I think the point has been missed here. The generator is rated at 50W nowhere does this video claim to be producing 50W. Just because the engine spins the generator doesn’t mean that it’s producing 50W, I think we can all agree on that. This video does however provide value if you take the time to watch, in my view the 50W question is irrelevant. What we should be focussed on is the fact that waste heat can be utilised and harnessed to generate electricity of some description. If we spent more time and energy focussed on how some of these technologies can be applied rather than destroying the conceptual basis from our keyboards then perhaps we’d encourage those both inside and outside the engineering profession to experiment more without judgement and further the knowledge and understanding of alternative technologies to a point where they could be cost effectively employed. Surely proactive commentary is far more useful than criticisms of those that are actually prepared to put time and effort into these endeavours for us all to learn from, even if the basis or numeracy involved is partially flawed.

The 50W is totally relevant as it shows the problem with this engine, and that is that it's not efficient enough over a steam engine to replace it. This design is over 200 years old and the inventor was hoping it would replace steam engines. The problem is easy to see with this video. Any time he starts to load down the "generator", the RPMs drop off significantly because the motor can't deliver the torque needed to maintain the RPM. If it could then we'd be seeing loads of these engines.and people wouldn't be going after the 50W claim in the title of the video as there would be a good chance it's true. The claim in the title is no different than someone saying the have a perpetual motion machine. If you want to learn about Stirling Engines there are better videos and sources of information. This guy gets an A for effort, but a D for content.

@@dsherman9438 I could probably teach you a whole lot about sterling engines. The company I own builds units up to 40kw for low energy heat recovery from boiler flues. I’m well aware of their limitations. My point is that KZhead and content creators like this gentleman provide a valuable source of inspiration to many people some not privileged enough to have the benefit of engineering degree like you or I might enjoy. However the value of this as a proof of concept demonstration offers inspiration to others to do the research and become passionate in the exploration of these technologies. As a society we are too pedantic and entrenched in the minute details like the 50W stated in this video to look at the potential of technology and the application it could have in bettering lives and education. Basic common sense says that the heat source is not 50W and therefore the unit will never support a 50W load, I don’t dispute that however somewhere out there, there are people that will be inspired by this video and will use that inspiration to further their education, their inspiration and possibly even create a life long path of innovation. KZhead is no substitute for your own research and education but as a source for ideas and inspiration I think it’s fantastic and for me anyway as an engineer who specialises in renewable technologies this makes the 50W irrelevant in the context of the content.

@@davidtokelove3358 That's all fine and dandy, but the big thing here, as is in real engineering is to never put thing out there that aren't true. Also, if you are going to make claims then you better be able to back them up. Saying that this video may inspire someone to pursue engineering is irrelevant as the video will do that regardless of the comments. That too is a learning tool for them as they begin to see this persons mistakes. I doubt very much that it dissuaded them from any inspiration they got from watching the video. If it dissuaded them from anything I would think that it would dissuade them from posting videos with claims they can't explain or are unrealistic. Hopefully the person who posted the video sees where they went wrong and does more research. Criticism, especially negative criticism is a great opportunity to learn from, as well as give even more incentive to learn more. Telling people to not point out the truth for the sake of hurting someones feelings or stopping someone from making another video that might inspire others seems more detrimental than negative criticisms. My best professors were the ones who would often deliver the harshest critics. Their reason was, "How are you going to learn if everyone pats you on the head all the time, even when you are wrong?"

Assume, that you have 4 grams of alcohol in the burner and it burns for 30 min. Caloric value of ethanol is 29.7 kJ/g. It gives in total around 60 W of thermal power (at the best of best theoretical cases). Let, s assume, that half of this power gets to the air in Stirling engine. It gives 30 W of thermal input. The efficiency of such a toy stirling engine is of the order of a few percent (let's say generously: 10 percent, as of an excellent industrial, first half of 20-th century steam engine). It gives mechanical output of 3 W at peak at the output shaft of the engine. Where the author wants to get 50 W of electric energy from? If the output is of the order of 1 - 2 W - congratulations. If you claim it to be 50 W of electric power - prove it by measuring voltage and current through the load.

