2030 An Air Engine Anyone Can Build

If you are interested n the STL files for the valve you can find them here www.thingivers...

What really makes these videos into treasures isn't the engineering-for-laypeople educational content, and it isn't the inventive shed tinkering. It's the fact that your reaction to things working is a friendly and almost grandfatherly version of the Mad Scientist (Engineer, really) Cackle of Triumph. You should be a fixture of US public television educational content. Thank god KZbin exists to pick up the slack.

[@bencapobianco2045]

I’m going to make some of these bellows for an off label use… cut it down the middle longways and make way covers for my lathe and mill. Thanks for the awesome idea as always!!

[@BillHallProductions]

I thought you were going to say you were making a bong out of the bellows

[@uscitizen5656]

Seeing this reminded me of the movie " The Great Escape"! They made a bellows to push air into the tunnels they made.

[@nitcat1]

Now you’ve got me whistling the song 😅

Spot on.

[@ferdinandheld5432]

Used to have an Lego Excavator with the same set-up to operate the three pneumatic pistons it had. One extra piston had a return-spring and was used as an air-pump. This was around 1984 or so.

[@daniellapain1576]

A possible way to make a water pump? The water flow can cause a syphon and get the bellows moving to push more pressure into a check valve maybe. Unsure really, but a Stirling run on bellows would be a great idea instead of a fan because you could stoke a flame and cool the cold side in one go.

[@royksk]

Looking at the beginning where the bellows are on the bench between your hands gives me an idea. You could dismantle a mouth organ and fit bits to the ends of the bellows to make a musical instrument. As you stretch the bellows air is taken in and then compressing the bellows would force air through the musical bits to make sounds. Needs a bit of work and a name then off to market in my new, Ford Concertina 🤪

[@AnonymousAnarchist2]

absolutly beautiful. Brillant way to display and teach.

[@archibaldvonkranski8881]

Robs one step away from strapping a windmill pump to the bellows😅. Great episode mate ❤ that osilating valve was an awesome build but the use of the bellows was super cool 😎. Concept well demonstrated 🤗

[@thetruenolan6655]

The 24V electric water valves used for sprinkler systems would also work for pressurized air or vacuum. Reed switches and magnets could trigger them, and by moving the magnets be easily adjustable for timing.

[@JohnSmith-qm5xu]

looks good, clever design adjustments. Works like a bellows in reverse. Newer take on older principles/design. Good stuff.

[@grendel1960a]

stunning and spectacular, a less spectacular valve is the simple flap valve, a flap of leather across the air intake (or outside the air exhaust) will allow the one way passage of air quite conveniently, once you have a valve you done even need bellows, 2 airtight bags will do (viking age forge bellows were essentially 2 animal stomachs or 2 leather bags and alternately pushed and pulled (a handle was attached to each for the pushing and pulling)

[@ogi22]

Yes, flap valve setup is as old as bellows and it is very, very simple/reliable/time tested. But it's Robert. The tinkerer. He did it for fun and science! 🥰

[@ktm42080]

Great video! Thanks for inspiring us to think and experiment. I had teachers, back in the olden days, that would do similar things to motivate us to use our minds and turn off the TV.

[@peterfelecan3639]

Those were the days, without 3D printing. Same fun even if more klunky.

[@Warp9pnt9]

Another channel I watch is "Primitive Technology", about an Australian that makes all technology by hand as a hobby, mostly stone, ceramic, and some crude iron smelting and forging. He uses a rotary style bellows. I wonder about the performance and efficiency of energy conversion of the two bellows styles, comparing energy in vs energy out, ease of construction, and so on. Talk about using "old" technology for inspiration. With a rotary bellows, I think there might be less energy loss in converting energy in the first stage of mechanical to air pressure. Depends upon the source of mechanical energy. A linear piston might to better with a linear bellows, connected by rods or lever, whereas a rotary/impeller style bellows might do better with something like a bicycle, pulleys and belts, to make better use of human energy via legs as opposed to arms, for instance.

[@hunnybunnysheavymetalmusic6542]

Referring the tiny printed bellows you posted in another video released on T'n'T, this could be used as a motor to drive a little lift pump to move water up a hill at a level of pressure greater than the pressure of the falling water [but slowly, of course].

[@travismoore7849]

I Made a air engine from a electric clock motor and straw, The part of the motor was two steel wheels with some flat pieces on the sides, It was in a housing and worked like a small air turbine when I blowed on it. It was a fun little toy but I never did anything with it.

[@dav1dbone]

There's a guy who printed off a Deltic model engine, amazingly just turning it over without compression it sounded just like the real thing, an air engine based on that would be great.

[@wildeslothe5475]

7:05 Robert's famous laugh.

[@chriskeeble]

I am still learning all the time from your videos, Rob - and I'm closer to 100 than birth! ;-)

[@WayneCarolan]

A spring return on one side of the bellow and used in a high traffic area would be for sure be interesting.

[@donniewatson9120]

I saw an interesting stirling engine that had bellows and a rotor. The rotor was a half-circle rotor for the hot side and the bellows was used on the cold end. It was an odd setup, but it worked.

[@RoofAndAMeal4UsAll]

Wonderful! How might those bellows hold up to heat? A high temperature bellows that would not wear quickly would be awesome. Thank you for your work Mr. Murray-Smith!

