I also build Sterlings and others but have a hard time finding bearings. Where do you get your open cage miniature bearings. Great work on this engine. Isn't it satisfying when you see it run for the first time? Have a good day.
Okay, first, you appear to be a fine mechanical engineer. I'm quite fascinated by Stirling engines but I've been disappointed with their power output. I do not have a Stirling at the moment and most likely will not have one in the near future, but I was wondering about the generator. There are so many moving parts on this device. Couldn't a quantity of electrical power generation be incorporated into the flywheel itself instead of dragging it down with another mechanical component?
Yes, you're right on all accounts. this engine is completely dependant on free moving parts and it took a lot of work to get anything out of it at all. This particular engine is very weak. Also, I've had plans for quite some time to put magnets in the fly wheel in a three phase low cogging configuration. As example: 14 magnets in the wheel and 12 small coils facing the wheel should provide something like 84 pulses per revolution to the rectifier.
@DadHav Would like to see how that works out. Please gimme a heads up if you post a video with that configuration. I live in Florida and there is so much heat down here that a properly designed stirling engine generator would probably give my solar panels a run for their money :-)
Great video I am building one of these from an old four stroke model airplane engine and am almost done, I took the ring off of the piston and now the engine spins nice and free but has a near air tight seal, now I just need to build a deacent displacer unit, I plan on powering a small town like set up with belts driven from the engine, saw mill, wind mill, water fountain maybe
@DadHav I'll post it when its done, the engine would only work with a four stroke airplane engine because it unlike a two cycle has a solid sleave cylinder, the two stroke ones have intake exhaust ports in the cylinder, my engine was old and worn out with a broken valve spring and very little compression so I figured it would make a good donor engine for the project, I'm still going to try and use the prop for the flywheel.
hi i love this stuff, is there any reason why you can,t create a greater temp. differential for these engines by using the heat source to double as a cooling source the way its done on gas fired refrigerators?
Sal. If you want to come on my channel and make a fool yourself, you are welcome to do so any time you want. I think you deserve it. For your information the generator on this Stirling is a DC motor with a commutator and brushes. When you run any permanent magnet motor with brushes by hand it turns into a DC generator. but this has nothing to do with your nasty comment. If you have something against me or my channel just don't come back, No one will miss you.
Would it make a difference if the wheel had some sort of weight on it that could help give the engine momentum and kinetic energy? If so, it could possibly use a more powerful generator.
A bigger flywheel might help a little bit. I'm thinking about adding magnets to this one and making it sort of an axial flux generator. The weight of the magnets might answer the question.