Not 50. A regular tea candle varies from about 30 watt to about fifty and slightly more depending on size, chemical energy. Then you have heat losses , and then the stirling cycle efficiency of 15 to 30 percent at max. So , if you use lets say now a 70 wattt flame as it is a bit larger, theroretcially you can even without heat losses not get more than 10.5 watts for a 15 % engine taken in to account that it is a simple model. Then subtract heat losses in the transfer whereas not more than half of the cylindrical surface is covered, and thus it is far less than 10 watts but not easy to calculate without knowing the dimensions, but it is clear it is less, probably about 2 watt. Now, i have been working with boiler designs for more than 20 years as an engineer, there is no way, absolutely no way, it gives 50 watts. Now, this was very high figures, a basic estimation without even calculating it would be about half a watt or close to one at max as you have no cooling fins, no economiser and a rubberband transmission.

@@yalmanmfp well if you get 40% you really have to look in to gas exchange etc. it is possible, but not on this version, mostly you need helium or similar to reach 40, and it is basically not the theoretical data as much as most people do pretty shitty constructions and get friction problems in pistons etc and thats why i rather believe this wont go above 20% . It also depends wich type of cyckle model you use to get the various efficiencies. as of now there is very little possibilities to make a stirling both efficient and small for lets say a car, but submarines use them as well as generators where they dont rely on weigth.

A volt meter is not a load. To measure power you need a load. You would use Ohm's law and compute power as voltage times current. That setup looks that it would produce some milliwatts of power. You can measure the voltage across a 1k ohm resistor as a load, and then the voltage measured on your meter would correspond to milliwatts of power generated. If instead you use a 100 ohm resistor, the volt meter will read in tens of milliwatts, etc.. 250 milliwatts is 1/4 watt, so if you have more power than that you need to use a higher rated resistor or put together a network of them. A single diode voltage drop is typically 0.6V so if you had 100 milliamps running through that (my guess in that setup), it would correspond to producing 60 milliwatts of power. LEDs are very efficient at making light. Of course it would be great to see real numbers rather than my guesses - but that is how you would get real numbers. ... The generator rating would correspond to how much power it is designed to produce when connected to a specified load and turned at a specified number of RPMs. If you turn it faster than that number of RPMs, you can generate more power, but the generator might be harmed. If you use a different load than specified, then there will be a different ideal RPM number, if any, and a different power rating at that RPM. You have to read the specs for the generator. At lower RPMs and a non-ideal load value including very high resistance values for load (such as your volt meter), the generator will deliver less power. So as a wild made up example, say you connected a 50 ohm load to that generator, and the generator was spun at sufficient RPMs that it put 1 amp through that load, then there would be 50 volts across the load, and the generator would be delivering 50 watts of power, and the load would be dissipating 50 watts. If you used a resistor for a load, then the resistor would have to be rated at 50 watts. In that case, if it is possible, the Stirling engine would be doing more than 50 watts of work depending on the efficiency of the generator, and that Bunsen burner would producing over 50 watts of heat, depending on the efficiency of the Stirling engine and the generator. Gosh it would be great to see that setup under various loads to see what it would really do. You have a good start. Now you need some resistors to use as loads.

Maybe place the heat bulb into your car's exhaust pipe and reclaim some of that heat energy to charge a battery, or run the headlights, radio, and Air Conditioner. 😂 just kidding. No one will poke holes in their exhaust to conduct this experiment.

