- Pressurized alpha stirling engine. Balanced Ross yoke linkage.
This is another attempt for making power producing Stirling engine. This model was made for testing fluid power capability. Design costs: 3 monts for design, 4 weeks for welding and mashining, 300$ for laser cutting all sheets. Engine weight is about 30 kg.
To All stirling fans:
In the project I used an Excel table that can be found at www.sesusa.org/GCS2002.xls . I made the engine in rigid correspondence to the table and I got a calculated power output and RPM. It is a Best Result of the engine, not plans or design. - Věda a technologie
i think this is the only stirling engine video that says the real stuff, the wattage, the efficiency, the heat input, etc...all others are just toys, but this one is a real scientific engine made at home...congratulations and best wishes!
Well, if you look at mine, it runs a portable transistor radio... Doing something useful.
Very well done. You are also one of the few persons who does a proper power test and not just let it spin in idle. Props for the power vs rpm curve
Congratulations! I`ve never imagined that could run with air pressure!!! You give and idea about how to obtain extra power! Congratulations again!
well guys , you just found the way- how to using 3kw heater and stirling engine generate 120 wats.Great job:)
Top of the class for stirling engine builders - well done! I hope your success motivates you to achieving even better results, just as your success motivates us all with an interest in stirling engines! Thanks for sharing your work.
Excelent, Work.
One of the best stirling engines in youtube.
very nice engine! a well crafted machine. bravo
A really good project and very informative, thanks for sharing. :)
Have you tried using HHO Gas fire to heat the element to run the Stirling engine?
I tried only natural gas. You can see it at my other videos.
It is better to use acetylene. High temp and simple to get.
amazing machine, congratulations
awesome build congrats!
I'm an engineer student in his last year of college and man, I must say that this is amazing. I will follow your progress. Best regards from Spain
parabens pelo desenvolvimento do motor....ficou bom.
You don't know how close to Genius you are! Most best insight to generating electricity from sterling engine from a fire source I have seen everywhere on CZcams. I would buy a motor off you when you perfect your works. I want one I can somehow sit close to a burning heat source such as a pot belly stove, wood fire or a common 44 gallon drum with wood burning in it as a rocket burner as they make lots of heat. Than you so much for posting and please time the time to post as much as you can.
Доброго время суток. Скажите пожалуйста. Двигатель сам себя пока не нагревает? Какой мощности стоит лампочка на подогрев? И сколько он выдает мощности?
realy great video. well built engine and all the info. 👌👌
Hello great job. which is the approximate cost of the installation and what is the power output ?
would be cool to see a kit or plans which can be made with benchtop machine tools of smaller components
that Sir is a thing of beauty!
Мужики красавцы, если бы вибрации не было на сколько ещё добавилось бы!
Just had a brainstorm, could you use a scotch yoke setup for a version 2.0 ??? Just thinking out loud.
What was the wattage input? Efficiency?
That is a thing of beauty!
Интересная сборка, молодцы!!!
Could you add a larger flyweel more mass
I want to make one
vc é otimo, queria muito ter intimidade com a mecanica para construir um destes.... acho fantastico, colocaria um difusor solar pra direcionar calor ao pistão quente..... pode ajudar? Ensinar os passos pra confeccionar um que possa ser capaz de girar um alternador de corsel a 800 RPM.
great job! very good video montage of your engine. I liked the illustrations of how the engine works.
very cool machine friend
Great job! Very nice motor.
Thank you for the appreciation!
Very very nice amazing machine :)
Very good build sir, I too am considering weldments for major componants as making casting during RnD is way too expensive. I am also guessing that you are testing 3kw in = power out purely as baseline, becuase placing you engine in this config close enough to a 3kw source is going to melt it over time. To the people that say >>> 3kw in > 75w out is bad efficiency,,, I say anything is better than nothing if the source heat was just going up the stack!!! Thanks for the vid
This is nice. If someone could build and sale that for 500$ he's got my money. It comes in handy in the northern countries where most of the time you need to heat the house with wood, gas, oil whatever. While heating the house you can also generate 200watts that's enough for most things like LED lighting and a laptop or lcd tv. And if u have a battery bank and a imverter , you can charge the bat bank with the 200w from the stirling and use inverter whenever you need 2000watts for microwave, etc
so you can use ig tube steam boiler and use a steam turbine...that wud be more silent and powerful too
@jason crigger
Did you even read what he wrote? NORTHERN COUNTRIES he's probably from Norway or Holland. Not everyone here are native english spokeman. So if you are, stop criticizing those who dont.
Hi - have you calcualted the acutal efficency? You have power in and power out.. (as you say - it will never be over 50% - but I bet it is quite lower than that.) - oh 3kw in and 220w = 7.3% (just watched the video again) Still very cool!
thanks
sam
Really cool!
