I am a student of agroindustrial engineering at the Universidad Surcolombiana (Neiva-Colombia), thanks to this tutorial I was finally able to build my Sterling engine to pass my general chemistry course. Many thanks.
Dude, thank you! This has been on my bucket list. I tried to build a different style a few years ago and it didn't work. I built this one to your specs and it worked great. I couldn't get it running at first but after reading comments and adding more heat to get it started and it ran great !!!!! (note to new builders, when you print the template measure it per included dimensions).

I would have fallen out of my chair laughing if you pulled out a torque wrench for the bolt/balloon. Just the thought of it makes me chuckle. But seriously, I'm enjoying watching you make this quaint little engine. Simplicity in design and contemplative silence all wrapped up in one. Good show.
This is a wonderful do it yourself video.Bless you for making it. The Stirling engine will eventually be the engine in most cars,as soon as "cold fusion" can be made to work. You will buy the car and it will have all the fuel to run it for its life inside the car.It will cost almost nothing to drive it.
i noticed that as well, a bead of thermal compound or even copper anti-seize (if more readily available) would transfer the heat to the heat sink more easily. and fasting to the cylinder with duct tape ( the real stuff, an adhesive aluminum strip basically) which is available at most home improvement stores.
Great video. i may make one of these over the weekend. No offence, but a touch of constructive criticism; i would try using two milk caps, tops of which facing opposite directions with the CD in the middle. and glue the edges (for set up time to be sure your on center. then you would have two points of contact on your crank, so you get less wobble. Thanks for posting!
horshak1 have the same problem - I really made it as exact as possible, no leaking, focused on every single detail (even better made that in this video), but still not working.
took your advice Roland and made a heavier base out of a tin can and used a propane torch. It did work till the torch burned a hole in the displacer can.
Part one left off in the middle of bending the crank shaft. This starts with the flywheel assembly and attachment to the crankshaft with the steel wool piston attached already. I would also like to see the heat transfer/valve physics diagram.
Today I made my Stirling engine and it WORKS! 5 years ago I did an Stirling engine with this same video and it didn't work. If your engine does not works, check that there are no leaks in the elbow or the union of the two cans, adjust the tension of the diaphragm and make sure that the engine turns easily. Greetings.
Good idea. I'll probably pass this along to a guy making a solar tube oven. I think he needs a gasket for high temp, I was thinking of silcone sheet (like for home baking), but the silicone in the tube might be very good also since can make it thicker and other things.
The point of this is to transform thermal energy (heat) into mechanical energy. Which means that you can use whatever hot thing to create movement, and that's pretty cool. You could even use it to generate some electricity (through electromagnetic induction).
Great job- I've got my hands a bit full with my charcoal gasifier at the moment, but I want to have a go. Suggestion- put lumps of Blu Tac round the flywheel as bobweights and watch it accelerate- you'll then have a little inertial dyno and can derive the horsepower. Or maybe mousepower :-)
I would have loved to be able to see a tiny bit more of how your displacer with the steel wool in it is moving once the machine works, furthermore it is a lovely project
I cant even remember right now, but it was most likely rubber cement, but the better kind is not the weak paper rubber cement, but one of the contact cement variety; which can be had for about a dollar at the dollar stores. I think I have the Bazic brand.
It's a external combustion engine. Converting one source of energy in to mechanical work. In these case use air like a fuel. Try to imagine does this disk is a car wheel then calculate how much you paid for fuel to drive? That is a point! And that is what this do. Generally you can find much more about this at section "Science and Engineering". Sorry for my English ;-)
Wouldn't it be a better idea to use metal-wire instead of some transparent thread? Because that transparent thread could melt, couldn't it?! However a very good idea on how you built it.
You need something that won't melt or char. You might try making a balloon of aluminum foil wrapped around a section of soda can or a wire cage. The displacer just has to be light and bulky. There is a more ambitious Stirling engine design called the "miser" that runs on very low temperature differences, such as a cup of coffee. Those can use plastic foam. The best versions will run on the heat of your hand.
Well its like a standard engine, you can attach anything to the flywheel, only if the engine can turn it, if you add more heat, it should spin faster. Like adding more fuel to a car engine
where is the plastic pipe placed? over or under the piston?is it placed completly under the main piston so that the air of the pipe pump pushes up the piston?
Please I have a question: Does the displacer (piston) have to be on the bottom of the elbow pipe or not? Is there any problem if it blocks the elbow air entrance as it moves up and down?
The balloon is the "power piston". The expansion of the air inside pushes the balloon outward, driving the crankshaft. The crankshaft lowers the displacer, forcing the air up into the cooler part of the engine. The cooler air "shrinks" and pulls the balloon inward, also driving the crankshaft. This raises the displacer, forcing the air back into the hot part of the engine, where it expands, pushing the balloon outward, driving the crankshaft, lowering the displacer ........ over and over again.
Or will it burn from the flame? I know it sounds like a stupid question but I don't have any steel wire wool at the moment and really just want to build this. And if there are any other substitutes for the displacer I would love to know!:)
Good present idea for my petrol head brothers coming 40th. I'll use a white disc and print a mag wheel with tire on in so he can sit and watch it go around and round.
Does anyone know if I can replace the metal wool with something else? I don't feel comfortable putting a hot flame under a metal wool. Isn't that how camping people start fires easily?
Pretty clever design though. I've come up with one too (check it out on my account). I was debating using a balloon as a "flexible" power piston, as you did, but i didn't think it would be strong enough. I ended up pouring a JB Weld piston in a copper pipe. Very cool, from one budget builder to another, I'm impressed. (for everyone else, the steel wool is acting as a "Regenerator". It saves some of the heat from the expansion stroke, and re-introduces it into the system, so that not all o
Mine did'nt work too after making the engine the way shown in the video. I then tried checking each part. Firstly, the displacer moving up is not blowing up the balloon piston at all, all combinations of tighter , lighter, longer displacer still doesn't move the balloon up. That's the starting point. I guess I cant move further till I fix the first problem. Any suggestions?.
I think, the additional heat sink won't help that much, when attached like this. You should try to put it "directly" at the metal, not on top of some tape! (The tape is isolating)

