Abstract: I have designed and constructed three mechanical devices, each to generate asymmetrical centrifugal forces. Devices 1 and 2 generates asymmetrical centrifugal forces by varying the rotation radius of a mass, while device 3 generates asymmetrical centrifugal force by restricting the location of the rotating mass to one preferential part of the rotating path. These and similar devices are suggested for moving (transport) objects in any designed, predetermined direction of the 3D space in any penetrable medium like gas, fluid, vacuum, et cetera (ground, marine, air, spacecraft propulsion).
