Abstract: Two units sit side by side in a structure. The process is as follows: A bucket is filled with water from a water tray that has been filled with water from a water tank. The water tray signals the water tank when it needs water. When a bucket reaches a certain position, the unit bar tips water tray and the bucket receives the tray's water. The weight of the filled bucket causes it to drop to the water sewer below. The bucket dumps the water into the sewer. The water is pumped from the sewer to the water tank. The two units are attached by a sprocket cable at the unit bar, and the cable travels over three pulley wheels. Each pulley wheel connects with generating motors. The units are separated by a spiked pole. The units have a generator motor mounted on a unit bar. The movement of the bar and the motor along the spiked pole generates energy. The net effect is the three pulley motors and the two unit motors continuously generate power.
