Abstract

Abstract A battery powered automobile includes an air operated turbine fed by front and side air scoops for providing both charging current to the batteries and driving power for the automobile. An auxiliary internal combustion engine is included for use when necessary. Deceleration and wind sensitive controls operate door structure on the front air scoop so that it opens, increasing drag, only under predetermined conditions. Braking energy is utilized to help charge the batteries.
