Did it work?

The issue is scaling it, it loses potential the larger it gets with these it seems. More heat needed and its less effecient the bigger you get. Maybe a 100 or 200 cell large one made of smaller ones could do something but then way to many parts

Can u explain to me something, how the piston come back with the pressure forcing it to go foward

@@flaviomagyar8673 You speak Portuguese? If so, it's easier for me to explain.

@@ManualdoMotorStirling kkkk sim, n sabia q vc era br

@@flaviomagyar8673 Amigo, vou te explicar! Este motor funciona com a diferença de temperatura interna do ar, o pistão inicialmente pressiona o ar quente para lado frio e isso produz vácuo e na metade de seu curso o pistão é sugado pelo vácuo e depois ocorre ciclo inverso. Eu já fabriquei um motor semelhante a este em um vídeo que postei em 2018. Mas este motor em especifico do vídeo, não funciona não, isso é fake, primeiro que este modelo de motor com pistão único é muito fraco para rodar esses rolamentos normais que ele usou no vídeo e segundo com a dimensão do motor, jamais iria funcionar usando somente uma única vela como fonte de calor. Fora outras coisas que reparei no vídeo como o próprio pistão em madeira que não se consegue boa vedação que é necessário para um projeto como este. Nunca imaginei que um canal com a grandeza como este é, faria um vídeo falso. Mas tem outro vídeo no YT que também ganhou grandes repercussões e também é 100% falso, lamentável, tudo pela fama.

@@ManualdoMotorStirling também suspeitei que era falso, mas pq achei q ele funcionava de outra forma, vlw pela explicação

A stirling engine works by expanding when the gas is hot and compressing when the gas is cold. Traditional Stirling have a displacement piston for moving the air to the cold side before compression and to the hot side before expansion. This doesn't have a displacer ! So how does it work ? The key is the steel wool at the end (I think). It acts as a regenerator. One side is pretty cold, the one near the flame is hot. So when the piston moves left in compression, the gas moves further into the regenerator and cools down, which aids the compression. The opposite happens when the piston moves right and the gas expands out of the regenrator. It leaves the hot end and aides the expansion. But I suspect this is a little finnicky to get to work and the video may be fake.

​@@TaserFish-qn2xyi get the concept when piston moves left it is cooling down the regenerator, but im confused on why does it turn left and not just stay at right since the hot air pressure pushes the piston to the right?

​@@TaserFish-qn2xyalso, can the syringe tube and piston (corkscrew) parts be replaced with metal? i know that heat will distribute faster but maybe i can create a bridge between the heated parts and the piston using wood or such to establish heat difference, had a school project involving metal and 3d printing and i want to build this

@@artupaysivar6884 A few things make it keep spinning. 1. There is a flywheel/ rotating weight. Even if the hot air pressure keeps pushing to the right, the flywheel still has momentum and squishes the air back together. 2. As hot air gets pushed into the (relatively) colder regenerator, it cools and contracts, effectively "pulling" the piston.

@@artupaysivar6884 Well, it has to run smoothly and be mostly airtight. That's not a easy. In fact, this whole process quite finnicky. The size of the hole and amount of steel wool will also likely have to be tuned/ experimented with until it works. I'm not sure that metal on metal will run smooth enough and with small enough tolerances to make it work. Guess it depends how well it prints. And the syringe part being metal is really making it harder. The regenerator should be much colder on one side than on the other. If it's all in a metal cylinder, then that doesn't work. Mayyyyyybe you could make it work but I really don't recommend it. For such a simple project this is more than hard enough to get working without the metal. You're probably better off doing a typical Stirling engine with two pistons and two cylinders if you're working with metal. Alpha type for example. The benefit there is that the hot and cold side are separated. If it's all in the same metal cylinder it's harder to get a decent temperature difference. That is if you can actually make the pistons run smoothly and close enough to airtight. I'm not an expert, but I've wanted to build a Stirling engine for a while and I've got the theoretical background on it. Lemme know if I can help some more.

This is what's known as a beta type sterling engine. I don't know much about it myself, but at least you now know the name so you can look it up.

@@lukewest5397 the one with 2 pistons is a sigma??

ukposts.info/have/v-deo/n4GTZqmFbYuIzHU.html this video explains the 3 types od stirling engines

this is a beta type Stirling engine which has one piston and an air displacer in the tube to help cool air, and when the piston moves the displacer also has movement

I think you only need one but it will stall at low rpms

Plz tell

It looks like a graphite rod or something

Exactly it's a graphite of carbon for easy to move.

graphite ;)

@@Filippos_77 thanks bro

omg yea true bro, very noice

umm he goes into more detail here, ukposts.info/have/v-deo/oZmcZmuuqH-mp6M.html

Most likely to help hold a more consistent temperature in the hot side of the chamber

its quartz or borosilicate glass, normal glass breaks under these conditions.

carbon or graphite rod 😊

Yes: Wood, glass, steel wool, brass, wick, ball bearing, round rod, adhesive tape, glue

I wish so too

why do you need to prove Thermodynamics "law"

umm some redstone, iron ingot and some wooden planks! OH YEA and the cobble! ur welcome!

O primeiro a contar da esquerda é um cilindro de madeira com fita cola preta à volta e o outro é um cilindro de grafite, material que causa pouco atrito. Se esta a tentar fazer um Stirling engine eu n aconselhava este modelo, mas sim um vertical com diafragma (encontra tutoriais no UKposts)

it is graphite bro

Bro what is that black color thik lead

Glass syring or tube

i want to know the same

I think it doesn't matter. It just a part the the air pushes, it can probably be any material that high temperature doesn't alter.

Thats graphite

I think its graphite, because of the low friction???

yes

I could not fully understand it, you can write in Turkish

Yep, reverse Stirling cycle, there is at least one company making stirling refrigerators.

Most likely graphite, extreme heat tolerance and self lubricating so no need for oil

Do you know it yet?

graphite

@@liberman3929 What other material can we use instead of graphite? please reply urgently.

You can use two component epoxy putty to make the piston and then paint it on the outside with a normal graphite lead pencil.

@@PaterCurro is it the stuff you fix pipes with? I'm looking up for a science project and could really use some help lol

You're not with a science background, are you? I remember our teacher told us about this engine back in 11th grade..... It works by expanding and compressing air by heat...

@@animishaalagappa2327 I am from the Science background only, but there is only one Displacer/Power piston in this Stirling engine which makes me Wonder this way.

@@TheBiggestFloppa not tomorrow but yes, i have 1 week to do it. this one seems the easiest to make, so I want to make sure it works

@@alfarokator7242 ahahahahha. Just for interest, where are you from?

Same way your standard single stroke engine works

firstly when the piston is all the way in, most of the air is on the hot side, making it hotter and expanding the air witch pushes the piston. Then when the piston is all the way back, most of the air in the chamber is on the cold side, making it cool and "shrinking" it witch makes negative pressure and so the piston is sucked back in again. No, this is not fake. Yes, the energy comes from the heatenergy from the candle.

Go to a convience store in the ghetto and ask for a crack pipe.