Really enjoyed your clip, the engine looks very elegant and although small it looks quite rugged. Good to see that you've actually demonstrated how it generates electrical power. Would this design generate useful power, say 100watts plus if it were scaled up in size?
I would think It could be scaled up but I'm not sure there isn't better designs to get more power. If I understand correctly, the old Erickson engines actually where used to run farm equipment, but the design was a lot more complicated than this simple engine. I was told the the UK has a submarine with a hybrid Stirling engine in it to be used as an auxiliary in stealth mode.
john man your epic i mean im only 16 and i like sice i found your channel, i honestly cant stop watchin what you keep making, no matter whether its an engine, generator or some random thing ive never heard of!
so looking forward to see what you come up with! :)
Thanks young man. I'm just an old man that's had a lot of time to learn some skills. My pleasure now is to remind viewers of a time when people had great pleasure and pride in making things by hand. No nuclear reactors for me though. I do have a ton of other things I'm trying to get to.
Beautifully made. I like the addition of the bearings and it's nice to see such a machine performing some work.
- I'm still waiting to see one running from the heat generated by a compost heap, pumping water from a fish pond, through a cooling jacket and back into the pond's biological filter, though. :)
Very nice machine. While I admire the ingenuity of some of the very basic Stirling engines on here, it is also very nice to see quality workmanship.
I also liked the attachment of a load, however small. While most engines on Youtube are built for novelty, the Reverend Stirling designed his engine to replace the steam engine and it would be great to see more engines doing real work. I am hoping to build an Ercisson or external Brayton cycle engine but these Stirling engines are also great.
Yes, Most of my models are meant to be book shelf displays, but It would be nice to use something a little larger to do a useful task. Let me know how you make out with any of your builds. I'd be very much interested.
What's a shame is smart asses like yourself feel they can use the computer to lay down screwed up comments anywhere they want and have anonymity because no one knows who they are. You're a disgrace to England and Ireland. I happen to respect the UK and it's flag and wouldn't go on anyones channel and insult them when I'm there as a quest. What makes you think you won't find someone to stick up for themselves. Don't come back here!
@mksav1 Why dont ya come over here and say it to our faces??? Thats right your just some dumb@ss behind a computer screen...Btw DadHav, Great engineering here
i enjoy watching your videos even though i only understand a small fraction of what your doing. thanks. i would love to see you build a steam/diesel high compression engine fired by cap flash within the cylinder with natural water circulation and have that little bugger driving a generator. sealed system. start and why wouldnt it run until it broke? i think you have a beautiful mind.
The motor really isn't very powerful because it runs on the air in the engine alone. The little generator is a DC motor from a tape drive. The flag uses about 6 volts and 60 ma. I would imagine the motor could run something at maybe 200 ma or so. I have plans to make an axial flux generator to be a flywheel and rotor. That may work out a little better.
It's usually better to be stroked than bored...and blown than injected. But when I get my mind out of the gutter, I do appreciate the attention to details. Graphite? Why didn't I think of that? Nice work!
I know what your saying. I've been drilled and reamed a few times in my tool room days. There might be a better choice than graphite for extended use but it works nice for this application.
Very nice engine! Could you pls tell me what is the distance between the work piston and the cilinder? Your engine runs very smooth when you push the flywheel and let it go and i don't really understand why. When you pull out the work piston it seems there is no vaccuum. Thank you for the answer and sry for my english :D
Hello. There's probably .0005 inch clearance. I think there is some leakage in the busing for the connecting arm on the cam as well as enough air inside the engine itself to make the suction a little less noticeable.
I'll bet you any money any time NOT. Let me know when you find some. But if your just stating in general that they can undercut any manufacturer in the world, I might agree with you. I've seen many of what would be a precision product from them and what you get at most is a kit that you have to rework to get right.
The parts kit and drawings came from TheLittleMachineShop. You can search and find it. The raw materials and plans where $69.00 at that time if I remember right. Of course I changed the design and used English instead of metric. The time in the machining is what makes it so impractical to reproduce. If you do a search on Ebay for Stirling engines you can find all kinds of kits and finished engines. That would help answer your question.
thats some very high quality work sir . i run a family engineering work shop in scotland with my father and i sure do appreciate some fine quality workman ship. tool making seems to be a dying breed over here but im still flying the flag for our fellow engineers lol , hopefully one day we will be in a position to help other young people to learn the trade . out of interest what machines do you use to craft your master pieces ? im a sucka for machines lol
Hello, It's nice to have something in common with you guys. We have the same problem here. I'm afraid we've seen the last of the Master Tool & Die Makers, at least as we know them and their skills.
