Air Engine (PURE INNOVATION)

The engine can be printed at a massive scale, to power, let's say, a go kart. If you do power a go kart, post a make and I will do the same. But for now, you can make your own power source (e.g, a tiny A/C unit). It is ment to be connected to a chain and power wheels, on a small and large scale. This might be the next answer to mass produced car/truck engine, as an answer to ever-rising gas prices. Anyway, I will post pics later, so have fun powering your own car or something. Here is the chain to use for the gear: https://www.thingiverse.com/thing:2268154
