Indeed. Imagine something like the flaps integza created attached to this device instead of the veins. If you could construct a living hinge connection to have them attached to the core ring instead of the housing with the flaps feeding down slots around the housing like the veins do in the Di Pietro. It would resolve the issue with high RPMs overcoming the ability of the springs/elastic to spring back in time for the next revolution.
A fantastic video, Rob! I really like this one! When I saw the rubber band, vane return spring, I could almost hear Joerg Sprave. "Today we use rubber bands as vane return springs. Let me show its features!"
Thank you Rob. ❤ Since Angelo didn't know how this works as a pump and you have that laser cutter device. And a wind turbine that drives an air pump directly able to compress to say 15 bar then any LPG tank can become a battery. Ps the big ones are less than a grand and are safe to 17 bar.
I saw it mate - the flaps are a nice idea - but my thought was the wear and tear must be terrible on the flaps and imagine having to replace the entire rotor - but i certainly liked it
Robert, thank you for your incredible videos! Your coverage of the air engine invented by Angelo Di Pietro is truly fascinating. I loved the design and believe without a doubt that it holds tremendous potential for the future.
Reminds me of Ralph Sarich (Australian) orbital ICE which did make it into cars but always was limited by the seals. As others have mentioned Integza and he used teflon which makes sense. André
Pretty cool to see a 3D printed Di Pietro motor! As far as I can tell, it's the only really successful (non turbine) rotory engine after the Wankel and vain motor. You mention being iffy about the valves, which I definitely agree with! From the images I've seen, it seems like the full production motor has a more open path to the central chamber but it's also longer, which would be lossy as well.
I like the idea of turning air pressure into rotary motion this way. Put a flywheel on this and a little generator on the flywheel, and you could pump this from simple lantern bellows powered by a back-and-forth wind capture device, even a sapling waving in the wind. A pneumatic system gives you a lot of flexibility -- multiple units off one wind power source, or multiple bellows pumping air into one air engine to spin up the flywheel, and it's all pretty mechanically simple.
Interesting, but I don't think gluing rubber bands to the surface will last long, possibly why we didn't get a demonstration. Nice concept though, certainly appreciated.
Huge fan of the Tesla Turbine, I bought a machined metal 4" version from China for about $100, it runs to extreme RPM on air pressure, it also runs well on steam pressure. I've found the sweet spot is around 80-90psi
I basically clicked on this vid because of the motor.. I remember seeing Angelo Di Pietro showing off his motor on Beyond 2000 back in the day (i did think it was before 1999 though) ..
Oh My Goodness that's Another Awesome Project for me to Get Started over the Christmas holidays!! WooHoooooo!!!!🎉 Thank you very much Robert for your encouragement, enthusiasm and inspiration!!! I hope you have a have a nice Christmas with your Family around You!! Sending Hugs 🤗💞 Andréa and Critters. .. XxX...
This looks interesting. I just got a elegoo Neptune 4 plus. I’m currently tinkercading a 5 cylinder rotary air engine coming along good. I think I’ll try this one next.
What an interesting design, and another fantastic video. I wonder if this might inspire a workable internal combustion engine..? Hmm, cycle, lubrication... can't be having exhaust going through the middle unless it's a 2 stroke. Possibly a silly notion, more thought.
We all know Robert well enough to know he's not just going to play with it, he's going to attempt to 'improve' the design - and he already has some ideas! lol
Really cool rob I see what you mean about the values.. They could be more efficiently lain out. On an entirely different note though, have you have of Diamene? I'd love to see your input, ideally homebrew version of it.
That was my thought mate and I have been pondering - i have an idea or two I want to try - I have heard of diamene but i don't do that much chemistry now I have given up the lab I am afraid
Nah, this is a good low-speed 'turbine', no need to complicated it. Redesign ing for the sudden pressure changes would be a pain, external combustion means no redesign needed. ;)
Wow, very nice, i aways wondered how this engine works exactly. How did you come across the design Rob, did you just look at photos or something? Cheers
@@ThinkingandTinkering It is? Humm. Perhaps it's the principle of internal combustion that's simple as opposed to the implementation. Have you tried the engine? Integza (UA-camr) is actively looking for exactly this kind of solution because he's in competition with another UA-camr.
I hope all is well with you sir. I don't see much videos in the workshop anymore, is everything okay? I hope that you have a good Christmas, I know it'll be hard. It was hard (and still is) when my mom passed away in 2021. Just always remember that Jesus Christ Almighty God loves you and that our loved ones would want us to keep on keeping on. 🤗 🤗 🤗 🤗 Merry Christmas and Happy New Year and Jesus Christ Almighty God bless and protect you and your family forever and always in Jesus name Amen
Integza made an interesting design where he printed "flaps" on the rotor vs the veins. I thought it was particularly clever and simple.
I saw it - something similar might work well here
Yep- I was gonna mention that too- it did work better than he expected for the minor changes to the design.
Came here to say the same
yeah true, and my comment didnt make it to win that printer lol

