View Full Version : Teen Uses Fibonacci Sequence to Make Solar Energy Breakthrough

A teenager is about to change the way we collect sunlight.

Long Island resident Aidan Dwyer is just 13 years old and is already a patented inventor of solar panel arrangements.

On a winter hiking trip, the teen noticed a pattern in the tangled mess of branches above him. Aidan took photos of the branches that "seemed to have a spiral pattern that reached up to the sky." His curiosity quickly led him to investigate "whether there is a secret formula in tree design and whether the purpose of the spiral pattern is to collect sunlight better."

Aidan applied the Fibonacci sequence, a mathematical principal found in nature, to a "tree-like stand affixed with small solar panels in the Fibonacci pattern," TreeHugger reports.

When Aidan compared his model's ability to collect sunlight with traditional flat-panels, the one based on tree-growth patterns won, producing 20 per cent more energy than the flat panel arrays. During winter, when sunlight is at its lowest, the tree design outperformed the flat panels by 50 per cent.

"The tree design takes up less room than flat-panel arrays and works in spots that don't have a full southern view. It collects more sunlight in winter. Shade and bad weather like snow don't hurt it because the panels are not flat. It even looks nicer because it looks like a tree. A design like this may work better in urban areas where space and direct sunlight can be hard to find," Aidan wrote on the website for the American Museum of Natural History, which named him one of its Young Naturalist Award winners for 2011.

His model garnered plenty of interest, with various "entities" seeing the commercial potential of the new technology. The United States Patent and Trademark Office awarded Aidan with a provisional patent for his innovation.

"I'm interested in science because it helps the world," Aiden told Northport's Patch community.

Great news, great observational skills this kid will go far, especially now that they have developed individual inverters for single panels at an affordable cost. What most people are not aware of is that an inverter is designed to convert DC to AC at the LOWEST potential coming off the series of panels, this means that if one panel is shaded and producing 20% less than the other panels the inverter will only convert at the potential rate of the shaded panel. Thus not converting the true potential of the array.. by giving each panel its own inverter this problem is eliminated....

I really like the image of solar panel trees... what a great idea...

Wiring parallel takes care of that problem too but the individual inverters are a better choice by far. Now, if we can just come up with the same chemical on the tip of a blade of grass that makes the blade follow the sun's path... ;=} Still more fond of the concentrators, even for residential use. What do you think of the flywheel vacuum design for energy storage? Its already out there in use. It feels more like a generator to me, it has a motor, so it needs initial energy input but it also works like a UPS.

Smart kid, on his toes. Good stuff.