3000w de lâmpada para gerar quase 100w?
Интересный двигатель сделали!
Congratulations.
Hello, can you explain what is the material of pistons seals and cilinder ??
thank you!
Классный двигатель. Нужно утеплить защитный кожух над тенами, там до 2 Квт потери, и кпд получится до 20 проц.
220 Watt is not bad, nice engine
Если маховик сделать массивнее будет так ощутима просадка мощности?
Nice work sir
Thank you for support!
Very nice work. Maybe this is a stupid question, but why not use a much simpler beta design such as the Philips genset from the 1940s? It also produced 200 watts at relatively low internal pressures.
Awesome!
Good morning Sir.
I've a question please. You said that max power is 220W@700rpm but you use an electrical heating system of 3KW.
So if I'm right your efficiency is about 220/3000=> 7% .
Is it correct???
Thank you
Hi Roberto! My be even less than 7%. The engine has problems of course. Best regards!
Alexandr Fediaev I would make that engine in a program called solidworks, you know where I can get the schema and the views or drawings of that engine, very good your video. post: I am from Colombia sorrry for my English.
I've been intrigued by Sterling engines. I attempted to make one once. It didn't work. Too much friction, not enough patience on my part. I will try again some day.
I could see these as being useful for turning waste heat into power. Though, there may be more efficient ways of doing so. Especially at 7% efficiency.
yes, but if you use the smoke stack of a pellet stove as heating system, maybe you can generate electricity from an energy waste
Поздравляю, годный аппарат получился.
***** да хоть вырабатывать энергию из тепла или холода. Что за вопрос.
Ребята, у стирлинга только одно реальное преимущество - он может работать от дров, которые почти бесплатны для русских людей. Во всем остальном он в десятки раз уступает ДВСу. Плюс он оказался гораздо сложнее, чем я рассчитывал, и то, что вы видите - это говно. Я вполне адекватно к этому отношусь. Но лучше у меня пока не получется, недостаточно времени и средств.
Alexandr Fediaev согласен что карно эффективнее стирлинга, но ваши реально работают. Это не выставочный от свечки. Есть ещё один парень в Сибири, он его (горячий поршень) в печку засунул, но у него ниже эффект чем у вас поэтому он потерял интерес.
Там работы плотной еще на пару лет...
Alexandr Fediaev Удачи!
Kvalitní práce.
Very good. Have you try to pressurize with helium?
Very nice! ...I need a machine shop!...
It's like a lot of power being lost due to the Skweek somewhere The belt maybe and maybe the acoustics could be slightly altered or shifted as this is more or less a giant thermoacoustic engine that should be getting a lot more rpm but nevertheless bloody good
Klasse werk
Input 3 KW Output by 700 rpm = 200 watt = ca 8-9% Energie . Aber Super Video Danke
Alex great work my friend , kind regards Paul from Sydney Australia
Круто!
Consider hho as heat source?
Very nice
เป็นทั้งทางเลือกและทางรอด
That was very nice well done design , But if you're using a 3 kw heating source which equal 3000 watts and your target is 300, doesn't that mean that the efficiency is not more that 10 %?, correct me if I'm wrong , Thanks :)
Eng M Probably even less than 10%. A lot of errors that are visible olnly after...
Very cool, only thing I was thinking that wasn't shown here is that these engines would run quietly because no actual combustion is taking place and I thought it would run lights no problem, appears that the lights go on and off cause the generator couldn't produce enough charge fast enough. Perhaps a battery bank would heal that issue.
If they had a quite version of this that could run all the lights in our homes and maybe a fridge or more then with a simple woodstove having a system like this connected to it would mean you could run most electronics in our homes and heat our homes with just firewood.
Perhaps I'm dreaming of an impossible system. Gasification might be a better route to run a bigger generator.
Молодец, Александр! Замечательная машина! Это частное Ваше творчество или фирма?
Хорошая работа ! ; нержавейка , грамотно расположили внешний источник тепла -сверху а не снизу , как в старых .., компактный , вообще класс ! Мне показалось или нет - кольцо вытнснителя плотновато больше чем надо ..? Лайк!подписка!☺
Как я понял если источник тепла сверху, то это лучше чем снизу ?
Если да то почему ?
Greets,
great job Mr. Alexander,
What is the name of the mechanism used for connecting the crank to the pistons, and what thermodynamic phase angle that corresponds to this configuration??
Ross Yoke linkage. 90 degrees.
Ребята классно ! Вы молодец, много поработали
над ним. Один совет, если не возражаете...
Большая площадь фланцов и множество стыков
способствуют большей потерии тепла = снижение
КПД и мощности. Желаю успехов )))
put the weighted fly wheel on the alternator and the small pulley on the motor. really great handy work
VERY good job :)
Very nice 👍
Молодцы мощный двигатель
nice simple design...
