13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence
To see why they branch this way he built a small solar array using the Fibonacci formula, stepping cells at specific intervals and heights. He then compared the energy output with identical cells set in a row. Aidan reports the results: “The Fibonacci tree design performed better than the flat-panel model. The tree design made 20% more electricity and collected 2 1/2 more hours of sunlight during the day. But the most interesting results were in December, when the Sun was at its lowest point in the sky. The tree design made 50% more electricity, and the collection time of sunlight was up to 50% longer!”
His results did turn out to be incorrect though. Voltage (what he measured) is not an accurate measure of energy from a solar cell– he measured higher voltage simply because he swept a larger portion of sky. Solar cells in series are as only as good as the weakest one, so the tree design is only as good as the worst positioned cell for amperage, which multiplied by voltage creates usable energy.
This story is very inspiring and I think that Aiden’s passion to unravel a mystery shows how exciting the path of scientific discovery is. Impressively he is demonstrating the power of biomimicry — a concept that many see as the pinnacle of good design, but one that thus far has been exceptionally difficult to achieve. Way to go!
