US Teenager Discovers Fibonacci Secret and Constructs Solar Panel “Tree”

US teenager Aidan Dwyer has become famous in the solar energy industry and won a Young Naturalist Award from the American Museum of Natural History for his “sun tree” project. Being aware that leaves use sunlight for photosynthesis, Aidan noticed that they grow in the same sequence as the Fibonacci Numbers and used the same principle to build a “tree” out of solar panels. It transpired that this tree collects up to 50% more energy than simple flat panels. “Grown-up” scientists have now begun to study this phenomenon.
