1. A power source powered by waves comprising, in combination, a frame having a plurality of pairs of legs extending into water and having a top member fixed to the upper ends of said legs, a horizontal shaft journalled in said frame above the water, a first pulley rotatably mounted on said shaft between each pair of said legs, a first releasable rachet mechanism preventing rotation of each of said first pulleys in a first direction, a non-releasable rachet in each of said first pulleys driving said shaft when each of said first pulleys is rotated in the other direction, a chain hanging over and engaging each of said first pulleys and having first and second ends, a first heavy weight fixed to the first end of each of said chains urging rotation of said first pulleys in the first direction, a float constrained to rise and fall on waves between each pair of legs, a second pulley rotatably mounted on each of said floats, said second pulleys each engaging the second end of one of said chains, a second releasable rachet mechanism on each of said second pulleys allowing rotation of said second pulleys when said floats on which said second pulleys are mounted rise on waves, a second lighter weight at the second end of each of said chains below said floats so that rising and falling of said floats raises said first weights, and means sumultaneously releasing both of said releasable rachet mechanisms associated with each of said first weights when said first weights are raised to a given height to drop said first weights and rotate said shaft by means of said non-releasable rachets, said means releasing said releasable rachet mechanisms allowing said releasable rachet mechanisms to engage when said first weights fall a given distance.
