A generator for converting tidal fluctuation to electrical energy is provided. The generator includes at least a first energy transfer mechanism. The first energy transfer mechanism includes a weight that is floatable in water. The first energy transfer mechanism further includes a first driver gear and a coupling rod connecting the weight to the first driver gear. The coupling rod rotates the first driver gear when the weight rises or lowers while floating on the water. Therefore, linear vertical motion of the tides is converted into rotational motion. A rotor is rotated by the first driver gear when the first driver gear is rotated by the coupling rod.
