A power generation apparatus includes a rocker arm having a first end and a second end and is mounted pivotally between the first end and the second end, wherein reciprocal movement of the first end between raised and lowered positions urges reciprocal movement of the second end between lowered and raised positions. A pulley apparatus couples the second end of the rocker arm to a drive member, wherein reciprocal movement of the second end of the rocker arm between its lowered and raised positions urges reciprocal rotation of the drive member between first and second positions. A transmission interacts between the drive member and the output shaft, wherein reciprocal rotation of the drive member between its first and second positions urges rotation of the output shaft in one direction.
