The rice was a nice variation on a theme. At first I thought there would be more moving parts or more work to build it, but it turned out to be quite simple how it was constructed. I liked the simplicity.

I tried this engine when I saw the french video. I couldn't make it work I think because I only had old balloons that had a stiffened rubber, also I only had tomato cans and used corn instead of rice. I'll give it another try when I get the parts needed

This is pretty nifty. You should try make an alpha stirling engine that pushes two different shafts with magnets through two different coils

Isnt an audio speaker exactly the magnet in coil we are looking for for a linear generator?

Itcan be a bit simpler than that: Use a speaker of the right diameter as both the membrane and the generator.

nice clear instructions, Thanks.

❤Genius❤thank you for the inspiration rereliked❤

Thanks for sharing

Scaled up for steam trains (are some still around?) they'd sure save a lot of water.

How does this work😯

I'll make a separate video and will explain it. You can also read the following wiki page: en.wikipedia.org/wiki/Thermoacoustic_heat_engine

How long will the engine run before it stop, it be a good test.

Hi, Check the improved version of the engine which i made after this video, those engines can run for very long time, 10 minutes I have tested it and assumed that thermal equilibrium was achieved, which suggest they can run as long as you have fuel. the top part might need a heat sink to be kept cool if you run it for long time.

That video you were referring to is this one from 2016: kzread.info/dash/bejne/lWaO09eaqtXOhZM.html I just watched it a second ago while looking up videos on free piston Stirling engines and thermoacoustics. What does the rice do? Is there anything else that can be substituted for rice that would work? This is so bizarre. I am an enthusiast of Stirling engines and related engines, and I have never heard of such an engine as this 'rice' engine. Would this not work without the rice?

Hi, Thanks, I have added it in the description. Yes, we can replace the rice, I will talk about it in a separate video, actually rice is not a very good idea for long term operation, because it become soft and stick together and avoid free air movement. Also when soften it rots if stay there for long time. I just called it the rice engine, to get attention 🤣, it is a thermoacoustic engine. You can also watch another related video which i made: kzread.info/dron/XjrZ5omUWtR_mu62o5L9Wg.html

I don't think the rice on the top is a necessity. Apart from a small wad of steel wool, factory made engines are simply hollow.

It is very much necessary, this works with steam and the size is much larger than commercial engines sold on Ebay. Without that barrier it will not work or very very unlikely that you can get it work (you must chose proper size of pipe then)

Cool! Why it can jump up and down?🤔

How it works is a bit complex, i will explain it in another video. Meanwhile you can search for the term thermoacoustic heat engine

when the water is heated up, it turns to steam which builds up in the cavity of the can, that pressure builds up inside, then steam through the opening of the rubber it slowly escapes, fluxuating constantly in pressure variation inside the cavity of the can which makes the rubber start to oscillate/ move up and down as the steam escapes out through the rubber hole. basically, its pressure build ups in the can, then inflates rubber ballon, till it reaches a high enough internal pressure that forces the steam out the ballon hole, which then causes the ballon to be deflated and fall back, going and up and down in as many rate of speed as you desire, which depends on how much pressure of steam you introduce inside the can via how hot you get it with fire underneath. the principles of this is the rate of pressure steam that builds up inside the can, and the rate in which the steam pressure escapes through the opening is going to determine speed and power output. so the hoter the fire, the more the steam, the more the pressure, the more movement youll have.
