Abstract: The design of Shaded Rotor devices to demonstrate the existence of a hypothetical Universal Particle Flux Field is presented. These devices should extract a measurable amount of energy from this Field. We believe the Universal Particle Flux Field can explain all invisible forces at a distance phenomena between masses, charged bodies, and magnetic materials. We propose that the Universal Particle Flux Field is a simultaneously convergent/divergent field, where the particle streams traverse to any point in the Universe from every other point in the Universe. The order of this Flux Field is a nearly perfect disorder, which is an order in itself. The strength of the gravitational component of this Field is conventionally denoted by “G”. Two neutral masses immersed in such Flux Field will develop forces between them, which are consistent with Newton's Equation of Gravitation. This Field is also consistent with Electrostatic, and Magnetic Force Equations.
