Abstract : A power transmission device for transmitting electric power optically to remote locations. The device includes a laser for generating a laser light beam and a optical glass monofilament having a glass core and a outer cladding layer designed to convey the light beams directed into one end of said monofilament to the other and thereof. Means are provided for directing the laser beam into the receiving end for the monofilament at a predetermined angle which causes the light beam to exit from the other end of the monofilament at the same predetermined angle in a conical annulus of light. A conical reflector is disposed within the conical annulus of light exiting from the exit end of the fiber optical monofilament and has surfaces that intercepts the light beams within the conical annulus and reflects them along a different path. Disposed around the conical reflector is a plurality of photovoltaic cells in a position to intercept the reflected light beams and to convert the light beams to electric current. The photovoltaic cells are connected in series to increase the amount of voltage produced by the transmission device. Patent applications. (SDW)
