SOLAR - Solar power generation based on the design of sunflowers

a CSP installation is to make use of mirrors and lenses to harness solar energy and then concentrate the heat in a small area. Here, water gets heated and converts to steam. The steam is then used for running turbines, which generates electricity. Till date, the most efficient way of harnessing the maximum heat was to arrange mirrors and lenses on a tower in concentric circles.
florets on the flower are arranged in a spiral which is called the Fermat spiral or the parabolic spiral. The arrangement is such that that each floret forms an angle of 137.51 degrees relative to the next; called the golden angle.
These spirals are interconnected with each other along the Fibonacci series, which has been observed in branching plants, pine cones, seed heads and even in sea shells.
the researchers simply decided to copy the pattern of the sunflower florets and angled each mirror at an angle of 137 degrees relative to the other. The result was an increased efficiency.
