Abstract
Abstract Magnets are mounted on the undercarriage of a railroad vehicle and produce a magnetic field. Coils are mounted between the rails of a railroad track and extend in the same direction as the rails. The coils are positioned in the magnetic field generated by the magnets, so that as the magnetic field moves along the coils, it produces electrical energy in said coils. An electrically conductive output is electrically connected to the coils for deriving the electrical energy produced in the coils.

Claim 1
Independent Claim
179 words
A linear electric generating system powered by a railroad vehicle moving along a railroad track, said railroad vehicle having an undercarriage and wheels, said wheels rolling along the rails of the railroad track and said undercarriage being spaced above said rails and the area between said rails, said linear electric generating system comprising magnet means mounted on the undercarriage of the railroad vehicle and producing a magnetic field; coil means mounted between the rails and extending in the same direction as said rails, said coil means being positioned in the magnetic field generated by the magnet means whereby as the magnetic field moves along said coil means, said magnetic field produces electrical energy in said coil means, said coil means comprising a third rail of electrically non-conductive material equidistantly spaced between and substantially parallel to the rails of the railroad track, said third rail being electrically insulated from ground, and an electrically conductive coil wound on said third rail; and output conductive means electrically connected to the coil means for deriving the electrical energy produced in said coil means.
