Paper Air Engines

[lairdre]

Has anyone ever created one of these paper engines that run on air? Take a look at How To Make A Paper Single Cylinder Air Engine (Step-by-Step Tutorial) - YouTube

I have seen videos, but this is the first one I've seen that explains the process.

Thanks for sharing this, this is cool

Yes, thanks for sharing this, I love this kind of paper engineering. Ingenious! Could use this to make a balloon powered car, or other vehicle, good fun.

It's very clever and a great way of understanding how reciprocating piston engines work and the tolerances required. From a practical point of view it's totally unnecessary - since your air supply is already a continuous flow you can use it much more efficiently by driving a turbine!
