Title: 13-Year-Old Makes Solar Power Breakthrough by Harnessing the Fibonacci Sequence

While most 13-year-olds spend their free time playing video games or cruising Facebook, one 7th grader was trekking through the woods uncovering a mystery of science. After studying how trees branch in a very specific way, Aidan Dwyer created a solar cell tree that produces 20-50% more power than a uniform array of photovoltaic panels. His impressive results show that using a specific formula for distributing solar cells can drastically improve energy generation. The study earned Aidan a provisional U.S patent – it's a rare find in the field of technology and a fantastic example of how biomimicry can drastically improve design.

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 work is certainly piquing the interest of the solar industry, and even more 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!

Hm, u ovoj vesti nije uzeto u obzir da ova konfiguracija drveta zauzima više mesta od niza panela. U svakom slučaju, svaka čast dečku.

Quote from: AidanThe tree design takes up less room than flat-panel arrays and works in spots that don't have a full southern view.


Pa ti vidi.

Pa evo gledam sliku. Meni se čini da ovo plavo "drvo" zauzima više mesta od žutog krova.

Blargh.
Uvijek su me nervirali ti balavci što su mnogo pametniji od mene.

Od tebe nije teško biti pametniji. :)