If you can get some, try using helium instead of air. It is a lot better in transferring heat and also much lighter, so has less pumping losses.
Нужно чтобы генератор нагревал тены на двигателе)
И вот вам "вечный" дрыгатель)
Nice work gentlemen, nice machine work and design.... fun toy. May I suggest...?Hard line between cylinders? Hose absorbs energy through expansion, no?
Now get it to spin that alternator (or better) at full speed, charging a battery, with a slight excess of KW/HP.... while heating the top with something not electric.... think 90, 238, or 244 times for the answer. OR focused solar thermal collector, or heat reclamation from a stove/burner/furnace.
Would putter away for a lifetime, pending mechanical failure of the motor if it was running on nukey stuffs. :D All day from a hot sunny day. :D
:) Спасибо товарищ, отличная работа!
There is a hard line, through those fins at 2:48.
The external hose is just for the cooling mantle around the lower part of the hot cylinder. (It's only the upper part that is hot, the lower part is kept cold to spare the piston seals, i assume.)
Very good
Could you post more info about that engine?
I know that a blog is a time consuming "hobby", but have you think about making one with the progress of your work? I would be glad to read it :)
Maybe you already know about it, but have you heard about WhisperGen?
If you are using a permanent magnet alternator, you are as efficient as possible, since you won't waste any power running the field. A hover-board wheel or two should be about right for 300 watts. They operate at a fairly low RPM. You must have a 3-phase rectifier for each wheel, to get DC power out. A Maximum Power Point Tracking (MPPT) solar charge controller may be able to find the perfect load to get the most wattage out of it. If you want a bigger generator, consider using one of those clothes washing machine motors that's built like a hover-board wheel, but a lot bigger. It could probably be direct-drive from the crankshaft of this engine, and save the friction of the belt.
Pomimo prostej technologii wykonania Wasz silnik działa wyśmienicie osiągając realne moce użytkowe. Szkoda ,że nie jest ogrzewany np drewnem wtedy byłby ekologicznym generatorem. Ale rozumiem ,że do prób zrobiliście tak jak mogliście. Teraz produkować i sprzedawać jako awaryjny generator na wieś. 😀Pozdrawiam i gratuluję wyniku.
i live in Egypt < we have big problem in electricity < maybe u know about it < could u advise what to do
Hi Ahmed! This engine in not ready for production now. It is only an experiment. Now I'm working on next engines that must be better. If I could manage to make good engine that can be work for long time we could talk again. Best regards from Russia!
Alexandr Fediaev thax for ur reply < i belive u will do it < and i hope if it be more simple and not coat alot
Ahmed Ghonam I would use concentrated solar to make steam, to power a turbine generator, or piston steam generator. To charge batteries, for inverter. That's what I'd do if I had more sun. I still may, but use wood fire to generate steam.
Great Engine design. Just wanted to ask what material you used for the piston seals? Putting a water jacket round the hot piston seal was a nice design touch.
Hi! I used a graphite filled PTFE, but it was bad solution because of big thermal expansion and too big fricton... It failed at last. At this time I have no good solutions at sealing :(
@@sasafed1970 Thankyou for your reply. Hot end seals do seem to be the akillies heal of stirling engine design. If you stick with a piston design and have access to a lathe, the best solution seems to be a solid graphite piston or graphite piston rings. This still isnt a great solution since one company I looked at for graphite piston rings only rated them for 10,000 hours. I'm sad your water jacket didn't work. From what I can tell, The big solar engines are using diaphragms that are cooled. This does however limit running pressure.
@@RoadRashSpirit you are right. Here you could see my diaphraghm design
czcams.com/video/bQ1wOIsrEUA/video.html
@@sasafed1970 Watched it, very nice. Will have a look at the Nasa rolling Diaphragm. Is it in direct contact with the heat?
Just had a quick look at rolling diaphragms, very interesting design. Do you have any information or a link to where you found your information on construction and material design? My basic knoledge is that Butyl is used. Is that also what you used?
@@RoadRashSpirit My design of rolling diaphragm is true inspired by NASA, but I used 1.5 mm silicone sheet as diaphragm. It withstand 4 bar of air and contacts with sleeve of about 200 Celsius. If you need more info please write at sasafed@gmail.com It is not comfortable for me to talk here. Best regards!
You know you may not get a lot of torque out of one of these engines. But if you don't have a really big load or a direct load, there is plenty of power to produce electricity. For something like charging batteries. Like a windmill you only have so much power and as long as you don't have a load you can charge batteries just fine and you can run the load off those batteries but you can't let the generators see the load. It will take it out of sync with the wind. I would love to see something like this configured for the top of a wood burning stove
Молодцы! 👍
при всем уважении Александр, хотелось узнать данный двигатель можно приспособить к теплу от терминальной воды.
