The whirl ventilator system includes housings to produce a whirling air flow rotating a fan to drive an alternator such that air flow from movement of the vehicle generates electricity to charge the batteries. The clutch system includes a clutch mechanism coupling a drive shaft and a driven shaft to impart a driving force to the wheels when the drive shaft is rotated faster than the driven shaft and to couple the driven shaft with a flywheel when the driven shaft is rotating faster than the drive shaft, the flywheel driving an alternator such that momentum of the vehicle causes the alternator to charge the batteries. The automatically operated, engine-generator unit is started to charge the batteries when the level of charge therein has dropped below a predetermined level and stopped when the charge level reaches a second predetermined level.Field of SearchIncluding traction motor of kind driven by expansible fluid from source external of motorWITH FLUID OR MECHANICAL MEANS TO ACCUMULATE ENERGY (I) DERIVED FROM MOTION OF VEHICLE OR (II) OBTAINED FROM OPERATION OF VEHICLE MOTOR, AND GIVE UP THE ENERGY (1) WHEN NEEDED FOR VEHICLE ACCELERATION OR (2) TO POWER AN AUXILIARY SYSTEM OF THE VEHICLE | |
