Abstract: A hydraulic buoyancy kinetic energy apparatus includes a water tank filled with water and an air storage hood is merged in the water. Two buoys are movably connected to the two slippery pillars and a chain is connected with the two buoys via two chain wheels, two belt pulley sets and two engaged gears. One of the two gears drives a third chain wheel to drive an output shaft of an electric generating set. An air storage cylinder is connected with the water tank and air in the air storage cylinder can be pushed into the water tank to alternatively empty the two buoys which are alternatively moves up and down to drive the chain between the buoys and to activate the electric generating set.

Abstract: A hydraulic buoyancy kinetic energy apparatus includes two buoys which are located at an upper position and a lower position respectively. A chain is connected between the two buoys so as to alternatively move the two buoys. Water inside a water tank fills an air storage cylinder to push the air into the lower buoy to produce buoyancy to float upward, and the upper buoy gradually fills up with water to produce a gravitational force and to force air into air storage hood. Since air is introduced from an air duct into the air storage cylinder from the air storage hood, the two buoys are moved alternatively up and down to link an electric generating set as a motive power source for generating electric power.
