ABSTRACT:
A generator that utilizes the magnetic flux lines of the earth and includes a base, a frame that is attached to the base, a shaft that has a free end and is rotatably mounted in the frame, components for rotating the shaft, a plurality of brushes that are mounted on the frame, at least one ring that is affixed to the free end of the shaft and which is in rotatable contact with the plurality of brushes, and an armature that is formed by coils of wire which are wound around a rod that is attached to the shaft, the coils of wire have free ends which are connected to at least one ring so that when the armature rotates the coils of wire cut the magnetic flux lines of the earth and cause an electric current to be generated at the plurality of brushes.