I rate you amongst the best of UA-cam educators. Loved that.
oh wow - cheers mate
Best content on UA-cam.
wow - cheers mate
I love your enthusiasm for these projects, it inspires me to work on mine.
awesome - cheers mate
A fantastic video, Rob! I really like this one! When I saw the rubber band, vane return spring, I could almost hear Joerg Sprave. "Today we use rubber bands as vane return springs. Let me show its features!"
Man I have waited for this for years. I can't tell you how long I have been waiting for this
awesome mate - glad you liked it
Thank you Rob. ❤ Since Angelo didn't know how this works as a pump and you have that laser cutter device. And a wind turbine that drives an air pump directly able to compress to say 15 bar then any LPG tank can become a battery. Ps the big ones are less than a grand and are safe to 17 bar.
that strikes me as a pretty reasonable price mate
Nice Rob, you should check out Integza's solution he just posted on this type of air engine! It doesn't require any rubber bands!
I saw it mate - the flaps are a nice idea - but my thought was the wear and tear must be terrible on the flaps and imagine having to replace the entire rotor - but i certainly liked it
Cool! I was wondering what we missed!
sorry about that mate - for some reason the editing program deleted that clip
@@ThinkingandTinkering Hey, man, it's all good! It only matters because your videos are so awesome! Thanks for making great content!
This is an epitome of extraordinary. Therefore it must be put immediately into a museum.
cheers mate
I hated school as a kid, if Rob was teaching I wouldn't want to go home.
I agree mate, best teacher ever👍
oh wow - cheers mate
Inspiration is a gift.
Thank you.
Wow, thank you
Beautiful work. Thank you 1000 times over
Wow, thank you!
Thank you for this, I was waiting many years for a video on the di pietro motor!!
Glad it was helpful!
Robert: Your explanation is focused and concrete. Thank you!
I am surprised I haven't subbed till this moment.
cheers mate and thank you for subscribing
Wonderful stuff again Rob.👌
Glad you enjoyed it
Robert, thank you for your incredible videos! Your coverage of the air engine invented by Angelo Di Pietro is truly fascinating. I loved the design and believe without a doubt that it holds tremendous potential for the future.
I agree mate
Kudos to Di Pietro for inventing this and to you for demonstrating it.
I see that the rubber-band is a meme now 🙂
lol - what's not to like about a rubber band mate lol

Thank you Robert for the ideas. 👍💪✌
My pleasure!

What a great design, certainly gets you thinking 👍
Interesting, but I don't think gluing rubber bands to the surface will last long, possibly why we didn't get a demonstration. Nice concept though, certainly appreciated.
It certainly does!
no it won't last long you could always put springs in if you want but the main point of the vid was to explore how the engine works
My condolences regarding the lady in the picture
Thank you very much for that it really is well appreciated

nice - i have seen them - i am so tempted myself lol
Note they do high speed but not a lot of torque for their size.
I basically clicked on this vid because of the motor.. I remember seeing Angelo Di Pietro showing off his motor on Beyond 2000 back in the day (i did think it was before 1999 though) ..
I believe that was the date of his first prototype full engine
You should get yourself an AnyCubic Photon M3 Max. Resin printing for better quality, and super high resolution prints. Love your channel!!

Pretty neat 👏
cheers mate
Since central cylinder doesn't have to rotate, I think that vanes, housing and central cylinder could become one part using compliant joints.
you know i was thinking that - i was pondering printing a unit out of TPU of something similar
The Fred dibnha of gadgets is rob. Top guy big fan from Scotland
lol- cheers mate
What an interesting design, and another fantastic video.

awesome - cheers mate
We all know Robert well enough to know he's not just going to play with it, he's going to attempt to 'improve' the design - and he already has some ideas! lol
lol - curses I am an open book lol - the valves worry me - and the vanes i don't like it that they can leak air lol
I was thinking to mediate the leakage use felt gaskets.
nice one
Really cool rob
I see what you mean about the values.. They could be more efficiently lain out.
On an entirely different note though, have you have of Diamene? I'd love to see your input, ideally homebrew version of it.
That was my thought mate and I have been pondering - i have an idea or two I want to try - I have heard of diamene but i don't do that much chemistry now I have given up the lab I am afraid
I cant come up with a clever comment, so I'll support you by typing Ni !
I just appreciate hearing from you mate - cheers and all the best
coincidentally posted after the integza video.
Might make a good 2 stroke engine
yes it would!
Nah, this is a good low-speed 'turbine', no need to complicated it. Redesign ing for the sudden pressure changes would be a pain, external combustion means no redesign needed. ;)
Wow, very nice, i aways wondered how this engine works exactly. How did you come across the design Rob, did you just look at photos or something?

I looked at the patents mate
This is top!
cheers mate
Are there any rotary engines that actually deal with the sealing issues?
We've got a three way competition with integra, stanton and robert. we'll be going transatlantic with power from two coke bottles in no time.
I have seen both Tom's and Intergza's videos - I am not sure I am in competition - but it is fun lol
So how do you test the di pietro vs the vane motor? Just use two soda bottles pressurized to the same pressure and see which engine runs longer?
I would think probably a prony brake to measure static and dynamic torque - graph them and extrapolate the curves - that would be my guess
Something spiral or vortex in the guts might get her going faster.
give it a go mate
😊
cheers mate
Complicáted😂
really?
This seems rather complicated.
tbh it's less complicated than an internal combustion engine
@@ThinkingandTinkering It is? Humm. Perhaps it's the principle of internal combustion that's simple as opposed to the implementation. Have you tried the engine? Integza (UA-camr) is actively looking for exactly this kind of solution because he's in competition with another UA-camr.
Not meaning to be rude but Wankel comes to mind.
lol - Di Pietro worked on he wankel engine - and he says it was an inspiration to him
It is really nice to se a DIY vesion of this, some how "mythical" engine, but did I mis the test ?😊
there was no test mate - this is a demo model to get the idea of how it works - it needs some upgrades before a test run can be made
the informations are amazing. could you please make a video about the wind generator you make using speaker? best regards
cheers mate and sure
@@ThinkingandTinkering thanks a lot.
I hope all is well with you sir. I don't see much videos in the workshop anymore, is everything okay? I hope that you have a good Christmas, I know it'll be hard.
