Hey Tom! Great build! Might I suggest using a pressure regulator to increase the efficiency of your engine by giving the engine a measured consistent dosage of air from the bottle? It should flatten the peak on that thrust curve into a nice long line. You already have a measured out volume, regulating the pressure will allow you to optimize every part of your design by guaranteeing a pretty steady rate of air moving through it (assuming the pressure doesn't drop so quick temperature changes are a consideration)

[@wilsjane]

The problem is that to find a smart design, you have to wade through dozens of idiots trying to scam us into believing that perpetual motion works. The ones who really won't give up are the guys trying to run an engine on hydrogen separated by electrolysis. A 30 second calculation shows that the energy taken to generate the hydrogen is at least 10 times more than it can produce. Simply disconnecting the tube and lighting the gas produces a flame smaller than a candle and we are expected to believe that this will power a car. Some of these guys have produced amazing fuel consumption improvements, totally oblivious to the fact that they were just turning down the fuel and the hydrogen was making no difference. The result was a 70hp engine producing 30hp and the life expectancy of the engine being reduced to a matter of hours.

[@aplustudios3622]

U can use a magnet(like poles)which will be more efficient. U will not need any air pressure. Replace the metal ball with a strong large surface area which must fixed at that position and another magnet of less surface area attached to the rotator. It should be very close to the fixed magent and all u need to do is to rotate the rotator and it will work unstoppable unless u stop it. Try this and compare it to your other engines.

[@ABaumstumpf]

If you pursue this design further - a small suggestion for prototyping that makes finding the correct length of the brass-insert and the push-rod a lot easier: Use screws. instead of just a random created brass-insert get a ~6mm brass threaded rod, make the fron smooth, and for the pushrod drill a hole and insert another screw/threaded rod into that hole. Like that you can just screw the part to a different position instead of having to make a new one every time. And for the gears - use some lego-gears (or any similar like Cobi, BlueBrix, Cada). The gears are cheap, easy to use, made from ABS and with the cross-shaft also easy to connect to other printed parts.

[@samuelmellars7855]

Hi friends

[@HomeGameCoder]

Very interesting iterations. I'm no engeneer but if I may, I will leave here my observations. 1 - The brass valve rubs inside the O ring. Doesn't that cause friction in a moment where the engine is deaccelerating? Maybe if you use a trflon tube instead brass you will decrease that friction. 2 - If you glue the pin and the valve they are fixed. Doesn't that make fine tunning dificult? Why not screw them? you can turn them sligtly to adjust exacly the moment to action and increase the performance without reprint everything again. 3 - The piston creates force in one direction only and need enough momentum to reach the next stage. Why not have two or three cilinders to compensate that and have the engine always producing force? I know it will consume more, but it shouldn't be just 3 times stronger... i guess it can be more. I would love to see a radial design... and the sound would be amazing! (sorry my bad english) Other note: print with thiner layers and more infill!

5:54 that look will never get old

"Yes I really did use Metric and Imperial in the same sentence" Laughs in Canadian/Scottish, tell me about it.

[@rodchallis8031]

Do you want the 12mm socket or the half inch? ;)

[@Crlarl]

Yeah. In Canada, we use 3 systems: USCS, SI and Imperial. Luckily, an imperial inch is the same as an American inch.

[@_aullik]

Now put 3 or 4 of those together and you should have a pretty smooth engine.

[@UNSCPILOT]

Given the design of the engine that might be possible, though a 2 cylinder version first might be good

[@vijaylal4404]

Why the people are giving this 👎 , instead of this 👍👍👍 , interested on your work❤️

[@daniellclary]

This is so cool to watch, and really shows how simple mechanics can evolve.

[@exacutor9]

6:04 it's adorable how excited you look when it starts working.

[@jonas1340]

"Thrust time per 2l bottle at 60psi" must be imperial, isn't it?

[@MrRishik123]

its better than imperial measurements. I propose its called 1 stanton. "how many stantons can that stanton cycle based air engine produce ? " is a question i want to hear eventually at a mechanical engineering lecture XD

[@ValentineC137]

It's worse, it's a mixture of Metric and imperial so noone understands what's happening

[@mickmuzzmkmz1628]

Lol

[@jamesmnguyen]

In this case the SI derived unit would be: N^2*m*s Or in SI base units: kg^2*m^3/s^3. Not very useful unless someone has a better way to represent the unit.

[@jimmytvfclassic]

Liter is metric, and PSI is imperial... so...

[@capnthepeafarmer]

I had those air hogs planes as a kid, there was also a big foam glider you could buy too. I decided to buy 4 air hogs and a glider to make myself a "B-17" style air hog plane. It was so strong it ripped the wings off 😂😂

[@Legg99]

Well done Tom. I've watched a good few of your video projects and many are just plain bonkers! But this is truly innovative. Nice one.

[@NateBaxley]

I love the look of pure joy on your face when the engine starts working correctly! Great video as always.

"noisy engines don't always go faster" rocket engines: am I a joke to you?

[@goldenoodles6281]

Rocket engines be: I am SPEEEEEEEEEEEEEEED!

[@yamayolochannel8733]

Turbo prop engines: yeah your kind of right

[@algebra358]

I hope you patented this design :) Pure R&D, beautiful!

[@primastanislaus9184]

Actually see this type of engine in my old Highschool science comp few years back, dunno if its the same concept using a diaphragm but it is using pressurised air. Fascinating stuff, almost like magic since I'm more of a social studies person.

[@nickhomer40]

Wow, these new renderings are absolutely beautiful Tom!

[@firstnamelastname9879]

it is fascinating to see how he does final year research projects every couple of weeks or so.

[@Ainmlas]

Hi friends

[@themorellonomicon2757]

Part of that is he doesn't need to write a hundred page essay detailing the prototypes and decisions and just shows some of them with one or two lines of text.
