Here two Florence flasks are used.The oval shaped Florence flask is filled with water. It is closed air light along with a pipe A clamp is attached just above where the pipe and the pot shaped Florence flask are in contact. Because of pressure difference the water flows towards A through in the upward direction. Therefore the weight of increases and it moves downwards due to the gravitational force when it moves downwards the Gear attached to the shaft rotates thereby rotating the armature coil of the dynamo which is connected to the Gear which in turn produces current. Thus the current is produced throughout the day because of the downward and upward molecule of the shaft and gear due to the gravitational force.
