NOVELTY - The method involves computer operated and programmed opening and closing of the watergates present in a hollow chamber which is perpendicularly partitioned and filled with liquid. The hollow chamber is present between two round or oval pipes of different sizes fit into each other. The pipes are seized and connected by two or more chains during the dropping and lifting phase (work phase). The chain transfers the generated force to gear wheels and to axles for further use. The gear wheels and axles are in the housing which is filled with lifting liquid, and they are part of the liquid column.    USE - Used with e.g. weighting, hydroelectric plant.    ADVANTAGE - The method involves computer operated and programmed opening and closing of the watergates present in a hollow chamber which is perpendicularly partitioned and filled with liquid, and hence achieve a desired rotating speed. Through-flow openings and distances to each other enable movement of flotation liquid within the plant walls without big hindrance. A pollution free energy production is ensured.    DETAILED DESCRIPTION - The dropping and lifting body, is set free, and the chain seizes this dropping and lifting body and transports it to the starting point of the falling or lifting range from where the connection to the preceding body is searched to attach it to the pulling chain. A loss, noticeable by sensors, of liquid and air pressure within the upper discharge opening watergate area is adjusted immediately. Stopping of the plant and thus closing of the watergates, monitored by sensors, is possible for emergency or repair. The liquids are again delivered above the discharge opening watergate, so that the following lifting body is easily raised with the containers and the necessary quantity of lifting liquid remains. The lifting bodies contain inserted compensating reservoirs, which react with easy pressure changes in the lifting liquid and take up or deliver additional liquid quantities. The air-filled reservoirs have a connection with air contents of the lifting body. This connection can be opened or closed by mechanical or computer-operated valves. A connection of the liquid of the reservoirs and the main lifting liquid is provided. The liquid in the reservoirs is under spring-pressure or air pressure. Mechanical or computer-operated valves are provided for fast and coordinated closing and opening times. An INDEPENDENT CLAIM is also included for a device for use with e.g. weighting.
