Would be very cool if there was a way to leverage kinetic energy for the purposes of pressure generation!

I'm making a modpack where progression follows kinetic > hydraulic > pneumatic and so it would be very cool to be able to implement the bridge between Create and PneumaticCraft via such a machine.

Like this one?

That's literally perfect ngl. I mean, I've since moved on from the project I was doing but this still fits exactly this interaction which is awesome.

Will look into it.

I would also love to see something like this. My modpack Tweaking Awesome features Create and Pneumatic Craft as the primary tech mods and if this feature is doable it would be some nice icing on the cake.
