Big stirling engine on wood stove

[vaneztax]

Good demo but the engine doesn't perform any work. I would attach a dynamo to generate electricity.

[lmojzis92]

You could use the stirling engine to pump air to the stove... :)

[yerstalwartpro]

Hey, arctic non-physicist here - if it's like -40 outside of your cabin, could you use that in any way to increase the temperature differential without cooling the room?

[OftenRatherAmused]

@yerstalwartpro Thermodynamically speaking, no, but seeing as you're adding heat to the room anyways I don't think using the outside cold as your sink would lower temperatures noticeably at all if you did it well. Maybe you could make up for an inefficiency the house already has such as using a poorly insulated cold wall or entryway as your heat sink for regenerative warming of the house. Just be careful you don't just stick one end in the wall, you may present a fire hazard! :)

[Naghelfar1]

you should make a .pdf file with some plans! this is one of the greater ones i have seen on the net. Cheers

[Dabeweegthiere]

I am looking to buy one of these but i can't find a shop where they sell 'big' ones , only toy demonstration models ..Anybody got an idea where to find it ? Or find plans to make one yaarseelf ? Im only looking for models this size or biggers , so it can have some tools hooked up to.

Thanks in advance .

[grasswine]

This is soo great. Thanks.

[crapthisisalongusern]

Impressive, gas powered?

[IndianolaStirling]

Hi there, I was curiousif you used a simple annular heat exchanger on the hot end or something finned or tubes. Also it sounded like the hot cap was not directly in the fire and I was wondering if you found the heating to be sufficient? Thanks for your time. Also curious if you've put it on a brake to get any power numbers?

[piespokladowy]

Super!

[r43007]

can  you sale?

[24max]

@r43007 yes I can, 3000€. but there is much to do to get reliable power out of it.

[WatchingforTruthLORD]

How many usable watts can you get a high end with high heat wood? How much more investment and knoweledge would it take to invert to my home or is it wirth it? Also could power with solar magnafaction when not cloudy? and ideas? Thanks Blessings to you and your family

[xaramano]

Put a fun to spread the heat in the room

[TheCottonTop]

I like turtles.

[leparditas]

nice application

[ciabrenn]

how do I build one, where do I get plans????

[24max]

@ciabrenn Sorry, plans are only in my thick head. Not goodenough to copy yet.

[jjmqwerty]

this has to be one of the best running hot air engines on the net.. andrew ross built a stove top engine twenty years ago but i think this one runs faster

[24max]

@jjmqwerty Thanks, but I think that Ross engines are far better than mine and

there are better ones on the net.

[grizz2225]

What application did you plan to use this for? Looks like it'd have enough power to pump your well or run a small gen.

[SWINGREGORY]

trop petit pour produire de l électricité

mais il y a de l'idée

[fernandesilyt]

Do you know the power of your engine?

[24max]

Sorry but I'm not living near my cottage anymore and my time is limited so it might take some time untill I get something done.

[firewoodguy2009]

id like to see you make a fire and than fill up the wood stove with logs

for a very hot long burn

make the stove cherry red

[sammorgan3]

Funny that I never see much active cooling of the cold side on stirlings... Larger temperature differential = more power.

[Lollocide]

Yeah, but then you need to actively cool the cold side which needs power, which actually means more work for small gains.

[brianwesley28]

@Lollocide

Depends upon the method of active cooling in regard to any ancillary losses, or amount of gain achieved by cooling. More work, as in engineering and construction, perhaps.

[NOBOX7]

@Lollocide i agree with u the power needed to circulate fluid isnt worth it,, these motors cant afford sacrficial losses ,

[nibed123]

@sammorgan3 What i was planning to do is to put hot side of engine in my stove and the cold one, outside the house.... What do you think about that?

[GroovyGuitar02]

@sammorgan3 yeah but i think ice + hot stove = iron breaking , and if not , at least , rust .

[zker666]

how many rpm does that generate?