lol
It's around 50W. Thank you for watching! have a nice day.
Thank you.
Ok test it, try to power a phone fast charger or a laptop
No, it’s not. A lot less
I think the point has been missed here. The generator is rated at 50W nowhere does this video claim to be producing 50W. Just because the engine spins the generator doesn’t mean that it’s producing 50W, I think we can all agree on that. This video does however provide value if you take the time to watch, in my view the 50W question is irrelevant. What we should be focussed on is the fact that waste heat can be utilised and harnessed to generate electricity of some description. If we spent more time and energy focussed on how some of these technologies can be applied rather than destroying the conceptual basis from our keyboards then perhaps we’d encourage those both inside and outside the engineering profession to experiment more without judgement and further the knowledge and understanding of alternative technologies to a point where they could be cost effectively employed. Surely proactive commentary is far more useful than criticisms of those that are actually prepared to put time and effort into these endeavours for us all to learn from, even if the basis or numeracy involved is partially flawed.
The 50W is totally relevant as it shows the problem with this engine, and that is that it's not efficient enough over a steam engine to replace it. This design is over 200 years old and the inventor was hoping it would replace steam engines. The problem is easy to see with this video. Any time he starts to load down the "generator", the RPMs drop off significantly because the motor can't deliver the torque needed to maintain the RPM. If it could then we'd be seeing loads of these engines.and people wouldn't be going after the 50W claim in the title of the video as there would be a good chance it's true. The claim in the title is no different than someone saying the have a perpetual motion machine. If you want to learn about Stirling Engines there are better videos and sources of information. This guy gets an A for effort, but a D for content.
@@dsherman9438 I could probably teach you a whole lot about sterling engines. The company I own builds units up to 40kw for low energy heat recovery from boiler flues. I’m well aware of their limitations. My point is that KZhead and content creators like this gentleman provide a valuable source of inspiration to many people some not privileged enough to have the benefit of engineering degree like you or I might enjoy. However the value of this as a proof of concept demonstration offers inspiration to others to do the research and become passionate in the exploration of these technologies. As a society we are too pedantic and entrenched in the minute details like the 50W stated in this video to look at the potential of technology and the application it could have in bettering lives and education. Basic common sense says that the heat source is not 50W and therefore the unit will never support a 50W load, I don’t dispute that however somewhere out there, there are people that will be inspired by this video and will use that inspiration to further their education, their inspiration and possibly even create a life long path of innovation. KZhead is no substitute for your own research and education but as a source for ideas and inspiration I think it’s fantastic and for me anyway as an engineer who specialises in renewable technologies this makes the 50W irrelevant in the context of the content.
@@davidtokelove3358 That's all fine and dandy, but the big thing here, as is in real engineering is to never put thing out there that aren't true. Also, if you are going to make claims then you better be able to back them up. Saying that this video may inspire someone to pursue engineering is irrelevant as the video will do that regardless of the comments. That too is a learning tool for them as they begin to see this persons mistakes. I doubt very much that it dissuaded them from any inspiration they got from watching the video. If it dissuaded them from anything I would think that it would dissuade them from posting videos with claims they can't explain or are unrealistic. Hopefully the person who posted the video sees where they went wrong and does more research. Criticism, especially negative criticism is a great opportunity to learn from, as well as give even more incentive to learn more. Telling people to not point out the truth for the sake of hurting someones feelings or stopping someone from making another video that might inspire others seems more detrimental than negative criticisms. My best professors were the ones who would often deliver the harshest critics. Their reason was, "How are you going to learn if everyone pats you on the head all the time, even when you are wrong?"
@@dsherman9438 Fair enough. I have my opinion and you have yours. I will keep KZhead for entertainment and the workshop floor for engineering. I still think you have missed my point completely but I’m happy to respect your opinion.
@@davidtokelove3358I don't think I've missed your point. I just don't think that people rightfully pointing out a false claim will detract from people being inspired by the video. I think I have more faith in people and the fact that regardless of any shortfalls, it's a fascinating engine that's hard not to be inspired by.
There is no way that generator output is 50W. Measure current instead of spreading lies.
It looks like it would be about 100 mA and 5v output I bet. At most half a watt
0.1W less for sure
It’s a 50 watt motor, but it’s outputting 26 watts. Did you watch the video?
@@NinjasOfOrca It's actually putting out 26 VAC. There is no load on the 50 watt alternator so it's not producing any power.

