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.
JWST uses that technique. It would be fun to try to recreate it.
@@aelolul the company that makes cryogenic thermoacoustic chillers has a pretty neat presentation about it.
NightHawkInLight made a video on this, pretty cool
Not Like a standing wave, *IS* a standing wave.
@@arjundubhashi1 what company are you referring to? I want to know more.
That experiment with the heated steel wool producing that hum is fascinating the most interesting science looks like magic
Yeah, WTF!!! This guy has some cool science experiments. I would have loved that in school.
Everything looks like magic if you don’t understand it.
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.
It's an age old experiment lol
That looks a lot like a Sterling engine. I thought we were going to see an engine that converts sound pressure waves in air into motion.
Cause it is
@@dronemotionlab so it's not a thermo acoustic one, right? Just the plain old thermodynamic cycle.
But it is ot a Sterling engine, because it doesn't have a Seconds Piston.
@@janluy603 This is a thermal acoustic engine. Difference from Stirling engine is the "Regenerator".
@@afaqh2356 yes, but a regenerator ist not necessarily needed for a Stirling engine. The Second Piston is (i think)
I don't know how this guy never runs out of ideas... Brilliant ✨✨
I think he might have gotten this one from Bruce Yeany. A fantastic guy that does fun experiments on CZcams as well
He has a team behind him
Brain.
@@illogicmath no bro. It's simple physics.
@@Sceince_Vedas_are_the_Universe yeah, real simple.🤦♂️
Cool! Related to this, maybe you could make a video on the principle of acoustic air conditioning? Running also on heat and very efficient.
Very interesting concept, love the effort!
I'm trying to make a replica of it for my science teacher.

Probably on a much larger scale
Imagine how conservatory or expensive it will be I dont know if the stuff is cheap or expensive so
Your whole PC
@@abatanmurewa3009 bruv you're gonna burn all the gas out in a year
Dr Stone?
this was the best implementation of this ad ive seen yet!!
Wow. That is some bloody clever stuff, and you get a clever little heat engine out of it!
This may be your coolest video to date! This is awesome!
This kind of content is EXACTLY why CZcams was created! 👍
Your channel is too good. Love it!
NightHawkInLight has a nice ongoing video series about these thermoacoustic phenomena.
Thats so crazy that i made this just earlier this week and then you post a video about it! quite a nice coincidence
This is one of the best Action Lab videos I have seen in a while. 👍
Glad you liked it!
And your pretty Old ,
Thats saying something
Ooh this is a cool application of that effect. I remember learning abou this in a nighthawkinlight video
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.
Megahertz?
MHz? Huh?
I don't think even my dog can hear what you're saying
this guy is on the way to build a damn time machine soon 😳
You know he didn't invent any of the things he's demonstrating on this channel, right?
@@unvergebeneid yeah i know .. but the way he is getting deeper into science and clearing his knowledge he will someday invent something legendary lol 😆
@Penny Lane well he may not have invented anything he demonstrates but he did create a very successful CZcams channel with demonstrations pure genius
Using light
He has already done
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.
Absolutely fascinating!
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 is amazing!
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. 😁
*Stirling engine
This is a thermal acoustic engine. Difference from Stirling engine is the "Regenerator".
The science parts of this video were very interesting, James Orgill; thanks for sharing!
the science parts were! the part advertising a scam was not.
@@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 CZcams 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.
@@KX36: Yeah, it kind of makes me surprised that James didn't turn this one down.
Like a putt putt boat, awesome stuff, action lab!
This idea is genius!
Imagine making a car that runs on sound! Great video! Hopefully this will spark some genius for someone to make amazing things
So that when you honk to avert an accident, it speeds up. :-)
I've never been so interested in an ad before but being able to be called lord is actually kinda bad ass
Congratulations, Lord Action Lab!
🗡🧎🤴
That runs on heat🔥
Thanks for the amazing video "LordActionLab"
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.
Works with most flexible films, like plastic food wrap or shopping bag material.
Wow, the flaming version of this is very interesting!
Stirling would be proud.
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
Very clever!
Yup, in some ways this is similar to a Sterling engine, but there are some important differences.
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.
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.
No way!!! 🤯🤯🤯🤯 this is insane!!!
Yeah, I like that this air-over-the-tube-end thing is how whistles and pipe organs work.
Dude, seriously cool!
The first thing I imagined from the title was him powering the engine by saying encouraging words to it.
Hey Lord Orgill, if you ever visit that plot of land, you have got to show us in a video! Hope to see it!
That is freaking cool
Nice transition.
Congratulations, lord doctor Action Lab.
