NOVELTY - The present invention is applicable in the field of electricity generation, it may be used for producing rotary motion in general, when connected to the equipment to be rotated. The quantity of weights or liquids is lifted to the heights of tanks through the buoyancy nature. The rotary motion will be developed by dropping them on the mechanism because of the gravitation force of the weights. This can be implemented to mechanism with standing limits for best results. This invention relates in particular producing rotary motion from the force caused by the impact of a weighted material moved to the top of a tank having a liquid and made to fall on a prefabricated network of conveyor and lever mechanism having one or more. The weighted material is placed in a container in a particular fashion and the container is of such a nature that it tends to float when immersed in a liquid, when the number of containers along with this weighted materials is placed in the bottom of the tank filled with the liquid, container tends to go up and float. As they come up with a force and on coming to the surface, the weighted materials get detached from containers (or along with the weighted materials) and falls on the above network mechanism, which transforms the impact of the fall into a rotary motion with the help a system of gears. The containers along with the weighted materials is made to go through at least one or more tubes fitted at the bottom of the tank with the help of specially made push mechanism (slope way, oil based mud, magnetic motor and floating container with water circular motion, water lever maintenance technology and wind-mill), empty containers, gravitational force and through pulleys, water pressure created by nozzle, water pressure direction support system. The tube is located at the bottom and fitted with a special non-return valve, so that the liquid inside does not come out through the tube, but at the same time allow the container having the weighted materials. The containers on coming to the surface of the liquid get detached (or along with the container) from this weighted materials are falling on a prefabricated one or more path ways go to the bottom of tank because of gravity. The weighted materials after detaching from the containers and falling on the mechanism, return to the bottom of the tank through prefabricated one or more path ways on its own because of gravity and get into the input slope way and this functions as above is repeated continuously and thereby at the gear system a continuous rotary motion is produced. The weight in container can be detached form container or the containers can be carried along with weights on the conveyor (without detaching). 2. The containers can be used with link or without link for best result. 3. A material floating in water, is used instead of container. To get more support for this the pendulum system can be utilized as per required. 5. By placing one more nozzles at the water tank. Water will fall forcedly, this force is utilized for better result. The water is filled using the water lifting systems. 6. Pressure creating technology can be used at the water. 7. For maintaining the speed in mechanism whenever required, another source of energy (Example -petrol, steam, solar etc) can also used as per requirement. Image 0/0
