Cheap Solar Concentrator for PV

“Article describes  a square piece of clear, molded acrylic about a centimeter thick which when beam of light shines a directly at its flat surface, a  green beam enters the acrylic and bends toward the center of the square. “If the process is repeated  at different points on the surface the beam darts toward the center.

Unlike existing designs, there’s no need for mirrors, complex optics, or chemicals to trap and manipulate the light. – Toronto-based Morgan Solar.”
