Will Your Next Engine Be Air-Powered?

Recommended Posts

A 91-year-old Navy vet thinks he's got the solution to pollution: Air-powered (well, battery-powered) engines.


A specially-designed bank of rechargeable batteries provide power to a series of high pressure air compressors and air storage cylinders which are connected to air motors. Various sizes and types of such air motors are capable of generating propeller RPMs well in excess of speeds required to move watercraft. It sounds simple, because it is simple.

Get ready for your next repower.