My machinery is really only hobby size. I have a Grizzly G-0619 (S-3) Bench milling machine and an old 1940's 9" South Bend lathe. It's even flat belt drive. I just posted a video showing some machining on a Mag Lev Fixture. Have a look. Thanks for the compliment.
Wow, It's good to hear someone still has an interest in learning the trade. I'm glad your not worried about getting your hands dirty. There may come a day where the few people who know how to work with their hands instead of phone and computer aps, might finally earn a good living.
Only problem I have with this vid is that the slack of the band is on the wrong side for it to be turning the generator. Looks like the motor is turning the flywheel. I know this motor works, but I can't see this well. I'd like to see it run without the band on it while spinning it.
looks are deceiving. The posted video is: Stirling Runs Window Motor if anyone is interested or if you just want to see another clip of the engine running.
Nice looking project. I'd like to make one for my desk! I'm an accomplished machinist and designer - any chance you'd be willing to sell your engineering drawings?
Hello. I'm not sure I can do that. The project was originally a kit with raw stock and drawings. I modified the design quit a bit but it still might be a issue with my friends at TheLittleMachineShop. If you search that you can find their site and get the plans alone I believe. You probably would have a problem with my drawings anyway. Their just a worksheet with everything converted from metric to English and set up the way I like to work.
Very difficult these days unless you find a machining institute or enter an apprenticeship program. I'm sure you can find some online tutorials if you look but hands on experience could be a problem these days. If I think of something I'll let you know. Maybe I should make some videos.
Hello. I have a 9" South Bend lathe that is somewhere around 60 or 70 years old. There's a picture of it on my video Brushless Motor Construction. My milling machine is a Little bench mill. Grizzly's g-0619 if I remember right.
Man, this is beautiful! Have you considered selling them? If so, where do I sign? I've made (incredibly inefficient) Sterling Engines with tin cans, but never anything that ran as well as this. I simply don't have access or the know-how to machine the parts, and would love to buy one like this!
Hello, I could never make anything for sale. I just spend way to much time trying to get the best possible performance. You are right, it's real hard to get efficiency. Friction is your worst enemy. Balance, bearings and piston tolerance also play a big part. Wish I could accommodate you, but not at this time.
Hi Luke. I use Trinity oil for R/C race cars. Another good choice is Mystery Oil from an auto parts store. A special use choice is a few drops of Trinity in an ounce of industrial cleaner. This would be like contact cleaner. When the cleaner evaporates it leaves a very tiny amount of oil in the bearings. This way the oil will not draw dust or contamination into the bearing, as well as leaving a coating that won't drag.
did you ever think about hooking one of these up to the radiator on a car? it would be nice to find someone making suitable units... quite handy for charging a second battery to run a hydrogen generator....
Belive it or not Free energy is real,But the big oil corporations don't want that technology revealed,Get a REAL working magnet motor at LT-MAGNET-MOTORdotCOM ,Be part of the revolution!
I could be entirely wrong about this but I think the English have submarine with an auxiliary Stirling Engine that when in use makes the submarine stealth because it has no emissions. So is the technology being used by the governments but not made available in a way to help the people who really need it?
@DadHav hi sir, i am working on experiments to use this engine for power generation. I need a piston cylinder set which is durable and low friction..... will little machine shop cut for me what i need or can i get of the shelf? i need a 3/4 inch power piston plus the cylinder for it. currently i have this graphite glass set but the graphite looks too fragile ... my experiment is to add helium and make it more efficient
@DadHav oh thats a great idea because steel has a low friction too , but do they sell the stainless steel pistons off the shelf so i wouldn't have to hassle with machining? another option is to grab a pipe and fill it up with this epoxy putty which later dries to shape but i don't know how precise this is compared to machining. what do you suggest? basically we are after the tightest fit and lowest friction but un-lubricated because oils can cause explosion inside the pressurized chamber.
OK Shorty. That gives me another idea. Do a search for OnlineMetals. This place sells a variety of materials and specializes in low quantity orders. They will have seamless stainless steel tubing in a large variety of outside diameters and wall thickness. You should be able to find what you need. If you us this for both the sleeve and piston I would suggest you use the two different hardness' so not to gall or freeze up. This may be a little expensive in larger size stock.
@OgeronimonominoregO I couldn't agree with you more. I actually contacted infinia regarding purchasing one of their dishes for use at a Christian Youth camp, and the bottom line was they aren't interested in anything less than very large scale deployments.. total bummer. As for use in Subs, they've actually been used for quite some time in Naval subs some with their own oxygen supply for the heat source to extend underwater time from days to weeks.. It would be great to develop something larger
@ DadHav After watching the complete video.. I've got to say, this is probably the finest example of 'home made' Stirling engine that I've seen!! Very well done! Great attention to details and I really like the offset idea. Would be great to get a bunch of like minded folks together to design, test and create a 5kW+ Stirling engine.. in Open Source fashion.. with each persons contribution bettering the overall design... anyone interested ??
