ABSTRACT:
The invention is comprised of an electric motor and generator whose moving parts are connected to each other by torque-transmitting means so that the torque of the electric motor and the resistance of the electric generator operates to lift either the electric motor or generator for a distance against the force of gravity. The distance is determined by a mercury-type electric switch and the differences in gravity at different places above the Earth are measured both by a motor ampmeter and a generator ampmeter to detect minerals and water beneath the surface of the Earth.