SIMPLE IDEA coming in practice gives great result and inspiration for other young pioneers, CONGRATULATIONS

Totally wicked!!! I am impressed... There are so many places where you used creative thinking to get the parts you needed. You have a gift!

Well done young man I like the way you made you made the chamber for the t-light candle, simple but very effective good work.
Awesome! I like how you use all readily available materials and techniques and manage to put together a working engine!
i noticed that as well, a bead of thermal compound or even copper anti-seize (if more readily available) would transfer the heat to the heat sink more easily. and fasting to the cylinder with duct tape ( the real stuff, an adhesive aluminum strip basically) which is available at most home improvement stores.

Made a design inspired by this one, worked amazingly!
I made one. It took me a few days but got it done and it worked like a charm!!
would like to talk to you as I have had no luck getting either of the two engines I built to run.
OK, I'll be glad to help if I can!
Roland Marissen I found one candle was not hot enough. Try more heat!
horshak1 have the same problem - I really made it as exact as possible, no leaking, focused on every single detail (even better made that in this video), but still not working.
took your advice Roland and made a heavier base out of a tin can and used a propane torch. It did work till the torch burned a hole in the displacer can.

heading out to buy the balloons and dig thru the neighbors recycle can for soda cans now. Thank you for such a great video.
Today I made my Stirling engine and it WORKS!
5 years ago I did an Stirling engine with this same video and it didn't work.

Built my first one half ass. Ran pretty good. Built 4 more taking my time and following instructions Never got one to run at all.......
The point of this is to transform thermal energy (heat) into mechanical energy. Which means that you can use whatever hot thing to create movement, and that's pretty cool. You could even use it to generate some electricity (through electromagnetic induction).
I made one using a beer can for the cylinder shape and covered top/bottom with cardbord. extremely light and efficient too:)
Great job- I've got my hands a bit full with my charcoal gasifier at the moment, but I want to have a go. Suggestion- put lumps of Blu Tac round the flywheel as bobweights and watch it accelerate- you'll then have a little inertial dyno and can derive the horsepower. Or maybe mousepower :-)

My compliments....I most entertaining and well thought out project...I like.
I love sterling engines. The balloon diaphragm is the best thing in the whole world to me.

