Line-focus water treatment. View of a line-focus water detoxification plant. This system uses curved mirrors to form a parabolic trough which focuses sunlight onto a tube (white, top left) running above the mirrors. The intense sunlight directed onto the water is used to destroy harmful organisms and chemicals. Photographed at Sandia National Laboratories, USA.