I swear you and I are in sync on so many topics. You have a great channel, and this was a very interesting video. - Lord Todd
Ikr
Lord of what
got your certificate Todd?
How are you in sync with him?
@@mnnglss_xstnc Literally nothing. The whole "souvenir land makes you a lord" thing is a total scam.
1:28 Just one moment . . . my television station has just gone off air.
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.
Amazing!
It's fascinating that it's a note I'm guessing that's to do with resonance but I find it mostly odd that its pitch changed but the note doesn't.
@Integza needs to build one of these!!
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 :)
Really nice demos on this video. As a Scot I was amazed at the choice of sponsor. (Not a legal conveyance of land by the way, just a bit of fun)
But is it true you can legally use the title please ?
@@andymouse It's false. You can't
Salutations Lord Mouse, in the UK we call such names 'assumed names'. For some purposes you can "Provided there is no intent to defraud or misrepresent, persons may use any name or style they choose." Yours faithfully, Lord Potter of Hogwarts
@@scotimages But you can call yourself that even without this junk. So why bother?
Dear Lord Mouse, on the more serious matter of the mechanical equivalent of heat, I have decided to confer on any person who can produce a rotory heat engine of at least 1/pi Carnot Efficiency the title of Lord Wizard of Mechnical Engineering. Such persons will thereafter be entitled to use the prenominl style Lord and the post-nominal Wiz. Mech. Eng. Final arbitration will be provided by Lord of The Action Lab.
wow AMAZING
1:26 for curious people. the frequency is 581 Hz for his setup
Now, that very good.
Congratulations! You made a fire alarm 🔥!
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.
Lord Action Lab!
How could you not give this guy a thumbs up!?
He is awesome.
Blew my mind
Science is dope no doubt
Thanks 👍😇💖....
Please explain the differences between this and a sterling motor?
No different
Time to change your channel name to "Lord Action Lab"
When he said this engine is powered by sound, I was imagining a car full of screaming people moving at 2 mph
One third of the way in, I was thinking this was gonna be an infovert for ear protection PPE.
This is black magic. I love it!
That's an LM song.
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?
its not legit, theres many. vids on it
Bro that heat test was literally hell on my ears 😭😭😭
Just looked up stuff about decibels and read that sounds above 85 DB are harmful, so yeah that sound is loud.
I love how he posts a video before i sleep💀💀
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.
Ooooookay!
Lord ActionLab 🤣🤣🤣
That's a wonderful little engine! Simpler than a Sterling motor. What would the turbine version look like? Thank you.
I'm just really love
Is there a way to do it in reverse where the hot end is cooled and the cold end is heated and it will still work as mechanically configured
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!
Trash can be fuel too
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.
Lord Dr Action Lab
Night Hawking light did a great video on this
Hail Lord Action Lab🥳🥳
Is this resonant sound wave engine more efficient than stirling engine?
I dint think so
That’s incredible how do you think of that!
He didn't he just explained it wonderfully he's a scientist.
@The Action Lab - Makes me wonder if you can use a few Thermoelectric Coolers (cooling pads) to produce the same results
What a way of mixing concepts in the communication......it made think of the old coffee houses the King of England "long ago " banned or tried to shut down
Being he could not stand the revolutionary sounds from the people.
These are nice sounds
Multiplying the affect of coffee
can possibly have a good impact
on our discussions
"Long live the King"
that can listen
Soon
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?
At about 1:30 in.... that looks like things plenty of people have gone to jail for.
What does it look like?
The physics way of remix a reel. Popular science hundreds of times. Lmao😂😂
im a glass blower and sometimes my torch flame will hit a hole at the right angle and itll start whistling. so it also works with fire
if we were to make one of these what ingredients/suplies would we need
Great cool down the planet by creating power to cool it.
In bosnia there is a cave underground a mountain even in summer its freezing can you make an episode of it why its cold
NightHawkinLight - Had this like years ago !!
whats the efficiency, is it at least comparable with stirling engine?
2 stroke Detroit engines also run on sound!!
wow cool, what power can produce? I guess it depends on temperature of heat
Sneaky Commercial at the end "lord" 😆 🤣 😂 😹 😆 🤣 😂 😹 😆 🤣 😂
What is the efficiency of converting heat to useful watts output? That would be very interesting. Is this more efficient than a typical TEM?
0.1 - about 43%
@@thisisajewtube cryptic.
WOW! Never knew about that particular energy conversion.
Now... what is the efficiency of it?
0.1% - 43%
The "quarter-wavelength" part caught my attention. That's also what you have to have in a rafio antenna. Coincidence? What's the connection there?
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)
