New solar field design to reduce heliostats

The new design proposes that the mirrors are arranged in a pattern similar to the spirals on the face of a sunflower. With this pattern, the researchers say, the land used for the solar field can be reduced by 20 %, because it is very compact. “Concentrated solar thermal energy needs huge areas,” Alexander Mitsos, Rockwell International Assistant Professor, says.
