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.
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.

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 :)
@@Sceince_Vedas_are_the_Universe Experimentation is also required, our brain will not always correctly tell where the boundaries of law applicability are.
so yeah well done you have a propulsion method without external exhaist or moving partsz .. thats clean .. try under water (your engine is sideways vent a non round shape will help vector it
There IS external exhaust, it is an external combustion engine in this setup. You could use electric heating coils, or even a sound amplifier, I suppose, but would that be better than a normal electric motor? I suspect not, but it might have some special application.
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.
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?
that steam whistle looks very simple to make. in theory all you would need is a tube that you can heat up, A Fistful of wire, and a rag over one end. well you couldn't necessarily make an alternate history story with this as a point of divergence, it would be an interesting mention in passing.
Waves, whether EM waves or ocean waves, have same wave behaviour properties (ie. Constructive/destructive interference) and patterns i believe. Thats why it would be nice to find gravitational waves (for levitation tech) and imagine the implication of finding time waves! (Time travel)
Yes they are fairly efficient, but lack in torque. NASA made a sterling engine truck, so yeah they can be used for such things. They have a very fast piston operation, with speed comes less torque.
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.
@@KX36: The advertisement does seem rather silly, and I've seen it as a sponsorship of other videos that were otherwise good, hence my having specified "the science parts." Although I don't know that we can be 100% sure that the advertised service is really a scam, because I think James would have done his due diligence in researching it before advertising it. But maybe it still is one, and it seems like something that would be understandably thought as being the case.
@@HelloKittyFanMan. They just about skirt around the borderline of being illegal by officially claiming they are not in the business of selling Lordships. Officially, they say that this part is not their business and that their business is something different, but all their advertising is selling Lordships. They even give advice to customers about how to lie to DVLA to get "Lord" on your driving licence. The main claim that they make about being able to use a technicality in Scottish law to buy the title "Lord" is a scam. You can't buy 1 sq ft of Scotland to be called a Lord, and also they aren't really selling you any land, so both of those are lies to get your money - a scam. All they sell you is a worthless certificate, the same as buying a star. If you want to buy a Lordship, you have to do it the old fashioned way - by donating £2,000,000 to the Conservative Party. Unfortunately, he hasn't done any due diligence. Established Titles are having a big drive to sponsor EVERYONE on UA-cam at the moment. They must be paying a lot of money because I see 4 or 5 adverts for them each day from different channels.
@@tohfawalker159 he called it a "thermo acoustic engine" I believe they are very similar, but the expansion and contraction of the gasses happens at different points. I'm no Stirling engine master, but they have a few more moving parts.
The main difference is that the heat exchange between the cool and hot air is much faster and cause a short but fast air movement (vibration) instead of a long and slower movement.
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
Would it be more accurate to say this is an air engine rather than a sound engine?? From what I understand from this video, it takes advantage of air molecules switching state between hot and cold. The fact that it makes sound is just a by-product, right?
A quick question how efficient it would be using the sun and a lens for the heat part ? Not just efficient, isn't it cheaper that solar panels to go in that direction ? No maintenance needed, right ?
I'm sure focused sunlight could provide more than enough energy for the heating element. The main problems from it would be the cooling end becoming saturated with heat, and the piston needing regular maintenance due to moving parts. Basically it'd combine many of the problems of turbine engines and solar. Could still be worth it in some areas though!
@@polic72andDrD3ath The cooling aspect of the process is what I've forgot ! But that too can be overcome with the right set (I have some ideas linked to some "ancient" or Middle aged underground refrigerator concepts) that could provide the cooling necessary (a big waste of space but, science !) I think it's possible to make a sort of electric central using this concept to the very max But, you're right, the mechanical parts that were off with time is the ultimate issue that need to be addressed. Not sure I'll find some good idea to try delay that 🤔 Right now I'm looking at vacuum related stuff and lubricants to (maybe) find a better set but I'm far from it 😞
All the talk about electricity generation generally avoids the issue of how much energy it costs to manufacture the engine itself. This is true for the electric vs petrol engine debate too, most of a car's carbon footprint comes from the manufacturing and the best environmental thing to do is keep your existing car on the road But that (admitedly cool) engine will take milling, machining and just the metal alone will take vast sums of energy to create. The amount of aluminium in a soda can (½oz / 14g) - to make just that much uses the same electricity as running a hair dryer for an hour
Interesting! But is it really the sound what moves the piston? The resonance frequency of the sound wave is probably more than 500 Hz, while the engine runs at around 2000 rpm, which is 33Hz, far below the sound resonance. How is that possible?
Thank you for another awesome video! I saw your affiliate link for Established Titles and it looks like a cute way to support your channel, however is that title company actually legit?
I wish there was some way to funnel ambient sound waves, into a motor that converts it into useful work. Perhaps a giant lens. This could be the next big thing, instead of a room having only a giant TV, they could have 5 foot tall spherical lens funneling all the noise in the room to useful electricity, solving 2 problems, reducing annoying noise and energy footprint with only 1 gizmo.

@@yeroca Right. The glass has a natural resonant frequency, at which it will produce its highest amplitude vibration. If you tune the tube to its resonant frequency, this experiment should produce some interesting, possibly catastrophic, results.

It was found to be a scam. (The lord/laird part.)
Time to change your channel name to "Lord Action Lab"
Thank you very much
"its so deafening"
*was expecting to be earraped by a test tube*
Sneaky Commercial at the end "lord" 😆 🤣 😂 😹 😆 🤣 😂 😹 😆 🤣 😂
What if you use a test tube of a length that produces its own resonant frequency?
The length of the tube changes the pitch of the note it plays, but you need to adjust the position of the steel wool a bit when you change the length.
@@yeroca Right. The glass has a natural resonant frequency, at which it will produce its highest amplitude vibration. If you tune the tube to its resonant frequency, this experiment should produce some interesting, possibly catastrophic, results.
if we were to make one of these what ingredients/suplies would we need
How hot does it actually need to get, is it possible with certain geometry to reduce that requirement by a decent amount?
@Integza needs to build one of these!!
Dude, seriously cool!
Lord Action Lab! You are the cool lord.
I can do that by opening the 2 rear windows of my jeep at the same time. The pressure waves are fun.
This is amazing!
