Very good, I know it is an engine of small power, for its size, but very interesting, congratulations to those who have been engaged in the construction of this engine, which I imagine the great labor involved in this project. Greetings from Brazil, Leandro Wagner.
Great job this is one of the best Stirling engines I've seen insurance would have much to learn from the person who built it is here where you see the experience acquired over the years congratulations!!!!
@@Leonelf0 Delve has a point. You never see video of them on RUclips. I'm trying to find info on the ones that power submarines (lotsa power there) but the military don't want to share.
One of the best, IMO, properties of the Stirling engine is it's fuel agnosticism; wood, coal, gasoline, propane, solar, electricity, hydrogen, literal garbage... Anything that can generate enough heat is potential fuel for a Stirling engine. Now if only they were more power efficient lol. An electric or gas motor that size would be massive overkill for such a small vehicle, but this thing barely putts around the yard
Awesome work. Would love to see a stationary version driving a dual disc permanent magnet axial flux 3 phase alternator. Every remote village in the world could use one, or six, or 20.
im going off grid and am desiging a fresnel-enhanced, geothermally cooled stirling eng-gen. thanks for the suggestion to use that specific type of alternator.
@@pottasium7117 NASA and some collage teamed up and converted a truck engine into a Stirling in the late 70's early 80's and used it in a maintenance truck at military bases for a year running it off of whatever fuel was around. It got 45% better fuel economy over the same power internal combustion engine. I forgot how many thousands of miles they put on it in that year but it didn't even need an oil change because without the usual blowby contamination you get from an internal combustion engine, the oil was like new. They even drove it from like Louisiana to D.C. averaging 50mph. Thats pretty good considering interstates were few and far between back then.
I'm always surprised at how noisy these things are. Used to thing internal combustion engines were noisy because of the explosive nature of their operation.
now thats passionate can you imagine the hours spent on that thing??. there is so little torque to these engines that they have to be carfully chosen for use . like a water pump the water cows on a range would be an ideal situation
Impressive home-built engine! Always fun to see one run. Too bad it barely moves the tractor. Nice try. But it only underscores the impracticality of the Stirling engine.
Impressive. I'm thinking a better fire and that motor would have power. rocket stove perhaps? Or forge style? Should gear that fan up a ways too. Probably better air cooled, I'd think. Your trying to cool to within 5 Deg. of air temp so it has to be pretty direct. That motor could easily be put to many uses, and it's still small.
Ever seen a steam plough? You park two steam traction engines either end of a field and use winches to pull a plough from one to the other. It was a 'popular' solution for a while. Internal combustion is much better at that sort of thing. Think about the tractor in the video as a proof of concept - essentially it's an alternate form of steam traction engine, but a tiny one. It just needs scaling up. And having an engine that moves is a lot more fun than one that doesn't.
@@pd4165 I think there is an excess of form over content here. too much of this iron. It should be a simple construction with a large diameter working piston.
Very ingenious and a beautiful engine, but as I understand it the purpose of a tractor is to exert traction. This contraption bogs down under it's own weight, I don't think it would even be able to pull a trailer, let alone drive any field implements. The power to weight ratio of stirling engines makes them generally unsuitable for mobile applications. Even if it made enough horsepower to be useful, it would burn through a lot of wood and you would need to constantly stoke the fire and clear ashes from the fire box. You would be better off doing the work by hand or with a draught animal, and saving the wood for your stove. That's how I see it, anyway. As a show piece its awesome though.
Mark McCormack, there are some things in life that one does for no other purpose than just enjoying doing it and giving pleasure to other people who are interested in the invisible and silent functions of our universe. There is a lot going on in that tractor that interests researchers and just people who like the beauty and harmony processes rather than some other form of entertainment. It is a pity that many of our schools just do not appreciate that there are people who find interest in the beauty of invisible and silent functions of which the universe is full of and yet many schools are not aware of such natural functions and they transfer to the children what has been written or sung in the past. There is such beauty in that puffing functions that and one needs to dig deep, very deep to try and understand them and improve them.
@spikedpsycho Desalination plants are often in arid areas - arid areas tend not to be cloudy (otherwise it'd rain) which means lots of sunshine...and in useful amounts in the tropics. Collecting the sunshine can use up a lot of space - but as long as Sterling power is more efficient (large plant could be damn efficient) than PV then we could stop wasting hydrocarbons on desalination. As for Mark McC rubbishing Sterling as motive power - I'm here looking for leads/contacts for a potential installation. I'm seriously considering moving onto a narrow boat (a vessel designed for the peculiarities of the British canal system - the locks are about 2.2M wide and 25M long). The traditional solution is a put-put diesel (about 20hp IIRC) but whenever I've driven one there was plenty of excess power - a residential boat being much lighter than a commercial carrier. So a Stirling would be a good candidate for a CHP system (and a bank of batteries could assist if you need a bit more acceleration - turning a long boat on a narrow canal means resorting to special turning places called 'winding holes' - they would use ropes to control the boat while the wind, there's usually some kind of breeze in the UK, pushes on the flat side of the barge. It's much faster/more convenient with power). One thing that struck me about Stirling powered boats was that the hot end was frequently at the top. If you built an insulated box around the hot cylinder/s and packed it with charcoal/wood pellets that would (ho-ho) seem to be a good heat source - and if you're driving the boat there's plenty of time to fiddle with the combustion process, it's not exactly high tempo. Walkers can overtake you.
Modern Sterling engines like the Free-Piston Sterling Engine (FPSE) can run on any fuel source, including clean-burning natural gas. Furthermore, they can generate electricity as well as heat, so you can basically have Tesla-like performance on your tractor (plenty of torque) while also providing heating for your electronics, batteries, etc. when you need it.
Clear evidence that the Stirling engine is ill suited for transport. It is far better used as a stationary engine or, in any application where slow and steady RPMs are required.
Brilliant! Really enjoy watching this old tek. In my opinion this is still pure engineering!
Still pure engineering, it's no less impressive now as it where back then it's the same engineering;)
One of the rare times I’ve seen a sterling engine that produced enough power to do work
Unfortunately it can hardly put it self in motion even on flat ground with no plow in sight.
In Sweden our Gotland class submarines are driven by stirling engines..

