this is awesome. Even with that low wattage output, this is still a great generator. Think about it guys, A tea candle has an average of 40 watts of heat output for 4-5 hours. It would only take about 3 candles to rock this thing to charge your cellphone or tablet at only 1-3% efficiency !
nice job,, Iv only put together a small lamina engine so far but have been wondering how viable it would be to scale it up.. Now iv seen this i think i may have to have a go .. Great Work

@@1islam1 What the actual fuck are you talking about? This is an 8 year old comment about engines. And you're preaching your bullshit, sexist, violent, awful religion to me. Seriously. I know you're probably a bot, but fuck off. No human, let alone a bot, is going to convince me to worship a God who endorses Jihad, mass murder, ownership of women, and rape. Seriously, get a fucking life.
Hello, A marvellous achievement indeed, congratulations. Perhaps you could answer a couple of questions? You heat your cylinder on the end as is done on a regular stirling engine; yet all demonstration glass tube engines are heated near the middle of the cylinder. Would you mind explaining this? What kind of packing or regenerator do you use, if any? Have you measured the electrical power output of your engine? Thank you very much for your answers.
This is the largest thermoacoustic engine I have seen yet. Great job! What are you using for a stack or regenerator? Is there a restricting hole? Is the cold spot critical?
Great work against mechanical friction! -Have you measured actual temperatures yet? -Do you think that grooves on the piston walls are acting as gaseous piston rings? -Is the hot cap flat or filled with regenerator? -Is there empty space between regenerator and hot cap - like resonator space? I would try to increase thermal conduction on the hot cap and it´s internal surface area. There seemes to be no "glogging" with alternator - Is it with rotating PM´s without iron around coil or coils?
This is one of the best stirling engines designs I have ever seen on TH-cam. Could you provide more information like a section cut on a drawing with some rudimentary dimensions and explanation. I know the stroke and piston dia. but how does the rest come tiogether.
Is the piston made of graphite or tungsten carbide? The latter might be better in terms of tensile strength. If refractory properties are desired then you should use tantalum carbide
A thermoacoustic engine can theoretically run as fast as the standing acoustic wave it generates. Friction and inertia are the only thing which limit this.
Hey ScientificClo , Great vid of an even greater machine. Verry inspiring would really like to how manny amps the leds are drawing or what resistance they have so we could calculate power output and effienciencie. Does this engine have a restrictor ?? does it have a narrow hole between hot and cold side ?? If so, can you please give the dimensions. Last, does it run without crank or did you never tried this ?? Manny thnx for the vid !! Keep em coming !1
@ThePowertoolChef I don't think he is using any stack. A so called thermoacoustic engine essentially works like a 2 stroke engine with external combustion so the air in the cylinder is reused with some heat removed by the cold end. Power density is inversely to efficiency. The more heat removed by the cold end, the greater the power output and lower efficiency.
There is only one piston and no displacer www.stirlingengines.org.uk/thermo/lamina.html th-cam.com/video/owbjLWrC86g/w-d-xo.html demonstrates the internal power of the device near the end
Why power it electrically at all? If you already got that sorta..you can never get more than what you feed it in this version, whereas a fuel based is rather a conversion from heat to movement
Hi there, Are still online? because your last activity was some time ago. I´m doing research on the thermoacoustic engine because I want to take it to africa! so please let me know if you´re willing to have a serious exchange about it. Greetings V. Gyamfi (Name)
Nicely built engine, congrats. But a misleading video. You are putting more electrical energy in than would be needed to power the leds directly, the rest is wasted as heat. You should have said that, because some viewers may think that this is a good way of using electricity to power leds. It certainly isn't. At a rough guess, I reckon about 90% of the energy of the battery is being wasted as heat. The exercise is interesting and you've done it well, but maybe you should have been clearer about putting , say 100 watts in to get get 10 watts out.
@ScientificClo, have you tried to charge the gas in the cylinder to a higher pressure and see if you can get more power out of the engine? Have you measure the efficiency of the engine?
Nostalgic yeah, when youtube was still full of garage diy and still worth the watch!

OMFG! Finally someone built a large one. I'm trying to convert a 4-stroke to a high compression lamina flow engine.

This is the best engine I have seen. I am working on a similar design except that it works like a two stroke engine with external combustion.

Is there any chance we can develop the idea commercially?
Congratulations, for the workmanship of this engine. Please note that stating just the generated voltage is no indication of the power of the engine.
Couldn’t you use the output power to store power in some graphene battery to power the heater of the engine
First of all, extremely brilliant...hats off, truly...actually I want to make one after watching this...could u help me do that?
Explain the differences and similarities between the thermo acoustic engine and a sterling engine. Any uses for them.
Hi ScientificClo. Great work. Can you give an update on your engine?
A thermoacoustic engine can theoretically run as fast as the standing acoustic wave it generates. Friction and inertia are the only thing which limit this.
Excellent , congratulations. :)
what is the voltage/current output?
Hey ScientificClo ,
Great vid of an even greater machine. Verry inspiring would really like to how manny amps the leds are drawing or what resistance they have so we could calculate power output and effienciencie.
Does this engine have a restrictor ?? does it have a narrow hole between hot and cold side ?? If so, can you please give the dimensions.

Manny thnx for the vid !! Keep em coming !1
Really want one with an end that can be shoved in a campfire
i like that, do you have any plans available?
Do you have a diagram? Can you show us

it's a marvelous engine.Would you show the hot cylinder inside?
Very good! Congratulations!
Hi, I thought you were going to pursue another attempt at improving the engine?! And another video as I find your work inspiring ! Great job !
is this the same as a stirling engine? seems much more powerful than stirling engines i've seen. great job.
Not OP, but it's similar to a beta stirling engine but without the displacer. The air is displaced by acoustic waves in the cylinder.
can i purchase this model?
engine has a nice sound
How acoustic?
I wonder if there real life applications for this when the heat source is low/no cost, such as sun light, or the outside radiator of a household AC
Backyard fire pit generator
how this any different from a stirling?
There is only one piston and no displacer www.stirlingengines.org.uk/thermo/lamina.html
th-cam.com/video/owbjLWrC86g/w-d-xo.html demonstrates the internal power of the device near the end
100 watts ? ?

Looks more like a classic Sterling engine.

hello
Sorry, but this is not a thermoacoustic engine. You obviously don't know what a thermoacoustic engine is. This is just a conventional Stirling engine.
@ScientificClo, have you tried to charge the gas in the cylinder to a higher pressure and see if you can get more power out of the engine? Have you measure the efficiency of the engine?
