An unbalanced gyroscopic apparatus is disclosed for producing
unidirectional thrust without having to interact with an external gas,
liquid, or solid mass. The technique is based on the controlled
transitions of an unbalanced spinning mass between two stable unbalanced
weight states resulting in a net unidirectional thrust at the spin axis.
In one existing embodiment, an apparatus with an attached body can be
propelled up a planar incline "sliding" uphill against terrestrial
gravity. In another embodiment, multiple pairs of synchronized and
mirror-image, unbalanced gyroscopic assemblies are combined as one
apparatus and attached to a body with the potential to propel it in any
direction, including defeating gravity completely without interaction with
gas, liquid, or solid mass or without use of propellants.
