All plastic is made?

Omg Im viewer 44444 :D

[xato909]

awesome

[MajorMIX]

I would like to make this motor, what do you inspired?

Do you have any plans, tips, additional information?

Maybe some pictures?

[MajorMIX]

@MajorMIX Already I found page Photologie.fr

But still do not know why the check valve.

This piece of glove on it is simply whether it is sticky?

[MajorMIX]

Why is this valve with a membrane?

This is a check-valve?

How does it work?

[AccessNo]

Awesome...gimme the drawings lol :)))

[richardebbole1]

you have a really great engine.  ignore these jerks.

[sukyake]

Nice engine!

It could recover energy from a car exaust... and charge a battery for hours! ^^

[BigAgitator]

bad ass!!

[SnowLeopardx88]

Great work, it is very smooth and silent, as well as neat looking and throwing out some high rpms there for a few degrees of difference. =D

[efahrenholz1]

They aren't useless for work. The original comment was made awhile back. The problem is LTD engines can't do large amounts of work. They are more for demonstration. It only shows the concept at work. Given more heat on this, you could belt the flywheel up to a small dc motor and produce a small amount of electricity.

If he used a piston that moved further and was a bit larger it would produce more torque.

[SWINGREGORY]

very beautiful

great LTD

[csizmarikg]

@SWINGREGORY Many thanks!

[efahrenholz1]

This is awesome, but you aren't showing a load on the system so it's just a fancy spinner in this state. You should post a video with a load so we can see the efficiency.

[csizmarikg]

@efahrenholz1

You are totally right!

This engine is only a model with very low Carnot efficiency (very low dT) and mW output range. But it can show the utilization of the small energy. Btw, the plants utilize only 1% of the solar radiation, however they can supply the whole Earth biosphere :).

Thanks for your comment!

@efahrenholz1

On my other video you can see a stirling alternator.

[aOa0a0]

@efahrenholz1

LTD engines aren't about "Power Output" ; as the temperature difference tends to zero, so does the available power.,

An engine running on VERY low temperature difference shows that the builder/designer of the engine knows what he's doing - it demonstrates a quality of build and an efficiency of cycle utilisation (thermal cycle)

that an engine with higher power output can easilly "mask"

LTD engines show the efficiency of the Designer/Builder more than of the engine!

v.good.

[efahrenholz1]

@aOa0a0 I agree, the engine is extremely efficient--but an engine is designed to do work. I'm not arguing your design at all here and I think being able to produce even a small amount of work from a minimal temperature difference is amazing. The only thing i'm stating is that LTD's useless for work, because it can't handle the load placed upon it unless you increase the temperature difference by a lot. It's more of an almost perpetual engine. Great job on the design though.

[gibbo1112]

@efahrenholz1 yea they are usless for work, so?

[csizmarikg]

@aOa0a0 Thank You!

[bmw2go11]

make a big version and hook it up to a generator..

[Aviator168]

Where did you get the graphite parts?

[valicoj]

how work the regenerator holes in the displacer ???

[csizmarikg]

@valicoj

Hello!

All the holes are filled and with cooking hood filter and glued.

[cromartie800]

@valicoj

They work by air going through them. The wire is heated and cooled during each cycle.

[EmperorOfMars]

I with I had the part and tool you had, the last stirling engine I made got smashed by a hammer

[ArmitronWearer]

its good to see someone getting innovative with the stirling engine. theres only a few people that build them on youtube apparently. i dont like seeing purchased items on youtube unless its a review. seeing someones work is always nice. great work. by the way your using a rubberized flap as the closed piston. why do you like that more than a cylindrical solid chamber? are there more benefits?

[amzamartell]

The graphite bearing is frictioning directly against the metal crank?

The ultra low LTD is dued to the low inertia momentum of the wheel and the low weighto of the displacer?

or are there aditional features that lead to the VERY low temperature differential?

[MrOlird]

Üdv!

Felregisztrálok az oldalra és nézelődök.

[csizmarikg]

@MrOlird

:), Üdvözlet a klubban!

(bár én nagyon keveset írok, de azért figyelemmel kísérem)

[giiraaf]

T. csizmarikg! Segíts kérlek egy ilyet csinálni! Méretezett rajzok, vagy arányok anyagok jótanácsok hiszen tudod! Köszönetteljes üdvözlettel: giiraaf

[csizmarikg]

Kedves giiraaf!

Javaslom, hogy nézd meg a magyar Stirling fórumot, ott részletes leírások vannak, illetve ennek a gépnek az adatai is:



[csizmarikg]

@giiraaf

Sajnos nem engedi a linket, de ha ráguglizol Infrared honlapjára, megtalálod.

Üdv

[bazengao]

its too bad that it hasn't enough power to warm up the water the supplies power to it! that way i might created a motion perprtuum engine

[cp4056]

Brilliant, do you have plans?

[mdUJHS]

Great work!

What is the improvement of the regenerator wholes compared to a solid disk? How does it work?

Again - fantastic work!

If you find the time I would like to see even some more details...

[csizmarikg]

thanks!

[csizmarikg]

Thanks!

[SuperBersuit]

Awesome engine. With this video, I love Stirling engines even more!

[csizmarikg]

Thank You!

[bg0821]

Nice build it moves quick. the graphite is a good choice for pistons, etc less friction and lightweight.

[csizmarikg]

Thank You!

You are completely right, simply I have no graphite material big enough.

[simi112]

Bravó! A világ legjobb LTD-je Senft után!

Szereinted mitől javult a legtöbbet? A grafit megvezetéstől, a regenerátortól, vagy az összes módosítástól? Milyen anyagból van a regenerátor? Mintha műanyag lenne?!

[csizmarikg]

Köszi!

Legtöbbet a regenerátortól, de a tömítettség és a kis súrlódás is rendkívül fontos.

A regenerátor konyhai szagelszívó filteréből készült.

[pali52]

It is a world record!!! 5*
