Huge Stirling hot air engine II

Cleaned up, slight timing adjustment and smallest Bix gas burner (I use this for my smallest steam engines, happily working).

[@daveboyt6810]

Beautiful work. Anything that can run on that small flame is amazing.

[@robdawkins]

It just gently ticks away, no fuss. I'm always amazed by how little heat is needed.

[@Rob.P]

🙂 It's a very well made engine. It was great to watch this video 👍

[@RustyInventions-wz6ir]

Very nice. Just found your channel and subscribed

[@robdawkins]

Welcome aboard and enjoy the ride...

[@nvmcrider8475]

Wow, a lot of critics and experts in the comments. I say this is super cool, perhaps you could do a video on the design and how you built it.

[@robdawkins]

Hi, I bought this off eBay, cost me 14.50! I just love its slow easy action from a minimal heat source. One of 9 Stirlings. So can't help with plans, sorry!

[@motoresesistemasautomatos.]

Olá, amigo. Parabéns pelo motor! Esse termo-sifão ficou ótimo. Gostaria de saber sobre essa bucha do pistao quente; de qual naterial é feita? Patece polietileno! Obrigado

[@mickowens9839]

Imagine running something like this with a rocket stove set up, 2 pistons, electric motor and a lithium battery. You could power a house with a bundle of twigs... maybe ??

[@davidmclean5067]

Very nice!

[@fredrichenning1367]

What does the water column do? I have not seen a Stirling that uses water??

[@robdawkins]

Hi, there is a water jacket that surrounds the "cool" piston. The water circulated in at top of copper tube. After 20 minutes run, the water is near boiling...

I saw a really hudge one in a waterworks museum in England.... somwhere near Leominster. Still working on live stream days

[@Sdnaurs]

That'd be Hereford Waterworks Museum - I'm a few miles nearby.

[@johnp3937]

@@Sdnaurs that's right. I remember now. I flew into a small airfield where they were doing helicopter training and made a hash of the circuit. Had to go to the control tower and get told off...

[@DrBretPalmer]

Hi Rob, I think this is a fantastic engine. I would like to know how you built your cylinders and pistons please? Did you get them from something else or make them? I only as as I am building my own sterling engine but having difficulty building the pistons. Take care and hope to hear from you soon. Kind regards Bret

​@@robdawkins No you didn't.

[@eifionjones559]

It is going nice, low power in these engines anyway and you could always put a belt on the flywheel

[@robdawkins]

It just puts a smile on my face, it will happily tick away for an hour. My philosophy if you it gives you joy, perfect.

[@eifionjones559]

@@robdawkins I am with you , my philosophy too

Puts a 😊 on my face.....

[@ApartmentPrepping]

Did you build this? Care to post a video tutorial?

[@biffaozzie2373]

Funny definition of “huge”!

[@robdawkins]

Compared to my other Stirlings, its huge. 😉

[@robert-oq9jq]

Been researching this for a while and from what I've gathered they'd have zero torque you could put your pinky finger on a big one and bring it to a halt very neat and interesting but basically useless for anything requiring more torque than a fan, haven't seen anyone successfully power a generator with one yet

[@robdawkins]

Hi Robert, you are spot on with this beast...

[@robert-oq9jq]

Thank you, but I wish I wasn't, could eliminate Steam from the equation, have you read about the steamless Freon condensing engine? to me that was the answer, but the rights to it was bought and they buried that one deep@@robdawkins

[@lemagicbaguette1917]

I've seen that most Stirlings run on one atm of pressure. How high do you think we can take the pressure and, therefore, torque before it breaks? As far as I can tell, the cylinders are closed, which might make it possible to overpressure it irrelative to the sky.

[@BowenOrg]

DEAR MR. DAWKINS.... CAN YOU "PLEASE" EXPLAIN HOW THIS WORKS!!! : ) Most appreciated. Amen Retired, Veteran

[@robdawkins]

I hope this helps: A Stirling engine has a sealed cylinder with one part hot and the other cold. The working air inside the engine is moved by a mechanism from the hot side to the cold side. When the air is on the hot side it expands and pushes up on a piston. When it moves back to the cold side it contracts.

[@BowenOrg]

HUGE is hardly what i would call this thing ???

[@bussi7859]

Not huge, this crap is tiny and makes nothing but sound

[@bussi7859]

A useless toy

[@FreemonSandlewould]

That's just a toy.

[@daviddavids2884]

information. poorly designed. NO output shaft. TOO slow. in part, because of the over-long hot-side stroke length.! a thermosiphon-based cooling system in which the reservoir is not optimal located; eg., fully 'above' the hot process. a Well-designed heat engine needs no supplemental cooling. cheers

[@ВикторЗакомолдин-в8ж]

Too slow and underpowered.
