Self-made stirling engine video

[StirlingEngine123]

Interesting homemade engine! Congratulations! ( I notice I always start my comments with this senteces... but no problem... people like!!!! lol) How much power did it produces? Wath's the power piston made of? Tkx. Good work!

[tsbrownie]

Interesting.  Would like to know how this one works. (There are many designs).

[quafka]

@tsbrownie: Sorry, I can't recall the name of the design, but it's very basic type. This one has the same idea: pmdbnBCo7q0

[EVZebra]

Well done - great job

[fuge90]

Are these engines easy to build from other parts

[quafka]

@fuge90: It's hard to say how "easy" it is to build this engine. Depends on the experience, tools and parts you have available.

[piespokladowy]

great!

[siviili2003]

Saiskos udella minkä moottorin sylinteri/mäntä tuossa pienemmällä puolen liikkuu.

Ehkä aion rakentaa samankaltaisen koe stirlingin joskus.

Boring

[bazengao]

dear god its true the transformer do exist!! and they can take to shape of a striling engine!!

[douro20]

The chimney is a nice touch.

[BackwardProduction]

nice job man.

[magicalmachines]

Hey if anyone is interested in finding out more about how this engine works check out my site :)

[OttomanDrifter91]

what is your site adress? -.-

[bimblinghill]

Cool! A friend is building a small Stirling. It will sit on his wood burning stove and drive a small fan. The fan will help to circulate the warm air which will improve the effectiveness of his stove in warming his house. So, only very small output (1-2W), but useful work!

[deauzie]

could you intergrate it into a stove to cook on ?

is it the most efficent sterling engine design ?

Could you silence it ?

Could it produce enough power to run a radio and 2 low voltage lights ?

[quafka]

Well yes, you basicly could integrate it into a stove. This isn't the most efficent type of stirling engine, for example preassured and engines with bigger heating-area, are more efficent. The engine is quite silent already. And about the radio and lights: hardly, the engine producess arround few wats.

[firedude201234]

@quafka

it could certainly run a radio and some small flashlight bulbs but not much more..... granted im not the builder but yeah you could easily do that quafka ;D

[rsullica]

Hey Quafka

Quit an engine there. It looks like it has good power for it's size. There is a lot of torque power in that flywheel. I am wanting to build a usable engine also. You mention plans in other posts below. How might I get a look at them? Thanks, and keep having fun!

[tomek123kotek]

so the video made itself

[smartstuff2buy]

no stupid, the engine built itself

[tomek123kotek]

oooohhhh the engine built itself but hows that possible. another strilling engine helped it????

[smartstuff2buy]

if i told u how a sterling engine built another sterling engine i would have to zap u with the memory eraser and u dont want that,its top secret

[MilanKarakas]

@tomek123kotek

Oh, no. It is just poor translation. I tried google translate to my language, and got something like: "I made it myself, without help of anyone else". Or DIY (Do It Yourself). Or 'home-built' (this not means that machine is built by your home - but 'in' your home (by you), or more precisely - in your garage. :-)

[tomek123kotek]

@MilanKarakas You know I was just mocking the poorly written title.

[MilanKarakas]

@tomek123kotek Yes. That is fine if you looking for entertainment on youtube. I am looking for practical idea, practical solution of the problem that I can't solve myself - mostly about Stirling engines. And, exactly here on youtube I found many answers, no matter how good or bad grammar is.

For example: how to make piston that fit perfectly into cylinder, yet maintain proper (incredible small) gap between that two?

The answer is: no gap at all - ferrofluid and magnetic piston.

[mechtech2004]

You need to reveal the heat source, looks like you are using compressed air, and also show this device under some kind of useful work load. I'm tired of watching too many of these alternative energy device videos shown here not performing any work load, which makes them very doubtful they will perform under any type of load at all! To coin a phrase "You can fool Some of the people Some of the time, but you can't fool All of the people All of the time!"

[knightspy]

which makes them very doubtful they will perform under any type of load at all!-they were in heavy use during the industrial revolution in the 19 century they were safer and cheaper than steam boilers

[quafka]

The heat source is regular firewood, you can see some in the ground. Check the drawings (on your right) and google, if you have doubts about the stirling-engines in general.

