There's a refrigeration technique that uses sound. It tunes a cavity in a way that all the high pressure is on one side and the low pressure on the other half. Like a standing wave.
If you try this experiment, you'll find that there's a "sweet spot" where you need to place the steel wool, about 1/3 of the way from the bottom. Moving it out of that position will reduce the sound level dramatically.
what a cool video! Thanks for showing the frequency with your phone, I was sure that sounded like 528 MHz but, since your phone showed it was like 568 or something.

I live in Alaska’s interior. My snowmachine (or snowmobile to other folks) will make that noise in the exhaust pipe when I turn the engine off in winter. Now I know why. Thanks, Lord James Orgill.
This piston is a lot like a passive radiator on a loudspeaker, with the heat oscillator acting like the primary loudspeaker driver. Attaching the piston to the system changes the tuning frequency based on parameters of the piston and its flywheel load - clearly the frequency is greatly reduced over the earlier open pipe or your flywheel would be spinning over 30,000rpm. Adding more mass to the flywheel would reduce the tuning frequency of the system further, much like adding mass to the cone of a passive radiator. In short, the attached piston system improves energy transfer at lower frequencies by lowering the resonance. This is the same way you get more bass out of passive radiator loudspeakers, except the primary driver may be driven at any frequency, not just the natural resonance frequency, so it becomes largely a matter of electrical efficiency. Ported and horn loudspeakers also operate on similar principles, using air oscillating in cavities instead of a piston to improve acoustic coupling to the open air.
Very cool! Very simile to assert a sterling cycle engine. I built a sterling cycle pump once from plans that I found somewhere I forget where. I will have to dig those up and do that again. That would make a cool video. Thanks for another cool action lab video, I'm not quite ready to be a Lord yet. 😁
You can do something similar with a blade of grass between your two thumbs (facing towards you and blowing between). Not thermal, but resistance and resonance of the blade of grass. It usually breaks if you blow too hard.

This gave me an idea, i had many complex and veried system when i was work for various "energy company" and in almost any case there is always heat to be disssipated Most common example wojld be electrical transformator, some produce around 6Mw of heat So i really think it is possible to use this acoustic process to take most of the heat and put it back to electricity For exampke
I love this channel and James and all the experiments. I always take interest in what he promotes. This time, it worries me a little about the negative feedback I have come across considering this specific promotion. All I can advise is, do your proper research before buying and don‘t shoot the messenger when things go wrong.
I suppose the term "landlord" in English has some similar background. I actually watched the ad this time because the concept is interesting. I won't be purchasing a square because it has no relevance to my life, but I did find that interesting!
Its a bit misleading, as there is no law that states that you become a laird purely by the fact of owning land. But at least they do plant trees for you :)
also if you made this setup bigger would it make a stronger faster motor? and if you add more herts per cycle will that change the motors power or speed in any way?
So fascinating. I've also been intrigued with the use of parabolics/fresnels with energy/heat storage. I wonder if these 2 ideas have been used together in a way to optimize the concept of stored heat to immediate electricity. I wish I was smarter, science is so interesting.
The most difficult part for me to believe is how fast the air can heat up (expand) and cool down (contract) in order to create this cycle of pressure waves that moves the piston this quickly. That's the part that is incredible to me.
Dude, this is awesome. How scalable would this be? Wonder if we can set something like this up with sunlight using a magnifying glass to heat it. Cover the engine side to keep it cool...perhaps connect a little turbine and use it as a charging station for batteries or to keep an LED light on. Dude, this just blew my mind. Thanks for this!
The problem with things like this is they produce very little power. Which leads to them not being efficient, especially at larger scale. Regular solar would be better at small scale. Compared to the power output even something like a small gas powered generator would be better.

Sterling engines do not rely on resonance, but require both a large piston to act as a heat sink, and also a smaller piston to transfer the power. As I recall off the top of my head.
Efficiency depends a lot on the design and the environment the engine is working in, however NASA did some cool research some years ago in hopes to use them onboard deep space probes as a power source by making the heating source the decay heat of a lump of plutonium (similar to the old Soviet RTGs but used to power a stirling engine instead of a thermocouple). For example one thing that came out of it is that if internally the engine contains high pressure helium it performs a lot better. For more info, look up radioisotope stirling generators
