A method and means to produce a force for propulsion comprises a source of electrons (100) and a means to produce electrons having a spatial velocity function having negative curvature; whereas, the gravitating body is compris ed of matter having a spatial velocity function having positive curvature where opposite curvatures provide a mutually repulsive force. Electrons having a spatial velocity function having negative curvature are produced by elastically scattering the electrons of an electron beam (113) from atoms at a specific energy. The emerging beam of electrons having a spatial velocity function having negative curvature experiences a force away from the Earth, and the beam (113) moves upward (away from the Earth). To use this invention for propulsion, the repulsive force of the electron beam (113) is transferre d to a negatively charged plate (121). The Coulombic repulsion between the bea m of electrons and the negatively charged plate causes the plate (121) (and anything connected to the plate) to lift. The craft is made to have angular momentum which is tilted relative to the axis defined by the gravitational force such that acceleration tangential to the surface of a gravitating body is achieved via conservation of the angular momentum.
