Outstanding work, that is a masterpiece of mechanical engineering, i'm very close to making the worlds smallest LTD Stirling, its 1 inch in diameter and 2 inches tall, it won't run on anywhere near as low a delta t as your baby tho, good work csizmarikg.
That is beautiful! For those looking to find the differential in Fahrenheit...you don't calculate 4.4C to 39.92F. You must calculate the two Actual Values first. So 27C = 80.6F and 31.4C = 88.52F....Now calculate the difference. 88.52F - 80.6F = 7.92F I see there is a lot of debate on this video about this....so sad. Excelent Video and Top Notch Build!
One of the best ltd stirling I ever saw on youtube Is very difficult to make it to have such a low friction Also is difficult to respect exactly the geometry :parallel ,straight ungles etc. And also to be as light as possible and airtight
What Is Islam? Islam is not just another religion. It is the same message preached by Moses, Jesus and Abraham. Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. It reminds us that since God created us, no one should be worshipped except God alone. It also teaches that God is nothing like a human being or like anything that we can imagine. The concept of God is summarized in the Quran as: { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) Becoming a Muslim is not turning your back to Jesus. Rather it’s going back to the original teachings of Jesus and obeying him. More ....
I saw in one of your previous responses that if you increased the temperature to the point a normal sterling engine works at, that it would melt the parts. If you raised the heat (but not to the point of melting the sensitive parts) and increased the cooling ability, would it provide a better output, and possibly be able to produce energy?
I want to make one of these with cooling fins on the top plate, small radial fins on the outside of the flywheel and a shroud to enclose the outer part of the flywheel, air-cooling the top plate.
For raw cooling capacity, yes, but that would require closed plumbing, a second heat exchanger and reservoir to cool the water back down and a LOT more power to physically move the water around.
This is great! I would like to see a LTD engine that is under pressure and see how low of a temperature differential one could get with that. I know the record for an atm LTD engine is 0.5C by Dr. Senft...I wonder if a pressurized engine could get even lower.
incredible! I am looking to build a stirling engine, i have built 3 already but all have failed. Were did you get the plans for your engine? i would like to make mine using those plans. thanks!
it has heat the table top, by adding the wet paper on top, it causes a temperature differential because the wet paper has water (or what ever he used) evaporating lowwering the temperature of the top, thus the heat is from the room temperature table top now being hotter then the wet paper.
Üdv ! Grat a szerkezethez ! Ha lehetne 1 nagy kérésem el tudnád küldeni az alkatrészek pontos méreteit, rajzát és hogy mi milyen anyagból készült? Szeretnék én is egy hasonló kis masinát :)
As I understand how these widgets run is that there is a higher temperature and a lower one. And a fixed volume of air? With a spacer that is about 2/3 of the total volume, that is attached to an oscillation mechanism. The oscillation allows the air that is internal to the fixed volume. The oscillation of the air, so that it is cooled, drives the oscillation. The demonstration seems to apply an insulation to the cooling side; it would seem then that there is less of a temperature differential within the mechanism thereby. But yet it seems to work, perhaps better than without the described insulator. Huh? Please explain.
true, which is why i said the oops in your comment, I figured thats what you ment, but big difference in the phases of "Engine doesn't need heat" and "don't have to add additional heat" which is why i called it an "oops" just like my oops of the typeo of opps....lol anyway have a great day..
@teslstirlputt That's pretty funny because water freezes at 0ºc and 32ºf but magically 4.4ºc is way below freezing. °C x 9/5 + 32 = °F (°F - 32) x 5/9 = °C
Hi, I have an idea for generating some substantial amount of electricity. However i need a high power LTD free piston Stirling engine resonating at about 50 Hz. I was thinking of pressurizing it to about 50 bar and running it with warm and cold water flowing trough heat exchangers inside the housing. We are talking about maybe delta T=25 to 30 deg. Celsius. Can you help me with the design? We need hard, cold math so it's the smallest we can make it. Water supply is constant temperature and the amount of water at my disposal is about 50L/min. Maximum temperature is 80deg. Celsius, so we can use plastic for some parts.
Does someone know if it work if we tilt the motor? For exemple: when the heat source is a parabolic dishes, the central point of this parabol constrained to tilt the motor. Answer me asap, ty in advance ;)
+Les Rape-Tout Vilsmissiens With this design the displacer piston/disc has no bearings and no friction, as there is a gap in the bottom chamber. If you tilt the motor, the displacer rubs the wall. You would need to engineer some kind of levers and rods to locate the displacer. Horizontal Stirlings use steel wool as the displacer/regenerator, but usually use a burner or candle, and are not Ultra LTD.
Technically you don't have to add additional heat. All you need is a hot and a cold reservoir. Rather than adding heat to the hot side, he is removing heat from the cold side. I guess it depends on how you interpret his original question. I interpreted it as "How does the engine run without heat being added."
wrong, a stirling engine is a caloric engine or heat engine. meaning it works with a temperature differential (like you said) which means it works because of the conduction of energy(heat) from hot to cold... just because he added a cold "thing" (the wet paper) does not mean there is not a heat source, it just means the heat source is room temperature or ambient temperature but still a heat source.
You should take your own advice. First 4.4C is the differential...NOT the absolute value. Do the math properly...although a differential can be found without it being so convoluted...I will help you. 27C = 80.6F and 31.4C = 88.52F 88.52F - 80.6F = 7.92F The tempurature differential in Fahrenheit is...dun dun dun...7.92F

