A gravity motor wherein a beam is pivotally mounted intermediate its opposite ends for oscillation in a vertical plane about a pivot point on a support structure. A moveable weight is slidably connected to the beam for reciprocal movement between the opposite ends of the beam past the pivot point. A drive unit is mounted and engaged for driving the weight back and forth between opposite ends of the beam thereby causing reciprocation of the beam about the pivot point by gravity to rotate a shaft in order to generate electricity or to provide other motor functions.
