there's a interesting high voltage steam unit that runs on wood .it's Armstrongs portable high voltage steam generator.check it out .a little wood and some water and your running electricity.
some information 3:52 put the wrist pin at the Top, and use a SHORTER piston skirt.!!! a Horizontal orientation Should be used; because of GRAVITY.!!! you may know that in order to use strokes of equal length, the volume/diameter of the hot cylinder needs to be a bit greater-than the cold one. there is no need for supplemental cooling, IF the design of a stirling engine includes Adequate (physical) separation of the sides. a regenerator Should be made of a material that conducts heat Poorly. if wanted, it is easy to build a convective heat trap into a regenerator. a heat engine produces low torque. consequently, efficiency (as a prime mover) will be highest when a heat engine is made to run as fast as possible, and is loaded in such a way that rpms drop by about ten percent of the max un-loaded rpms.
Even 50-100watt would be awesome. it adds up when running 24/7 to top off a large solar battery bank during a few days of rain and heavy clouds. Id really love a small one but all the small ones seem to be under 10watt.
information you ended up with a decent engine. in order to make a better engine, you need to make FEWER design mistakes.!!! 9:42 EVERYTHING that can be done should be done to MINIMIZE the amount of MASS in every component that Reciprocates.! this includes, pistons, displacers, connecting rods. this rule also applies to components that contribute to an out of balance condition; eg., crank pins. those 'piston' tubes SHOULD be ALUMINUM.!!! the duct configuration used NEEDS to be compatible with the engine configuration; either two piston or displacer. a heat engine can operate without added lubricant because, where metal components interact their HARDNESSES are different. (see the STRATEGIC use of different metals 'together'.)
i've just started getting in to stirling engines and am totally fascinated by your last build. I cannot wait to see this new project come together. Please document as much of it as you can, it's inspiring.
I didn't understand everything about the design, but it still seems innovative to me. I particularly like the heat exchangers and the use of a regenerator. I'm not surprised you're excited. Although you are my competition, I wish you success. Regards
If this is your third engine build I'm going to have to look back at your first. I have built 1 Stirling engine for a college project, it was a no weld no machining build from 2 tin cans, a beer can some wire and copper pipe.

Looks great! Just one thought...why only one PTFE gliding element on the piston? Wouldn't having two prevent it from jamming and/or having metal on metal contact?
Hi, the piston has 4 gliding elements at the top radially (probably didn't explain that we'll) and the leather seal section will hopefully take care of the piston bottom
@@ShanePomeroy ahh sounds good 👍🏽 no worries about explaining all the details. There is just too much to cram into a video...will see once you build it anyway! I'm excited!
Very good video. I'm looking at the possibility of a woodburning 2 kw generator. I need 2 kw to power my well pump. A sterling would be great but for now I I've been looking at wood gasification. Good Luck, Rick
An interesting start. Above the hearth, ceramic wool would be better. It is widely used in blast furnaces. It is light, cheap and insulates better than chamotte. (Google translator)
Many thanks. Yes, I think your right. The only problems I've got with wool is the durability and holding it in place. If I could get around these then I'd be on a winner
Hi, Unfortuantly I don't live in a hot part of the world. As an example we're into our second month of rain! I don't think this engine would be efficient enough to be effective. Solar panels are so cheap these days the stirling engine doesn't do well for this purpose from what I've read(unless it's just for fun! : )
This looks really kool, I've queued up the rest of the series for later. What was the thinking behind using stainless for the heat exchanger? My experience with stainless is that it conducts heat very poorly
Hi, I used stainless because it will last a long time and everyone else recommends it. Good point about stainless! It is about 4 times less heat conductive than mild steel! I I am now interested in building another engine with mild steel to see how long it Will last : ) all the best
I just found your Channel! Thank you for this!!! Is there any chance you would consider selling the designs in a build manual! Loving this!!! Thanks you for your efforts!!!
Have you considered secondary air inlets in the rocket stove for greater efficiency and cleaner burn? Most modern wood heaters have them now but I think the best examples are in the gassifying wood stoves sometimes called smokeless fire pits.

