uniflo engine

thingiverse

The uniflo steam or compressed air engine is likely the simplest engine to construct due to its single moving component. Using reinforced 2L pop bottles, pressures of up to 1300 psi can be achieved, exceeding the standard 150 psi. If the compressed air RC market were to experience growth similar to that of AirHogs, utilizing this technology could be a viable option.