Great works, Stirling engine still amazes me.
things like this could power your house

No better Knowledge then old Knowledge . Hats of to you Sir i enjoyed this very much .
Those engines work great when there is a need for heat and power :)
With the exemption of NASA you have the largest, Most powerful Sterling on RUclips. That's bragging rights right there! Congratulations
afaik there are also some 10kW generators for parabolic mirrors,
@@Leonelf0 Delve has a point. You never see video of them on RUclips.

Qnergy and Sunpower have got this guy beat. Free-piston > kinematic in terms of performance and reliability.
Молодец Дед , не поленился сделать трактор на Стирлинге.
A very nice machine!
These are good for generating power, from on top of a woodstove. Safe quite and destroy wind and solar, for reliability
I dig his style.

Wow, that is cool!
so cool! how much HP could it provide?
Brilliant! At least it will keep his feet warm in Winter. An a great cure for arthritis too.
Amazing! The tractor is so fast!
congratulation nice work you got there....
pure art...
Awsome! Vrey good! How much HP? Congratulations.
Id guess less than 5 hp
this is fascinating. Could one of theese, but upscaled be teoretically used in an automobile?
No, not in a meaningful way sadly.
fair enough, probably would weigh too much
Large, heavy, very low power, low maximum RPM and slow to maneuver.

why are their exhaust pipes sir? doesn't a stirling engine only use heated air?

Nice
great !!!!
Super cool
Хорошо с горочки пошёл!

Bravo...
Does it have enough torque to get any work done?
Дедушка молодец ! Правда моторчик шумит слабый и шумит сильно, пердячего пара не хватает .

Quite amazing that he made this, but impractical LOL. Only serves as a fun machine to drive around.
Increiblemente funciona!
very Awsome
Hi, I’m George from Exxon. Would like to buy your tractor.
What is the radiator for?
the stirling engine is water-cooled.
Cool curio, but the field it can not be plowed

If earth only have million people , this machine good for co2 production to give those trees more glass house gas to grow up
imagine if the wood stove were a rocket stove
smart man
Needs a flywheel!
he made a boat engine too
about 1KW

Well Mark when you make anything fueled on wood that moves like I have then you may have something to say.

bellissimo, peccato che i motori stirling abbiano poca potenza.
È lo stesso della potenza del vapore. Troppo pesante.
ну дед даёт пару :)
Я думал деду приедется толкать до дома трактор
Не скоро едет(...
could burn cow chips
Этот двигатель не тянет
Big Oil is not going to like this
+betamale3 but Big Wood for sure would
why no car with stirling?