My friend ... Your displacer is great!!! Using a metal wire will better ... But the nylon is more simple !!! Great!!!
Thank you for changing the name. I appreciate that. -Jim Larsen
HANG ON NOW!! Am I to take it that in the UK one can acquire a Dandelion and Burdock soda or tea, in a can??? Marvelous!!
dude that's wonderful , u r SMART ;) good luck :)
u gave me a lot of smart ideas today.
You need something that won't melt or char. You might try making a balloon of aluminum foil wrapped around a section of soda can or a wire cage. The displacer just has to be light and bulky. There is a more ambitious Stirling engine design called the "miser" that runs on very low temperature differences, such as a cup of coffee. Those can use plastic foam. The best versions will run on the heat of your hand.
the ballon should be more tied to the plastic, but i can see how easy for u to do this now, i have been following you since first one :) good work
Congratulation for your video. Can I use a 25 mm pipe elbow?. Thank you.
This is just amazing, i will build one of this glorious engines. Thx for this tutorial.
thats wonderful. im going to try one
how well does the heatsink work
Well its like a standard engine, you can attach anything to the flywheel, only if the engine can turn it, if you add more heat, it should spin faster. Like adding more fuel to a car engine
I followed every instruction page and today I do this I would successfully be performed
where is the plastic pipe placed? over or under the piston?is it placed completly under the main piston so that the air of the pipe pump pushes up the piston?
Please I have a question: Does the displacer (piston) have to be on the bottom of the elbow pipe or not? Is there any problem if it blocks the elbow air entrance as it moves up and down?
Neat. I'm a complete novice, but I did have a question. What is the purpose of the thin strips of aluminum outside the cylinder?
What did you put around the hole on the displacer can? it looks like scotch tape, but I'm not sure.
I can hear it was raining there, I like it when it's raining and making things at the same time, it's a cool feeling
The balloon is the "power piston". The expansion of the air inside pushes the balloon outward, driving the crankshaft. The crankshaft lowers the displacer, forcing the air up into the cooler part of the engine. The cooler air "shrinks" and pulls the balloon inward, also driving the crankshaft. This raises the displacer, forcing the air back into the hot part of the engine, where it expands, pushing the balloon outward, driving the crankshaft, lowering the displacer ........ over and over again.
Hey great vid. I built this model but I'm having trouble getting it to run. Do have any troubleshooting tips?
It looks like the crankshaft is pulling on the wire in the steel wool. What purpose does that serve? Why does the steel wool have to move a bit?
Sure they can... I used steel wires of 0.8 and 1.4.. and it worked nicely
Other than the annoying wobble on your cd,I think its pretty damn nifty!To hell with the idiots with snide remarks,good job!
Could be air leaks around the pipe elbow ? Or the hole for the nylon wire is too big, those are the most common problems with these engines.
Hello , I compiled a motor exactly as directed balloon but I do not really know what to inflate but substituting ?
Or will it burn from the flame? I know it sounds like a stupid question but I don't have any steel wire wool at the moment and really just want to build this. And if there are any other substitutes for the displacer I would love to know!:)
Can you explain what the wire/string in the steel wool does?
found everything but the wide double stick tape. Went to Lowes and Ace hardware then tried Office Depot but no luck on wider than 1inch tape.
Specallez, can i replace the cola can with some smaller diameter can as well as the piston?
the way I like your work very well trained
So the air inside cooles faster and the engine can run for longer. It also helps it run a tiny bit faster
congratulations
simple engine with super ideas !!!
question! does the steel wool get burnt since its placed directly above the fire?
for those who could not make it work just make sure there is great difference of temperature in your can holding the piston i even put ice in mine
Good present idea for my petrol head brothers coming 40th.
I'll use a white disc and print a mag wheel with tire on in so he can sit and watch it go around and round.
This is REALLY NEAT!! Kudos!!!
do u think by adding fins to the cd making it a fan would aid cooling thus improve performance?
Why is that the wire connecting crankshaft and displacer must be soft (nylon), but wire connecting crankshaft and power piston be hard(steel)?
Why is it that you decided to use that soft fluffy metal thing as a piston, instead of having a regular solid and lightweight piston?
Does anyone know if I can replace the metal wool with something else? I don't feel comfortable putting a hot flame under a metal wool. Isn't that how camping people start fires easily?
its not gonna catch fire or anything...its made of metal..i think those people use wooden wool or something....
Pretty clever design though. I've come up with one too (check it out on my account). I was debating using a balloon as a "flexible" power piston, as you did, but i didn't think it would be strong enough. I ended up pouring a JB Weld piston in a copper pipe.

All together, what would be the total cost of all this stuff? (Minus the cans and lid)
Mine did'nt work too after making the engine the way shown in the video. I then tried checking each part. Firstly, the displacer moving up is not blowing up the balloon piston at all, all combinations of tighter , lighter, longer displacer still doesn't move the balloon up. That's the starting point. I guess I cant move further till I fix the first problem. Any suggestions?.
I can't seem to get mine working. Can I buy three of these?
Very very clear...!!!... Thanks a lot!!!...
What's the heat sink for? Does it make the cd spin faster
Can you put small fan blades on instead of a disc to make a fan?
I don't see why not.
Why pointless? Good way to understand how physics work. Nice work!
Hey specallez, do you mind answering this question for me?: can I use foam as the displacer instead of the steel wire wool? Thx!
what do you need the fishing line for
man this is amazing. surely gonna help. i'll give it a try
The videos are great. Awesome school project. But let's all take a minute for all the soda lost in the making of these videos.
Thanks for the silence in the video, it's like a nice break of the loud world.
The steel wires can be of similar thickness? It's because I can´t find of 0.6 mm and 1.5 mm... /:
I don't have steel wool, what can replace it? Phnom Penh, Cambodia
Nicely done, boy !
from what I have read you can get an engine like this to go over 9000
So what does this exactly do? I mean what would you use this for?
Great Job! Nice and easy, love it!
This is excellent I want to make mine like this one
How if the piston too heavy? Can it move? Specallez!
How tight/ loose is the balloon?
I think, the additional heat sink won't help that much, when attached like this. You should try to put it "directly" at the metal, not on top of some tape! (The tape is isolating)
I also made this but mine was not working the piston is not moving,i tried it many times...can you tell me what is the problem....???????????
do you have one for sale?
ALL HAIL TO THE POWER OF TWO SIDED TAPE!
Do these run on fuel? :s or just hot air?
:O lo hare para mi trabajo de Fisica!! muchas gracias por compartir esto! saludos ;)
Nicely done by the way :)
would you be able to explain how this works?
is it possible to create this on a larger scale?
Yes but the larger engines will need some larger energy source.
A couple of wraps with a rubber band should be able to seal the baloon to the pipe easily.
Good job you should be got a medal
;)
you are a pro!!!i want to make a big one!!
Very good. Good job!
whats the steel wool for?
