Paper Abstract

A novel solar power plant utilizes concentrator modules that track the sun by elevation-tracking modules on azimuth-tracking frames floating in shallow water. The entire floating circular platform is flat and only knee-high. The circles can be closely packed to cover 83% of the land, unlike the low percentages of conventional wind-loaded tracking mirrors. Each elevation-tracking module has multiple TIR lenses, each of which focuses sunlight onto one end of a glass rod that has the solar cell glued to its other end. These rods kaleidoscopically homogenize the focused hotspot uniformly over the square cell. The cells are cooled by conduction to the water, and operate only 10°C above the water temperature. The cell voltage is near that of the hydrolysis of water, enabling fuel cells to produce electricity at night.
