Ram air electrical generator/charging system

An air-driven power generating system for an electrically powered vehicle, comprising, in combination:

• at least one shaped ram air duct;
• at least one reduced diameter housing, fluidly connected to the at least one shaped ram air duct;
• at least one impeller rotatably mounted in the reduced-diameter housing, so as to be rotated by air passing through the at least one shaped ram air duct;
• the at least one shaped impeller operatively connected to a pulley drive system, having at least one impeller drive shaft and a pulley to rotate a main drive shaft having a first driven pulley/freewheel/gear-change combination unit, a second driven pulley and a flywheel secured thereon;
• at least one alternator, driven by the second driven pulley, and the flywheel to charge a battery system;
• and
• at least one by-pass channel formed around the at least one reduced-diameter housing, and connecting the at least one shaped ram air duct to an exhaust housing.

An air-driven power generating system for an electrically powered vehicle, comprising, in combination:

• a pair of shaped ram air ducts;
• a pair of shaped reduced-diameter housing, fluidly connected to the pair of shaped ram air ducts;
• a pair of shaped impellers rotatably mounted in the shaped, reduced-diameter housings, so as to be efficiently rotated by air passing through the pair of shaped ram air ducts and the pair of shaped, reduced-diameter housings;
• the pair of shaped impellers operatively connected to a pulley drive system, having a plurality of impeller drive shafts mounted on and held in bearings and which include at least one drive pulley having a belt drive to rotate a main drive shaft having a fist end and a second end with a first driven pulley/freewheel/gear-change combination unit at the first end, a second driven pulley at the second end, and a flywheel secured thereon;
• and
• a pair of alternators, driven by the second driven pulley, and the flywheel to charge a battery system.
