I've always wanted a paper engine that runs on a filled balloon, I am yet to find one, google doesn't help at all, I really want an engine that turns the force of the air pressure in the balloon to turn a crank, OH, another thing, i want the balloon to last for more than a few seconds, if you make this, I will pay what ever the price.
I've tried the engine in the link above before 3 separate times and the picture of the engine you put up is one I've been searching for for months.
This should get you going :-

I really, really like the idea of making a balloon powered engine. Cool!
Thanks for liking the idea, i just want a simple little engine that has a bit of skill involved so I can work on it for a few days.
I've not seen this before - are you sure it was Rob's site - does anybody recognise it - my children would love to make something like this
By the way, does anyone know where to find the paper steam engine on the following picture?
I found this a time ago on Rob's website. It's powered by air with a drinking straw.

There you can find the a paper steam engine, powered by a ballon.
Or the books by Kyle Wickware:
