This old project was an engine that I found laying around my room from maybe november. Anyway, lets get to some of the specs and features of the engine.

Specs:
Makes about 1/3 hp @ 180 rpm via air duster can.
Max torque from the air duster can supply is about 4 ft lbs.
It can make more than 1hp, you would need an air compressor to keep a steady supply of air though.

Features:
It uses a turbine to spin the internal gears.
Can be applied to a knex frame, so you can put it on a knex car.
Only needs a constant jet of air to run (at least 50 psi to get it truning at a decent speed; say 500 rpm)
Compact in size

Cons:
Does need lubed every now and then so it doesnt wear the rods down.
You have to be observant of how much torque you run on this engine.

The engine works by having the jet of air going into the opening, thus spinning the turbine, and that motion get torqued town to a 5.75:1 gear ratio, it the goes throug more gears, the black cog is the flywheel.
