Abstract: Apparatus for producing electrical energy from the rise and fall of waves on a body of water. A vertical column is anchored to the floor of the body of water. A buoyant, spherical float is telescopically mounted to the vertical column in a manner that allows it to rise and fall with the waves, guided by the vertical column. A drive shaft is mounted to the vertical column and above the float. A downstroke drive transfer mechanism is mounted to the drive shaft. A first cable is attached to the float and to the downstroke drive transfer mechanism. A second cable is attached to a counter-weight and to the downstroke drive transfer mechanism. As the float falls as a wave trough passes, the downward motion of the float is transferred to the downstroke drive transfer mechanism through the first cable, causing the drive shaft to rotate. The drive shaft does not rotate as the float rises. The drive shaft is connected to an electrical energy generating system.
