Abstract: The invention is a photon battery device for converting concentrated light into electricity. Daylight is focused into numerous individual optical waveguides which feeds the light into a Faraday Isolator which polarizes the light and prevents it from exiting the first end of the Faraday Isolator. At the second end, a large chamber collects the light where it passes a magnetic field to alter its polarization angle to prevent its reentry into the Faraday Isolator. At the second end of the large light confinement chamber the polarized light will be able to pass into the first end of a smaller light confinement chamber where a second magnetic force alters the angle of polarization so that the light will be able to be directed onto an array of optical waveguides which will focus the light onto a series of photovoltaic cells from which electricity emanates for use.

Abstract: An optical cavity device for converting concentrated light into electricity. The device includes an outlet compartment and a middle compartment. A passage connects the middle compartment and the outlet compartment together. A first shutter selectively opens and closes the passage. The middle compartment has an aperture that permits passage of outside light into the middle compartment where the light is concentrated. An inlet shutter permits selective opening and closing of the aperture in the middle compartment. A plurality of photoelectric cells for converting concentrated light into electricity are provided in the outlet compartment. Light is introduced into the middle compartment and permitted to continue to enter the middle compartment. Electricity is produced when a controlled quantity of light is allowed to pass from the middle compartment to the outlet compartment where the light is converted into electricity by the photoelectric cells.
