ALBUQUERQUE, N.M. — A mirror alignment measurement device, invented by Rich Diver, a researcher at Sandia National Laboratories, may soon make one of the most popular solar collector systems, parabolic troughs, more affordable and energy efficient.Diver’s new theoretical overlay photographic (TOP) technology is drawing interest from the solar industry because of its simplicity and the need to find solutions for global warming.
“TOP alignment could cure a significant problem with trough systems — inaccurate mirror alignment that prevents sunlight from precisely focusing on solar receivers,” Diver says. “Improperly aligned mirrors result in lost and wasted energy.”
