about your comment, and yeah you are completely right, as long as that heat sink is a lower temperature than the hot cylinder there will always be a stirling cycle to some extent. Even if the difference in temperature is minimal, just the efficiency would drop and the power output would drop significantly, but you would always still have the cycle. for some reason I was thinking ahead into the actual episode that I'm writing for this engine where I show that concept, but I won't give it too many details here and spoil it.
I am trying to find out if you can run it long enough to charge my phone