@passani1 i have been into this for long time... i have an idea to be able to trap helium inside the engine to make it more efficient... i made plans and i want to put it to action but i been struggling to get the right parts. my idea also eliminates the need for a heat exchanger on the hot side because i direct the sunlight right into the chamber through glass and capture the heat using low emissivity selective surface . currently i am trying to find a suitable power piston cylinder set
Shorty. There might be something to try. Maybe you could find an old used model airplane engine. These can have pistons and sleeves about the size you where talking about. Good luck and let me know you make out.
I very much appreciate the quality workmanship presented here. Having built a stirling myself, I fully understand the level of achievement displayed in your video. I've seen so many YouTube videos for stirling engines, but this one really stands out.
Well for air power tools it probably wouldn't keep up the demand BUT!!! for an air conditioner compressor it might be ideal for the demand and relative small size compressor needed for air conditioning. my thoughts on this are to solely run the compressor so the system only needs a fan powered by the house curren to produce air flow, And mabe for a refrigerator also, some don't require a fan!!!!!.
Are these engine's strong enough to drive an air compressor, if so can the heat developed from the compressor help/ or drive the stirling engine, compressors develop a lot of heat and in some cases boil water. I have seen video's of a 5hp stirling engine on this site,and with this, it may be possible.
@DadHav The engine might not drive a compressor, but could it drive another engine just like itself? For some reason, I think if you turn a stirling engine the 'wrong' way, it gets cold on the end. Is this true? If so, could you create two engines, run one with the burner outside and make the other get frosty inside a cooler or something?
@curtbarile actualy it might if you hook it up to a battery with an inverter! the compressor does not run all the time, only when its filling the tank so it may recharge the battery when its full.,
I guess it depends on how you use the compressor,in other words you whould have to let it fill up and still wait till the battery is full . You'd need to give it a push to get it started,unless you add a small dc motor as a starter and first fill your tank on a full battery! just a taught! :)
@tajtej08 The engine is a re-designed kit. It's available from TheLittleMachineShop. You can do a search for that to find a kit, machined parts, finished model or instructions. I have a few weeks work in design and machining.
Hello, Great idea! I tried it and it worked. It's also a nice way to demonstrate the engine without building a fire under it. I think a change in the pulley diameters could result in the generator charging the starting battery as well. Thanks. This is what the comment section is really good for at times.
I arlready make a stirling engine similarly to your. But somehow it not working, even I use high temperature source. Could you please give me some advises?
If possible, I can send the model designing in Solidwork so that you will figure out it?
@TAIVE16 I believe since there are separate power and displacer pistons in separate cylinders that it would be a gamma type engine. Thanks for visiting. Check out some of my other videos.
John - Your an excellent machinist! Using graphite pistons is a great choice. I like the piston offsets allowing linkages to be linear and the bearings add a nice touch.
Very nice, I know you said that you do CAD in the video, did you also machine these parts as well, if so, nicely done. Not sure why you want to anodize the ID of the cylinders though. I do machining and CAD for a Aerospace Engineering Firm and would love to pick you brain on a professoinal level, have some Ideas that might help with your design.
@intj123 The engine is a kit which consists of the raw materials and the drawings. I changed the design a little and added bearings. Every part was basically machined from solid stock.
If you were to look more into the flywheel as a generator, how big could you get the radius of the flywheel with such low torque? I guess the inertia of the flywheel helps. I have been looking into generator/alternators and want to combine them with this and add a solar heat source. What was the temp of your heat? 1600-2000 rpm is a nice speed for a generator/alternator.
Jim. Yes somewhere down the line I plan on making a flywheel that is actually an axial flux generator. This might be as efficient as I hope to get with the low power the motor puts out.
@DadHav ... Have you made any progress with the axial flux alternator-flywheel, I'm quite interested in seeing those results. Beautiful engine, form and function!
This type motor has very little torque. You must remember it runs by heating and cooling of the same air that in the engine over and over. There is no intake and exhaust. The generator is only a novelty add on. The flag draws about 20 ma. Therefore the motor during the demo is producing only a fraction of a watt. The entire model is a book shelf conversation piece and not intended to be an efficient way to generate electricity.
Sorry Tim, I have no CNC controls. My goal is to keep interest in manual machining in any little way I can. I usually don't have time to make the parts I need for myself.
I also build Sterlings and others but have a hard time finding bearings. Where do you get your open cage miniature bearings. Great work on this engine. Isn't it satisfying when you see it run for the first time? Have a good day.