Assume, that you have 4 grams of alcohol in the burner and it burns for 30 min. Caloric value of ethanol is 29.7 kJ/g. It gives in total around 60 W of thermal power (at the best of best theoretical cases). Let, s assume, that half of this power gets to the air in Stirling engine. It gives 30 W of thermal input. The efficiency of such a toy stirling engine is of the order of a few percent (let's say generously: 10 percent, as of an excellent industrial, first half of 20-th century steam engine). It gives mechanical output of 3 W at peak at the output shaft of the engine. Where the author wants to get 50 W of electric energy from? If the output is of the order of 1 - 2 W - congratulations. If you claim it to be 50 W of electric power - prove it by measuring voltage and current through the load.
coupled with a natural heat source (hot spring, lava flow, heat from the sun) and you get free energy!!
@@JoeBourne_UK Yes, but you must have this free source of energy. And sometimes, it is economically not justified, even if the thermal energy is free, the generator is more expensive than the energy it will produce during it's life. You will not get around with some warm stream of water flowing from the rock. You need a really decent source of geothermal energy, so investment in machines is justified. The common mistake made by enthusiasts of renewable, "free" energy is lack of solid calculations (not mentioning the perpetuum mobile magnet machines enthusiasts) and lack of realistic, quantitative assessment of natural conditions they have.
The Stirling engine is coupled to a 50w rated dynamo; no one is claiming it produces 50w of electrical power.
Such a model does not even theoretically give 1 W
Hi dear . It's really around 50W.
@@TopTechDiy its not
@@TopTechDiy could you please develop ? Saying something doesn't make it magically true (yeah, I know, an old concept from Europe)
@@TopTechDiy The fact of turn on a led of 50W does not mean that the real output is 50W, a real test is measure current and voltage applied to a lod (could be led light) remember Oms law P=V*I, thanks for the experiment have a nice day :)
this is toy model.. the real stirling engine size is 5-10x more.. HOWEWER if he try with car alternator,results may be a noticable... i mean connect truck alternator to stirling engine. even toy engine can run it but you need to start it with your hand,then it will run fine,it will spin up very slowly. i did try with car alternator taken from honda civic and results vere satisfactory. - 14 volts and 100 miliampers. i think it was 0,65W or less. fun fact stirling engine were tested in trains but results were poor plus size of engine was of whole room.. i
I read some of the comments. That being said i believe the Sterling engine can be very useful. I personally don't care about industrial application. But for personal use i.e. if someone was living off grid or in a camper this setup with a little modification could be quite useful.
Stirling engines cannot run any computer. There's a reason nobody off grid actually uses them. They suck at being engines
I made the same thing with a more powerful Stirling engine and the same generator and it outputs 2.2 watts! 50 watts my arse
You're telling me that little motor produces nearly two amps at 26 v? If it can push that kind of current, I'll eat my hat.
I’ve a similar motor than that, it was inside a printer and operates at 32v, i tried rotating it with a dremel at arround 32K rpm and it was generating over 60v. Then it stopped working. But his motor is barely generating 5W
Its 50 kilowatts, why you write so little power
Not 50. A regular tea candle varies from about 30 watt to about fifty and slightly more depending on size, chemical energy. Then you have heat losses , and then the stirling cycle efficiency of 15 to 30 percent at max. So , if you use lets say now a 70 wattt flame as it is a bit larger, theroretcially you can even without heat losses not get more than 10.5 watts for a 15 % engine taken in to account that it is a simple model. Then subtract heat losses in the transfer whereas not more than half of the cylindrical surface is covered, and thus it is far less than 10 watts but not easy to calculate without knowing the dimensions, but it is clear it is less, probably about 2 watt. Now, i have been working with boiler designs for more than 20 years as an engineer, there is no way, absolutely no way, it gives 50 watts. Now, this was very high figures, a basic estimation without even calculating it would be about half a watt or close to one at max as you have no cooling fins, no economiser and a rubberband transmission.
1.stirling engines max efficiency %40 2.Tittle says 50w generator WITH stirling engine(No body says this stirling engine produce 50w but yes its tricky title) 3.Thank you for information bro i realy in love with stirling engines i enjoy it read anything about them