[fernandesilyt]

Is it a alpha or gamma stirling?

[24max]

alpha

[firewoodguy2009]

what

[Toroer]

I find lots of stirling videos on youtube. Almost all of them are freewheeling, which means they generate only enough power to fight the friction. I wonder how much power can this one produce if you were to hook it up to some sort of a generator...

[24max]

Please, read the older answers before making new questions...

[Toroer]

I made a comment rather then asking you a question.

[firewoodguy2009]

what

[HebinhoTdF]

Without knowing the exact dimensions, I would guess that this machines can deliver a mechanical power between 100 and 150 Watts.

Disenco (UK) is working on a "HomePowerPlant" using a beta type stirling engine, which will be able to provide 3 kW of electric and approx. 12 kW of thermal power.

[butkatrello]

That fly wheel looks like it came off an exercise bike. Do you have another fan as a blower? Like a forge, if you add the air to the fire you won't get much smoke..

Nice n quiet that one is..

[prashantchan1977]

What's the Pressure like? TDC and BDC of the engine?

[24max]

Hi.

If you want to make a simple engine with power, it's gonna be big. I'll try to post some info when I got the time...

[brianwesley28]

Nice. What are the specs of the Stirling? Have you coupled it with a generator? Amps, watts? Very nice house and property, too. There's something about the view of a lake from your backyard.

[24max]

I haven't coupled it with a generator, too little power to do anything usefull yet.

[brianwesley28]

Could I offer a suggestion on obtaining more usable thermal electric potential from the set-up? I understand how the concept of the Stirling Engine works, although I haven't yet constructed one. I have been playing with Peltier Cells, though. They also work on the principle of temperature differentials. If you can get that Stirling turning a generator, regardless of size, the Peltiers can be used to generate additional electrcity. It isn't much, per Peltier, but in number...

[brianwesley28]

The Peltiers will last for something like 20 years of use, as long as they don't get TOO hot, on the hot side, and fry them, or something. They're interesting little devices, t say the least. I've imagined multiple uses for them. Quite versitle. Heat sinking will be important. I'm in the process of constructing something that should be pretty interesting when it is completed. I may post it when it is completed? We'll see. Anyway, I'd be glad to assist you with ideas.

[cowboygcg7]

can you send me the specs for that pleas and thank you if you would

[24max]

Sorry, the plans are only in my head, and I'm not gonna draw them untill the engine is performing better. There is no use to copy this engine yet.

[cowboygcg7]

hi i am doing a science fair on sterling engine and i would like if you could send me the specs for the one u build and tell me how you build it i would be great full if you would please let me know thank you

[jgposner]

This is exactly what I am looking for. I want to generate electricity with our wood stove and a stirling engine. Let me know how you progress. I want to buy one.

[24max]

I'll keep sending these clips when I get something done. I got only this proto so nothing to sell yet...

[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 ?

[24max]

Yes, It could be integrated to stove and cook at the same time. It's alpha desing, I't is

possible to make highly efficient, mine is not yet. I could silence it, there is some gap at the pistons bearings that makes noise. My goal is 500w so radio and lights would then be possible...

[4Mengineering]

just lovely! grand work.

[SWINGREGORY]

THE MUST

GREAT

[edohard]

hi, how many watts can produce it?

[24max]

I haven't measured it yet, not many. I have to make a better stove that I can get the hot cylinder allso in to the fire.

[OleTC]

That is admirable. You are one of the few, that build an everyday usable application of the Stirling principle.

You'll succeed, I'm sure.

It appears to be somewhat noisy in the living room, but the recording might not be precise at that.

[24max]

Thanks! I'll try my best.

[Odziz]

Nice CHP (Combined Heat and Power) set-up!

[24max]

I actually took a shover with that cooling water, stove heated the cottage and engine power is ment to be captured in battery, so not much is lost. But making this all work in everyday life might be tricky...

[zammel777]

Thanks for posting this . What a nice engine:)
