Abstract: A mobile system for treatment of a fluid containing organic material using sunlight may provide a trailer and a fluid treatment system mounted on the trailer. The fluid treatment system may include a solar tracking subsystem coupled to the trailer, a lens support mounted on the trailer and controlled by the solar tracking subsystem, a refracting lens coupled to the lens support, and a receiver mounted on the trailer. The receiver may be positioned with respect to the refracting lens to receive substantial concentrated light energy from the sunlight passing through the refracting lens. The fluid may be routed through the receiver for treatment of the organic material with concentrated sunlight.

Abstract: A system is provided for photo-processing of a material using incident light with an optical element that includes a plurality of concentric bands of optical prisms concentric around a focal axis. The system includes a target receiver positioned on the focal axis and holds the material to be photo-processed. The optical prisms concentrate incident light on the target receiver. The system may include a tracking assembly for orienting the optical element toward the source of the incident light. The optical prisms may be selected in accordance with Snell's Law of Refraction. The system may include a delivery mechanism for delivery of semisolid and granular material for processing.

The system includes a target receiver positioned on the focal axis and holds the material to be photo-processed. The optical prisms concentrate incident light on the target receiver. The optical element may be formed substantially of acrylic formulated to pass UV radiation. The optical element may include anti-reflective additives in the acrylic. The optical prisms may be fresnel zones.