thats some very high quality work sir . i run a family engineering work shop in scotland with my father and i sure do appreciate some fine quality workman ship. tool making seems to be a dying breed over here but im still flying the flag for our fellow engineers lol , hopefully one day we will be in a position to help other young people to learn the trade . out of interest what machines do you use to craft your master pieces ? im a sucka for machines lol

Hello, It's nice to have something in common with you guys. We have the same problem here. I'm afraid we've seen the last of the Master Tool & Die Makers, at least as we know them and their skills.
My machinery is really only hobby size. I have a Grizzly G-0619 (S-3) Bench milling machine and an old 1940's 9" South Bend lathe. It's even flat belt drive. I just posted a video showing some machining on a Mag Lev Fixture. Have a look. Thanks for the compliment.
Good Luck

Only problem I have with this vid is that the slack of the band is on the wrong side for it to be turning the generator. Looks like the motor is turning the flywheel. I know this motor works, but I can't see this well. I'd like to see it run without the band on it while spinning it.

Hello. I'm not sure I can do that. The project was originally a kit with raw stock and drawings. I modified the design quit a bit but it still might be a issue with my friends at TheLittleMachineShop. If you search that you can find their site and get the plans alone I believe. You probably would have a problem with my drawings anyway. Their just a worksheet with everything converted from metric to English and set up the way I like to work.

Hello, I could never make anything for sale. I just spend way to much time trying to get the best possible performance. You are right, it's real hard to get efficiency. Friction is your worst enemy.

TheLuke2reeve 1 year ago
@TheLuke2reeve
Hi Luke. I use Trinity oil for R/C race cars. Another good choice is Mystery Oil from an auto parts store. A special use choice is a few drops of Trinity in an ounce of industrial cleaner. This would be like contact cleaner. When the cleaner evaporates it leaves a very tiny amount of oil in the bearings. This way the oil will not draw dust or contamination into the bearing, as well as leaving a coating that won't drag.
Take Care.

A company called Infinia is one of several who developed
Stirling technology to output up to 25 KW per unit when
receiving the concentrated sunlight off of large mirrored
dishes.
This is an amazing technology. I hate to see it owned by
the big corporations doing utility scale projects only. It would
be great if some of the gifted enthusiasts on YT could
learn from them and come up with a solid 2-3 KW design
for solar thermal. I think it would be huge and really open
up solar for everyone.
OgeronimonominoregO 1 year ago
@OgeronimonominoregO
I could be entirely wrong about this but I think the English have submarine with an auxiliary Stirling Engine that when in use makes the submarine stealth because it has no emissions. So is the technology being used by the governments but not made available in a way to help the people who really need it?

@DadHav hi sir, i am working on experiments to use this engine for power generation. I need a piston cylinder set which is durable and low friction..... will little machine shop cut for me what i need or can i get of the shelf? i need a 3/4 inch power piston plus the cylinder for it. currently i have this graphite glass set but the graphite looks too fragile ... my experiment is to add helium and make it more efficient