It's pretty impressive that it can run at such low differentials.
Now that's a cracking piece of engineering,,, every aspect refined to been as near perfect as possible ,,,,
Outstanding work, that is a masterpiece of mechanical engineering, i'm very close to making the worlds smallest LTD Stirling, its 1 inch in diameter and 2 inches tall, it won't run on anywhere near as low a delta t as your baby tho, good work csizmarikg.
I have to say "perfect job"!
The 2.5 deg. makes impression !
this is the BEST ENGINE I have ever seen...
You like to do things the other way around! Instead of heating up the bottom... U cool down the top. I love it! +
the best !!
congrats
excellent engineering!

Excelent Video and Top Notch Build!
or simply multiply the dT by 9 and divide by 5 :)
@teslstirlputt this is by far best. minimum heat is the true test. congradulations
Incredible!
Amazed well done
One of the best ltd stirling I ever saw on youtube
Is very difficult to make it to have such a low friction Also is difficult to respect exactly the geometry :parallel ,straight ungles etc. And also to be as light as possible and airtight
Whaw ! Amasing !!!!
Tanks 4 sharing
Really great job! Congratulations
You must sell it and become rich!!
Do you have a video record of building? Id love to see it.

Fantastic!
You can not find the same in the world.
5*
Wish I could buy something like this, haven't been able to find any that work this well
Excelente work, and very impresive; it works with such a low temperature diference! What about a "how to make it" video tutorial? :-D
you are the best that I have ever seen
www.amazon.com/ELENKER-Temperature-Stirling-Engine-Education/dp/B01ABU3Q2M?th=1
I have a couple questions. what did you use for a bearing? and what did you make the displacer and power piston out of?
thanks
A very beautifully constructed engine. Have you used a diaphragm piston?
cool very nice thats the best on youtube

Cold water is more effective i think
For raw cooling capacity, yes, but that would require closed plumbing, a second heat exchanger and reservoir to cool the water back down and a LOT more power to physically move the water around.
How did you get or make the plates and tube that make up the displacer chamber?
@teslstirlputt 4.4C is indeed 39.9F, the correct conversion is F=(9/5)C +32
This is great! I would like to see a LTD engine that is under pressure and see how low of a temperature differential one could get with that. I know the record for an atm LTD engine is 0.5C by Dr. Senft...I wonder if a pressurized engine could get even lower.
did you use a regenerator? - Steel wool or something similar.

great job! did you use helium or is the working gas just air?
greetings from germany =)
Muy prolijo, muy lindo a la vista, donde va la fuente de calor??
is that a graphite bearing at the center?
What did you use to make a base, and cold and hot cylinder ?
hi, very great and nice work! Imho :)
Put propellers on the largest side to dry faster and it should increase the efficiency, right? ;)
Cheer.

if the stuff inside of the engine couldn't melt how fast would the engine turn with a candle or flame.
bueno very good
Its a spinny thing. Spinny things can turn generators, pumps and other various things. Just because the example is small does not meen its uses are.
Is there a clear wall around the perimeter?