+Дидар Карымсак К сожалению нельзя. Для этого двигателя температура должна быть 600 градусов.
спасибо за совет.
Das ist so cool will auch eins in der größe
very good
Спасибо! Пока частное творчество, но если сумею выйти на расчетный уровень мощности то может и промышленном производстве задумаюсь.
Здравствуйте, ппродаете двигатель?

If you remove the rectifier from the back of the alternator it will produce 120v alternating current
Alexadr Fediave, Hi friend.I would make that engine in a program called solidworks, you know where I can get the schema and the views or drawings of that engine, very good your video.
Hi Jose! It is spent 3 years from the project and I have no any materials about the engine except the video. (And the engine itself is melted on recycled metal of course) Mechanical construction is clear from rendering. All dimensions were depended on scrap parts that I used and will be other in your design. I can answer your questions though. Best regards.
thanks for responding friend, greetings, very good your video.
Thumbs up & subscribed. Could this be done to genarate about 5kw of power?. Thanks for sharing.
This machine is small. You have to find the "ST-5 stirling engine" on youtube. It can produce up to 5 horse power. Thanks!
Thank you so much.
Alexandr Fediaev
That shows you the problem with Stirlings: the ST-5 is HUGE, but produces 5kw, the same as a little Honda lawn mower engine
nice dood!
Of course I know :)
First - heat exchange decreases because of lack of time (short cycle)
Second - fluid flow loses increase (as square) because of high speed
At 1200 rpm First = Second and the power = 0. Regards.
Как Ваши поиски?тема живая?
@@user-xl2ok4cr7q Очень сложный вопрос. Тема оказалась гораздо сложнее, чем я изначально рассчитывал. И требует колоссальных вложений, причем не столько даже денежных, сколько по времени. С учетом того, что у меня семья, пока отложил на некоторое время, так как нет возможности одновременно двигать и станки по шелкухе и стирлинги, но не отказался, так как вижу что шанс есть, просто отложил пока до лучших времен.
класс молодцы приятно смотреть уважаю
Cool!
Hi Job! Like most of stirling modelists I have no complete drawings because I did not need it. Parts was made from some scrap and some old laser cuttings parts from old projects. Main actual parameters you can see at video beginning. Design is full dependent of available materials, tools and skills.
Здравствуйте Александр!Скажите,как вы выходной вал загерметизировали?
Торцевое уплотнение из фторопласта. Раньше оно называлось "Ленинградское уплотнение". Пожалуй единственная часть этого двигателя, которая работала идеально. Почти без трения и без просвистов.
Alexandr Fediaev Спасибо за быстрый ответ!Надо же,когда говорят о стирлингах под давлением,этот узел считают чуть ли не самым сложным.А оно вон как)))Идеально и не свистит.
Alexandr Fediaev Погуглил,попадаются уплотнения для насосов.Вы сами делали или это готовое изделие?
Делал сам. Там нет ничего сложного.
The goal for my final defree project is to make a microcogeneration unit, some sort of Whisper-Gen, but i have a lot of research to do yet :)
Connect a power inverter and then turn on the switch the electrical part to the inverter.
gud work
Sir I'm working on a stirling engine project. So can you help me by providing some plan for the stirling engine project..
I have no ready plans. And all engines that I made are not engines itself but some test equipment to investigate some solutions... I could advice you if you ask a question.
Search on internet for James Rizzo he has lots of books and plans for Stirling engines.
I didn't understand. How does this operate again? Air?
Heater on top (unusual place for a Stirling, but with this design it works).
The added air is to increase the internal working pressure, since gas (air) under pressure can transfer more heat between the "hot" and "cold" cylinder, which increases overall efficiency.
why, when you put a load in the generator, it create more friction and reduce the speed of the engine, if I know that the generation of electric energy is because of the induction, and the coils and the magnet, don't touch, why do that generates friction?
thanks for any answer it could help me in my dude
It doesn't generate friction the way you're thinking. Nothing is physically rubbing. You've got magnetic fields pushing on each other inside the alternator to generate the electrical potential. The faster the electricity flows out of the alternator, the stronger the fields become and the more force is required to push them past each other.
(Gross over-simplification, but try rubbing refrigerator magnets on each other. The stronger the magnets, the harder you have to push. Same idea.)
What was the Kalvin of your Heat sink and recharge?
Heater was about 900K - red hot. Cooler was cooled by water. About 330K.
So with respect to gas law this would be a 1 to 3 ratio. Check my math. Have you tried running a colder heatsink or is this the engine efficiency rang.
I tried 2 buckets of water. This small amount is heating fast enough to try for lower temperature.
I would like to see you tone the recharger and heat sink too its best performance ratio. You helped me premeditate the math a little better with mine. Thank you. I'm working on a Alpha 4.
Beautiful. That's a Stirling *engine*, not a Stirling desk toy.