Shorty. Recently I switched to a stainless steel piston in a glass sleeve. Yes. You might be able to find a local machinist to give you some help.
John
DadHav 1 year ago
@DadHav oh thats a great idea because steel has a low friction too , but do they sell the stainless steel pistons off the shelf so i wouldn't have to hassle with machining? another option is to grab a pipe and fill it up with this epoxy putty which later dries to shape but i don't know how precise this is compared to machining. what do you suggest? basically we are after the tightest fit and lowest friction but un-lubricated because oils can cause explosion inside the pressurized chamber.
shorty40merza 1 year ago
@shorty40merza
OK Shorty. That gives me another idea. Do a search for OnlineMetals. This place sells a variety of materials and specializes in low quantity orders. They will have seamless stainless steel tubing in a large variety of outside diameters and wall thickness. You should be able to find what you need. If you us this for both the sleeve and piston I would suggest you use the two different hardness' so not to gall or freeze up. This may be a little expensive in larger size stock.
J
DadHav 1 year ago
@OgeronimonominoregO I couldn't agree with you more. I actually contacted infinia regarding purchasing one of their dishes for use at a Christian Youth camp, and the bottom line was they aren't interested in anything less than very large scale deployments.. total bummer. As for use in Subs, they've actually been used for quite some time in Naval subs some with their own oxygen supply for the heat source to extend underwater time from days to weeks.. It would be great to develop something larger
passani1 1 year ago
@ DadHav After watching the complete video.. I've got to say, this is probably the finest example of 'home made' Stirling engine that I've seen!! Very well done! Great attention to details and I really like the offset idea. Would be great to get a bunch of like minded folks together to design, test and create a 5kW+ Stirling engine.. in Open Source fashion.. with each persons contribution bettering the overall design... anyone interested ??
passani1 1 year ago
@passani1 i have been into this for long time... i have an idea to be able to trap helium inside the engine to make it more efficient... i made plans and i want to put it to action but i been struggling to get the right parts. my idea also eliminates the need for a heat exchanger on the hot side because i direct the sunlight right into the chamber through glass and capture the heat using low emissivity selective surface . currently i am trying to find a suitable power piston cylinder set
shorty40merza 1 year ago

Shorty. There might be something to try. Maybe you could find an old used model airplane engine. These can have pistons and sleeves about the size you where talking about. Good luck and let me know you make out.

Well for air power tools it probably wouldn't keep up the demand BUT!!! for an air conditioner compressor it might be ideal for the demand and relative small size compressor needed for air conditioning. my thoughts on this are to solely run the compressor so the system only needs a fan powered by the house curren to produce air flow, And mabe for a refrigerator also, some don't require a fan!!!!!.

ppalamara1 1 year ago
Are these engine's strong enough to drive an air compressor, if so can the heat developed from the compressor help/ or drive the stirling engine, compressors develop a lot of heat and in some cases boil water. I have seen video's of a 5hp stirling engine on this site,and with this, it may be possible.
curtbarile 1 year ago
@curtbarile This engine wouldn't drive a compressor not to say there isn't one out there someplace. Interesting idea though.
Jphn
DadHav 1 year ago
@DadHav The engine might not drive a compressor, but could it drive another engine just like itself? For some reason, I think if you turn a stirling engine the 'wrong' way, it gets cold on the end. Is this true? If so, could you create two engines, run one with the burner outside and make the other get frosty inside a cooler or something?
MotesTV 1 year ago
@curtbarile actualy it might if you hook it up to a battery with an inverter! the compressor does not run all the time, only when its filling the tank so it may recharge the battery when its full.,
I guess it depends on how you use the compressor,in other words you whould have to let it fill up and still wait till the battery is full . You'd need to give it a push to get it started,unless you add a small dc motor as a starter and first fill your tank on a full battery! just a taught! :)

If you were to look more into the flywheel as a generator, how big could you get the radius of the flywheel with such low torque? I guess the inertia of the flywheel helps. I have been looking into generator/alternators and want to combine them with this and add a solar heat source. What was the temp of your heat? 1600-2000 rpm is a nice speed for a generator/alternator.

@eqtworld
This type motor has very little torque. You must remember it runs by heating and cooling of the same air that in the engine over and over. There is no intake and exhaust. The generator is only a novelty add on. The flag draws about 20 ma. Therefore the motor during the demo is producing only a fraction of a watt. The entire model is a book shelf conversation piece and not intended to be an efficient way to generate electricity.
