Inside the "strange engine" (transparent "wet thermoacoustic" or "rice" engine)

I made this transparent engine to see what's really going on inside and help figure out how it works.

I’ve built one using ceramic pellets from puffed animal (the ones you warm up) It worked great with alcohol as a working fluid.

[@peoplesresearchcenter6184]

Can you say what brand or where to purchase? Some types of heatable stuffed critters just contain flax seed or other material rather than ceramic pellets. Where did you find the ones with ceramic pellets?

[@humbertos.8430]

@@peoplesresearchcenter6184 the brand is "Aroma Home", from London. It was a gift from an European friend.

Thanks!

Awesome! 👀💥💯

You only need a tablespoon of water, and there should be a small space between the "rice" - membrane, and there should be an empty space under the "rice" between the "rice" - water. See loud test tube standing wave engine.

Thanks. I've tried search but cannot locate a video with that title.

@@peoplesresearchcenter6184 odysee ...

[@tibsim]

and on the side of the box above the "rice" you need a very, very, very small hole...

[@peoplesresearchcenter6184]

Instead of a permanent small hole there is the steam valve that can be opened or closed as needed.

[@tibsim]

@@peoplesresearchcenter6184 small hole is much better...

[@peoplesresearchcenter6184]

@thisisajewtube That may be, but if possible, I'm aiming for a completely sealed engine, possibly using a fluid with a lower boiling point. I've also run this engine with just a small hole without a valve and I don't see much, if any difference in overall performance.

[@tibsim]

@@peoplesresearchcenter6184 I think that the small hole does not take away from the performance, it just adjusts the center pressure, which is necessary for good operation. What effect would using a tube like the one on the metronome heat engine have? I think that two things working work in this machine, steam and air. A higher yield could therefore perhaps be achieved if we used a liquid with a higher boiling point, e.g. propylene glycol. I haven't tried it yet, only the lower boiling liquid.

[@peoplesresearchcenter6184]

Some interesting ideas. Might give them a try.

[@cesarcesar1961]

where can I find that valve?

[@peoplesresearchcenter6184]

I got that at the local hardware store. It is a "bleeder valve" for old cast iron steam heat radiators.

[@peoplesresearchcenter6184]

You could also try a plumbing supply outlet. Some don't have a special key but work with a screw driver and are less expensive. I see they are also available from Amazon: 1/8" MIPS Coin Key Radiator Air Vent Bleeder and Valve Key Plumbing Fitting a.co/d/32T1nXw