Power of this engine is very loow, arround few wats. So there isn't much of point to place it under a workload. It was build just fr fun. And watchin it run - that's also fun.

[shorty40merza]

@quafka  yes true your wood fireplace is probably emitting at least 10 kilowatts and then you only get few watts out , its very bad efficiency / i wish they make one with good efficiency ,, i think if i can make one with 10% efficiency i would be celebrating

[Fbiman567]

nice color, looks kinda like a ferrari

[quafka]

.. and performance is pretty much the same.

[buschwacka1]

Quafka, is the cylinder of your nice engine from a deutz of hatz aircooled diesel?

Thanks

[quafka]

Yes, the cylinder and the piston are from Deutz air-cooled diesel tractor. Flywheel was originally in some farming-releated machine, and the connecting rod is self-made.

[30GB]

biggest stirling engine iv ever seen wow and nice work

[lapere71]

Nice ford transit.

[quafka]

Indeed.

[mowerofdoom]

I love this engine. CHUNKY!

[quafka]

Plans added! See the More-section on the upper right.

[gsusman]

is there any chance of you posting the plans for this? Or sharing them by email? I've wanted to make something on this scale for awhile!

[abelimore]

that is a realy great engine you have made a realy good job on that , i am building one my self and your machine is an inspiration to me

[boxa888]

couldnt u put a pipe in your house so that there is a dfferential between the attic which is usually hot and the cellar which is usually really cold. this deffertial could probbably run something right. i think i might try it. i said this because tesla wanted to make engines that take high potential and bring it to low ,making power something like that .

[441rider]

That is pushing a lot of weight just in structure. The crank is great! heavy duty! An alloy roller bearing machined type should fly ad 5 freznel lenses who knows. A mechanical sun tracker could be awesome Rube G challenge. Great job, maybe a pond pump LOL!

[boxa888]

yea u probably could build a mechanical sun tracker by using heat pressures on its angles to open valves, something like that using like high pressure for sun side and cold for side without sun turning it . these things are really neat.

[bradmacaroon]

Can i get some prints, parts list etc to duplicate this? thanks. Nice vid and machine

[pimpachu]

That's a very well made, smooth running beast. What do you plan to use it for? You could power a lathe or other shop equipment with it, no doubt.

[quafka]

I don't have any particular use for it.. I just wanted to build it, and see if I can get it to spin. It was a lot of fun.

[ducttaperulestheworl]

is it fire powered?

[19marco82]

Nice

[honestjohnnfld]

Approximately what is the hot end temperature? And how many Watts are you getting from it?

Archibald

Northfield, Minnesota

[quafka]

The temperature is the same what the wood, burning in there, gives - arround the temperature of a stove. I think it gives something arround 50 watts... very low. Haven't measured it though.

[honestjohnnfld]

It would be very interesting to know how much power is produced.

Can you rig up a Prony brake to it?

Archibald

[quafka]

Sorry, I don't have the equipment. I agree, would be interesting. But as I build this for fun, so far it's been enough just to see it working .. even if the ammount of power it produces isn't anything significant.

[honestjohnnfld]

An easy way to get a good horsepower number is to have it pump water up a hill. See how many gallons per minute it pumps and how far above the pump it is pumped.

If you give me those numbers, I can calculate the power. I like your engine and am trying to help you. Do you have any drawings or sketches you could send me of it?

[offgrid2010]

He's doing it for fun. He's not asking for help....Sterling engines do not have much torque at atmospheric pressure. To do useful work - not just for fun - as many others say they want to do - perhaps this design could be modified to work with enclosed cylinders. Also instead of air - a fluid or gas such as hydrogen would be neccessary.

[quafka]

Well, I wouldn't put hydrogen in there. Enclosed cylinders are better, but they take more time & money to build.

[jjmqwerty]

@quafka the highest pressure engines use hydrogen at high pressure because of its thermal properties but the systems are sealed and do not allow oxygen inside. years ago one large engine blew up because oil got inside the cylinders.
