Spontaneously rotating object for providing drive force, has rotary part located in sloping or vertical wall of liquid

摘要

The object (1) has one or more rotary parts partially located in a sloping or vertical wall (4) of a liquid (6) or in several walls of a tank (5) filled with liquid. The original Center of gravity (11) is shifted to a new position (12), creating a spontaneous rotary force, as described in Archemedes's law.