@@yalmanmfp well if you get 40% you really have to look in to gas exchange etc. it is possible, but not on this version, mostly you need helium or similar to reach 40, and it is basically not the theoretical data as much as most people do pretty shitty constructions and get friction problems in pistons etc and thats why i rather believe this wont go above 20% . It also depends wich type of cyckle model you use to get the various efficiencies. as of now there is very little possibilities to make a stirling both efficient and small for lets say a car, but submarines use them as well as generators where they dont rely on weigth.
@@jonjonsson6323 dont get me wrong i agree with you i just want to fix missleading parts i m pretty sure this one have very low efiency and probably only generate around 0.1-0.50 watt because of volume and cooling design
@@yalmanmfp yes and no, but you also cannot get more out than in. the limit is the heat sourse and the size and type of stirling. in the region of that size, a simple solar cell gives more ,,it is not magic really, the stirling process is never gonna be better than the diagrams on paper wich even there is lesser efficient than many engines,. the benefit comes not from power, but from the sources of power you may utilize such as excessive heat , sun etc. if it had been a matter of power, a steam turbine would been best as it is the only real source above a few megawatts size wise.
@@jonjonsson6323 for now i agree with you but hopefullly metarial science is awesome and there is hope for future
Very impressive, just Goa's to show that these little engines can be useful, good video
I think he meant, 50 watt dynamo with stirling engine. Stop roasting him haha
I bought the same dynamo and it outputs 9 watts
While I seriously doubt the claim regarding the output I can definitely see these as being worthwhile if you’re living in an off-grid situation. If you’re going to buy that and try it get yourself a capacitor to smooth out the current after the bridge rectifier converts it to DC.
If the generator is some sort of permanent magnet motor, in my extremely limited experience, you can hardly turn those motor axles with your finger. That engine would only turn such a motor, if the magnets have been removed. And prossibly batteries installed where the magnets were.
Yes, you are correct.. something doesn't add up here.
This stirling engine can only power a single led. 1-2watts. 98% less power than your description. At 10w torque, the glass cylinder will explode because of the high pressure. For 50w you will need a massive stirling engine and a stove flame
There is no link posted I would really appreciate a parts list
this does not mean it generates 50 W with this engine. It's just a 50 W capable generator connected to a stirling engine. And the author let us speculate, what output power this could be. According to my experience, this is about 100 to 200 mW. Much more power output can be seen here: kzhead.info/sun/iLV_laaFmZ-PdZE/bejne.html
It would be a nice idea to put that AC through a bridge rectifier and into an LED light. Some ornate miniature street lamp also attached to the main platform. A nice conversation piece light source at a late night BBQ.
I have a stirling engine bigger than that one and it only makes 1 watt just because the alternator is 50 watts doesn’t mean it can push 50 watts
What is name of generating motor??????
That's a brush motor !!!! It produces cc !!! Not ac!!!! Your multimeter is ........
this setup is in the miliwatts range. dont misguide the viewers
If this was generating 50W of electricity, the Airline business would be using slightly scaled up versions of these to power electric generators on planes. 50W is a BOLD lie
I want one but the link in the description doesn't go to this particular model.
Next time put a electric meter on the leads to see how much power its putting out instead of making a clickbait video. No way that motor is producing a 50 watt output.
how would a 50 watt output be achieved ? higher rpm ?
Can you please share the number part or model of that electric motor. That stirling motor spins at 1700-2000rpm. Everyone can do the math with that information. Thank you
50 watts over 50 days of continual run time maybe.
Why is your multimeter set to AC? This motor should be outputting DC, no?
People, don’t hate on this guy. You can actually hear the engine note changing
Hi, where do you get the Generator?
The best choice use stirling engine homeade, more power and more rpm Can be get more voltage, i guess this engine just 800 or 600rpm
wow, very good, but you are measuring direct current in the multimeter's alternating current mode, does that not cause a problem with it?
Or maybe it's an alternator with no bridge rectifier so measuring on the AC scale would be correct.
where is the 2 amp at 25 volt load?
Notice w the smallest load it cuts r.p.m. in half?
Do you know what is 50 watts of power.
Ficou bem feitinho o suporte do motor. Mas o elástico e a escolha de cilindros pequenos mostra pouco conhecimento. O multímetro sem os bornes faz crer que já foi jogado fora. Sua idéia é a da maioria dos que assistem o vídeo. Mas está elementar demais. Siga em frente.

