Abstract
A prismatic beam concentrator comprising two equilateral double prisms No. 1 and three equilateral double prisms No. 2 mounted above an expansion flow tube. The prisms receive two convergent incipient beams of diffused sunlight and emit a concentrated sheet beam onto the exterior wall of the expansion flow tube. An expansion flow tube is a straight elongate conical tube with an inlet orifice of minimum diameter (5 mm) and an outlet orifice of maximum diameter (25 mm). Water circulating through the tube is heated by the concentrated sheet beam. The warm water expands outward against the interior wall of the tube and deflects toward the outlet orifice, which is the direction of flow. The deflection of water in the direction of flow increases the rate of flow and decreases the pressure that need be applied by the pump.
