pneumatic (adj.) - containing or operating by air or gas under pressure

I am gratefully accepting contributions to advance pneumatic technologies. I have created my first prototype "Little" motor, have open sourced my valve design, and urge others to help to build an air powered world.

Check out my GoFundMe Air Power Research campaign to help the cause!

Even the local FOX news station has reported on the pneubike.
