Abstract: The present invention provides a power generating system by two equal weights and or leaf springs for driving a vehicle and AC generator. This system includes two levers are be suspended by an U-joint for each lever, so each lever is free to move reciprocally to up and down. A weight with or without leaf springs installed to the long arm of each lever. Upon the movement of long arm of one lever from up to down, the short arm of this lever imparts rotary motion to a gearbox having an automatic transmission mechanism for imparting kenetic energy to the second lever through a mechanical linkage for lift the second lever's long arm from down to up and so on the reciprocative movement of the two levers is continuous on the running of the system. Two arms with two ratchet means can be used instead of said two levers.
