A dish-shaped mirror focuses sunlight onto a glass ball, which distributes it evenly onto an array of photovoltaic cells (Photo: Blake Coughenour/UA)
The "tracker" consists of a steel frame that ultimately will support eight mirrors, together generating enough electricity to power about four to five homes (Photo: Blake Coughenour/UA)

Borrowing technology from sophisticated telescope mirrors as well as high-efficiency solar cells used for space exploration, a group of students and researchers at the University of Arizona are putting the final touches on a novel power plant that promises to generate renewable energy twice as efficiently as standard solar panel technology with highly competitive costs and a very small environmental impact.