8:32 are those con-rods HOLLOW or what.!?!?!? they sureashell don't need to be that robust.!!!
Nice design you have came up with. 1kW would be useful. Are you going to TIG the stainless?
Thanks, I'll see how good it is in a few months when I try it! I may tig it or just mig it
Even 50-100watt would be awesome. it adds up when running 24/7 to top off a large solar battery bank during a few days of rain and heavy clouds. Id really love a small one but all the small ones seem to be under 10watt.
I dunno, that's lots of steel, I see a huge heat sink.
There's one way to find out! build it!

500 watts!!! very conservative estimate ! With a long stroke like that it should be a lot of torque. Beautiful job!

Could you do an experiment for me? It is to use the solar energy to drive the Stirling engine
Cool! I don’t know that I’ve ever seen a Sterling build video this detailed
I didn't understand everything about the design, but it still seems innovative to me. I particularly like the heat exchangers and the use of a regenerator. I'm not surprised you're excited. Although you are my competition, I wish you success. Regards
I am also following your build videos with great interest!

9:19 ??? what is that for.!!! there is no gas exchange, in a heat engine.!
😊replace the flywheel with a hollow one filled with concrete.
I love the way you designed this engine! And I agree with your thoughts about simplicity 😀 Cheers mate
Hopefully only a few more weeks and we're see if it works, cheers

Привет . Желаю,что бы все хорошо получилось . Отлично Все рассказываете , интересно . Стирлинг классика ))
That looks like a fu project. I'd buy a kit if it were available in Canada! Subscribed!
Meant to say *FUN.* Sorry! LOL

Looks fantastic
Wished I could Source all the bits so I can play with one as well
Excited to see how it all goes together
I look forward to following the build. Good luck on your project.
I have an interest in Stirling engines, very keen to see how this ambitious project progresses
3:19 this drawing shows a TWO Piston config and regenerator; not a displacer config.!!!
Yes, this is a Alpha stirling engine.
Very good video. I'm looking at the possibility of a woodburning 2 kw generator. I need 2 kw to power my well pump. A sterling would be great but for now I I've been looking at wood gasification. Good Luck, Rick

@@ShanePomeroy The lower part of the hearth is chamotte. The upper one is ceramic wool, fixed in points as in large stoves.
Shane your back. !!
This is good news.
Higher working pressure maybe helium
You haven't thought about cylinder offset from crankshaft centre?
🤔 no. Do you mean take advantage of the change in stroke velocity? I saw an article about something like that for internal combustion engines
@@ShanePomeroy but on afterthought: It would not make sense with your system of rods & rockers.
Hai where one buy the kit from Im south Africa
Hi, Not for general sale yet. But hopefully will have something available when a few issues are resolved! Cheers
7:34 That's not laser cut, it's flame cut (oxy propane, by the looks of it). Nice idea, making a kit. 👍
Replace the flywheels with axilflux alternators, apparently they have no cogging.
I will look into this, many thanks

Dear Shane very interesting project you've got there, just wondered in ballpark terms what that material cut like that costs?
I'm scared to add it up!
Лайк из уважения, коммент для продвижения!
I just found your Channel! Thank you for this!!! Is there any chance you would consider selling the designs in a build manual!
Loving this!!! Thanks you for your efforts!!!
Hi Jose, many thanks. Yes I would be prepared to produce a manual. I should be a few months finishing this one and checking it works! cheers
That’s going to be excellent! Thank you!
Is a STEP file available for this? I would like to see the CAD. I assume you drew it up.
I'd like to see it working first, cheers
@@ShanePomeroy 🤞

Yes, I can incorporate a secondary burn in, I'll look into it. I'll take a look at those fire pits. many thanks