Very veeery good, but where i can find instructions to do it? congrats!
@csizmarikg So you cut the credit card to size?
Could you explain precisely how to make the power piston?
Engine doesn't need heat. Engine can with temperature differential from wet paper.
Does it run faster if there's a larger temperature difference?
Your math was correct!
What is your power piston made of?
true, which is why i said the oops in your comment, I figured thats what you ment, but big difference in the phases of "Engine doesn't need heat" and "don't have to add additional heat" which is why i called it an "oops" just like my oops of the typeo of opps....lol anyway have a great day..
Where did you find the plans for this?
I am wanting to create one for a Top Hat...
Hahaha nice. The correcter has become the corrected. The human race can contemplate the wonders of the galaxy, but we struggle to convert from C to F.
Search TH-cam for LTD Stirling Engine...there are a couple how-to's out there. Might want to start with the soda can engine though. :)
@teslstirlputt
That's pretty funny because water freezes at 0ºc and 32ºf but magically 4.4ºc is way below freezing.
°C x 9/5 + 32 = °F
(°F - 32) x 5/9 = °C

Eviltech
why do you want to use 50 bar
@teslstirlputt i have a hard time beliveing that 4.4C is 7.92F when 0C = 32F
csizmarikg is correct with the 39.9F
Do you have any good .pdf guide for making one?
Width of the monitor?
how much torque has this
Does someone know if it work if we tilt the motor? For exemple: when the heat source is a parabolic dishes, the central point of this parabol constrained to tilt the motor.
Answer me asap,

How it make?
Todo muy lindo, la verdad no entendí nada, por que no explican de que se trata

I guess it depends on how you interpret his original question. I interpreted it as "How does the engine run without heat being added."
I could send the assembly process with the elements of composition to develop it in a class for children twelve years?
what is the ratio between the displacer and piston diameter??
+Brian O Dughaill Normally they all have a 4mm gap all the way around.
yes and no, i said what you said, and corrected the major opps in your comment of "Engine doesn't need heat"...
wrong, a stirling engine is a caloric engine or heat engine. meaning it works with a temperature differential (like you said) which means it works because of the conduction of energy(heat) from hot to cold... just because he added a cold "thing" (the wet paper) does not mean there is not a heat source, it just means the heat source is room temperature or ambient temperature but still a heat source.
Is it a Nitinol based motor?
No
Stirling. It works on the volume change of air with differing temperatures.
can you show how to make that
If anyone is worried about overheating one of these engines, sit it on a packet of frozen peas-it will spin backwards and you're not heating it.
4.4C is the differential...Not the temp its running at. Did you watch the same video I did?
Dammit, yeah i forgot that we were talking difference, sorry bout that :S
I wonder what a block of dry ice on top would do.
Is that a piece of ham?
this is just mocking me i tried to make one yesterday and now one today and both dont work under ideal conditions still really cool though
no he's right f=9/5c+32, look it up after all 0C = 32F
Если пид низ свичку а сверху льод то вин буде так бистро крутиться
So you basically just said the exact same thing I just did but more precisely and with slightly better grammar....
Derp, I see what you mean lol.
??? so you can use heat and cold sources!!!!!!
Yes. But if you use a cold source, the engine runs in reverse.
tat video was cut so many times
Yes, Tyler...what you said...isn't correct.
Tutorial? Lol
You should take your own advice.
First 4.4C is the differential...NOT the absolute value.
Do the math properly...although a differential can be found without it being so convoluted...I will help you.
27C = 80.6F and 31.4C = 88.52F
88.52F - 80.6F = 7.92F
The tempurature differential in Fahrenheit is...dun dun dun...7.92F
bravo ho visto il video, saresti cosi gentile a mandarmi il disegno con le misure?, lo vorrei realizzare.a; colacivincenzo@libero.it grazie
This isn't correct.
Table-top temperature 31.4 deg C? Where is the place? Inside an oven? Get real. Another BS video to attract viewers.
That's 88 F. Haven't you ever experienced summer without AC?
Do you have a video record of building? Id love to see it.