If you out the rubberband around the flywheel instead of the spindle at the end, the gear ratio will give you faster spin and thus more juice.
Then it would not run... At all
then it requires more torque

It's very unusual for such a small Stirling engine to power a dynamo of that size.
You should not use 30V led since generator output is just 28V.there is a shortage. You should have used 2-3 volts led's, putting some resistors in them.
Thx for sharing. Please post the VA output of the alternator. What is the output of the flame in Watts? Then it could be shown how efficient the Stirling engine is. The title does imply something close to 50W output or even half. Redo this and post the numbers. Thx in advance.
0.5 watts is realistic.
There's no way that would drive a permanent magnet motor at that speed. For starters the elastic band would break. He has obviously taken out the magnets from the motor.
Yes, Stirling engines are very weak, in relation to their size.. I too thought it very unusual for an engine of such a small size to run a generator that big.
Super charge it with a torch
Thanks for being honest
A volt meter is not a load. To measure power you need a load. You would use Ohm's law and compute power as voltage times current. That setup looks that it would produce some milliwatts of power. You can measure the voltage across a 1k ohm resistor as a load, and then the voltage measured on your meter would correspond to milliwatts of power generated. If instead you use a 100 ohm resistor, the volt meter will read in tens of milliwatts, etc.. 250 milliwatts is 1/4 watt, so if you have more power than that you need to use a higher rated resistor or put together a network of them. A single diode voltage drop is typically 0.6V so if you had 100 milliamps running through that (my guess in that setup), it would correspond to producing 60 milliwatts of power. LEDs are very efficient at making light. Of course it would be great to see real numbers rather than my guesses - but that is how you would get real numbers. ... The generator rating would correspond to how much power it is designed to produce when connected to a specified load and turned at a specified number of RPMs. If you turn it faster than that number of RPMs, you can generate more power, but the generator might be harmed. If you use a different load than specified, then there will be a different ideal RPM number, if any, and a different power rating at that RPM. You have to read the specs for the generator. At lower RPMs and a non-ideal load value including very high resistance values for load (such as your volt meter), the generator will deliver less power. So as a wild made up example, say you connected a 50 ohm load to that generator, and the generator was spun at sufficient RPMs that it put 1 amp through that load, then there would be 50 volts across the load, and the generator would be delivering 50 watts of power, and the load would be dissipating 50 watts. If you used a resistor for a load, then the resistor would have to be rated at 50 watts. In that case, if it is possible, the Stirling engine would be doing more than 50 watts of work depending on the efficiency of the generator, and that Bunsen burner would producing over 50 watts of heat, depending on the efficiency of the Stirling engine and the generator. Gosh it would be great to see that setup under various loads to see what it would really do. You have a good start. Now you need some resistors to use as loads.
50 watts trough a rubber band belt 😅
put a 12v 5W light bulb does not light up the engine will stop

Can I buy this model ?
Capacitor banck after your inverter transiter will help with your brownouts
where is the load. To properly calculate the load of a generator, A precise load such as a power resistor at a known value plus the voltage and current drawn. Everything in this video is speculative. Most of these stirling engines use isopropyl alcohol for fuel. I was curious about burning hydrogen but the flame may be too hot. I sure there other fuels that could be subsituted.
That is about 2w of light
I agree with the comment below - ain't no way a 50Watt!
Parts kharidne k liye kya karna hoga
Is it possible that the 25.0 was supposed to be doubled because the measurement the meter was using was smaller?
They can only manage about 0.05 Amps by the looks. Not even close.
There can't be more power generated than the btu output of the flame.
Very cool. I think Bitcoin miners should use the excess heat of their miners to power a sterling generator.