[@MountainCatBob]

Energy transmission by air pressure could be nearly 100% efficient where copper loses significant power in low voltage DC. Bellows are more fun than I ever imagined! Thanks -- Will definitely check out the Bellows series.

[@Kangsteri]

You could scale this to something very big too. The myth busters tested the vacuum cleaner motor for human size elevator ;)

[@fss1704]

that looks like it was made for other thing, like an automatic schlong

[@nic6754]

Always love your vids guys. Only subscribed at I think around vid 1800. But like how you weirdly fall in love with the characters from your favourite TV shows, I now laugh a little every time you do Rob. Love it how you laugh when you see your things working ❤ Keep em coming guys. Thank you for the awesome content 😊

[@tenlittleindians]

Have you seen the movie "Sam Whiskey" where the blacksmith builds an air pump for underwater diving? Your motor looks a lot like his hand operated air pump. It's a great western movie with an all Star cast.

[@DABrock-author]

I was thinking along the same lines. It reminded me of drawings I’ve seen of the air pumps used in the tunnels of Stalag Luft 3 for the ‘Great Escape’. (The actual event, not the movie version)

[@tenlittleindians]

@@DABrock-author Yes, it looks like those too!

[@colleenforrest7936]

So we could work this in reverse, to compress air? The issue I can see being that as the pressure grows, any weak spot becomes more likely to blow... 🤔

[@Xayuap]

for compression you can just check valve

[@RandyCampbell-fk3pf]

Liquid nitrogen costs as little as $0.15/liter. Not only would it be better for the moving parts of the air motor, but with minimal capital investment could be scaled for distribution with useful byproducts like liquid oxygen and dry ice. All you'd need is an insulated storage pressure vessel with pressure relief and an uninsulated expansion chamber to allow ambient temperature (even in Nome, Alaska) to provide the pressure.

[@colrodrick8784]

Ta Robert. Amazing stuff you do.

[@johnmcginnis5201]

The air engine reminds me of a scene from the movie The Great Escape.

[@mrpants8976]

that way you made it auto change directions made me think about the waggle generator that you made that looked like cattails that swayed in the wind

[@johnrussell4125]

The bellows design remind me of the bellows used in the 1960's film "The Great Escape"

[@benshithero3037]

Might not seem useful for anything but what about moving air from a rocket stove. But if you circulate air from pipes going through a rocket stove in and out the tent completely separated from the exhaust of the fire? Bet it even work with tin can an balloons sterling engine. Could make whole thing out of tim cans and balloons. Stove,, engine and valve/air circulation system. No fumes heat for tent while camping

[@maxvaessen]

Thanks for your continued inspirational videos❤

[@snowwhitehair485]

This motor reminds me of the pneumatic motors used on some pipe organs to remotely operate the stop sliders.

[@boblow2186]

Nice HVLP pump - motor. Bob.

[@quietparadise]

hopefully i'm far behind or out of touch (quite common in my universe) but you have hopefully seen the wind turbine driven pumps that are simply prop, shaft, eccentric between bellows with appropriate check valves. simple concept. the ones i saw were using airbags meant for suspension for a semi truck ("lorry"?)

[@kilokilos]

You have evolved into AI, no way I can keep up.😂🎉

Nothing new under the sun.

[@lawrencegt2229]

Have you been watching the Great Escape again Robert? That looks suspiciously like the device they used to ventilate their tunnels!😅

[@normandothegreat]

Great stuff as always! 😊👍

[@kadmow]

an air scaler / chisel/ hammer / etc in some iterations uses a similar valvular regulator - internally...

[@doriantinculas9396]

Hello ! What do you think of the Wells turbine? In principle such bidirectional oscillatory motion achieved by your air motor is similar to the motion induced by the "oscillating water column" used to convert wave energy into electrical energy.

[@Cryptic_Triptych]

Brilliant 👏

[@pgprentice]

If I remember correctly they had something like this in the movie "The Great Escape", to keep fresh air in the tunnel?

[@davidprocter3578]

not wishing to put the mockers on the project but that system of pipes and valve will reduce the efficiency of the bellows would it not be better to develop motors that work directly on the end of the bellows????

[@abdullahaliyuw]

Incredible!

[@steve64464]

Looks like them really old life support machines they used to have in hospitals 🙂

[@sandeepnaik6818]

How did you cut acrylic?

[@bringtheideas460]

Hey Robert. What do you mean the valve can be used for stirling engines? arent they valve-less?

[@hommerdalor6301]

Perfect to push a button. Repeat. :-)

[@BeefNEggs057]

What’s the goal? How do I know whether this video is relevant to me? Just a thought from a guy who wandered by out of curiosity and left because it’s too long without know what/why we’re building.

[@bethwilton8075]

[@CitizenSmith50]

2 bellows = overthinking it ! Use one with a return spring and simpler valve ?

Nifty " Air Motor" (I cannot call it an engine because no fuel is being burned)

[@magapefarmshomestead6453]

It's really not a motor either because no electricity is used. An automatic mechanical device maybe?

[@401ksolar]

@@magapefarmshomestead6453 research "air motor" or " hydraulic motor" or as in the case of this video, linear motor 😉

Add a set of tuned reeds and a keyboard producing a diatonic major scale to one set of bellows, and all you need is a bottle of rum and parrot. 😈🪗
