13 year old copies Nature to Improve Solar Performance


fibonacci solar tree


     Thirteen year old Aidan Dwyer was walking in the woods in Upstate New York in the winter and noticed a spiral pattern to tree branches. Aidan realized the tree branches and leaves had a mathematical spiral pattern that could be shown as a fraction. After some research he also realized the mathematical fractions were the same numbers as the Fibonacci sequence. "On the oak tree, the Fibonacci fraction is 2/5, which means that the spiral takes five branches to spiral two times around the trunk to complete one pattern. Other trees with the Fibonacci leaf arrangement are the elm tree (1/2); the beech (1/3); the willow (3/8) and the almond tree (5/13)."*

Aidan's backyard in Northport, NY.


     The 7th grader next wondered why nature used such a pattern? He concluded trees do so to collect maximum sunlight. So, he constructed two side by side solar arrays - one a typical flat-panel array that was mounted at 45 degrees, and the second, a solar array based on the Fibonacci pattern of an oak tree. He put both outside facing south. To his amazement, during the month of December, the tree design made 50% more electricity, and the collection time of sunlight was up to 50% longer than the flat panel array!

     Aidan discovered that the Fibonacci pattern helps deciduous trees, in higher latitudes, efficiently track the Sun and collect the most sunlight even in the thickest forest, on the cloudiest days. If an object blocks the light to a flat panel array, the array stops producing energy. But, the Fibonacci pattern allows some solar 'leaves' to collect sunlight, while some 'leaves' are in shade. Plus, the Fibonacci pattern helps the branches and leaves on a tree to avoid shading each other. Snow and debris slide off as well. Aidan is currently building tree arrays based on the other Fibonacci patterns of the elm, beech, willow and almond trees. He questions; is one pattern more efficient than another?

The American Museum of Natural History has awarded Aidan a Young Naturalist Award for 2011.


See the detailed description of his discoveries on the Museum's website: *www.amnh.org


Postscript: A science blog "The Capacity Factor" (which has since been taken off the web) has raised questions as to the methods used in Aidan's test. Although the American Museum of Natural History stands by its award, scientists have questioned why Aidan did not measure power outputs from the solar cells, instead he only measured voltage, without a load attached ("open circuit"). Also in question is his use of sub-optimal angles on the tree. See: www.theatlanticwire.com

And this alone is proof that there HAS to be a higher existence that made all of this.. it's simply FAR too complex to have happened by Chance or some random explosion.

THE KID IS 13 PEOPLE!! I hope he digs more into this and gets rich off the patent! Regardless of the amps vs. voltage arguement, unique experiments need to be retested to prove the results. When was the last time anyone did someone new, perfectly, the first time? I'm sure lessons were learned and future tests will satisfy the critics!

I like how people like to say, oh he is 13 he could have never done any of this stuff. Why? Because YOU couldn't do stuff like that? When I was 13 I was taking apart electronics seeing how they worked and putting them back together. It's called being more educated, simply because you didn't have such a good education doesn't mean everyone else didn't.

To all of the people saying his results don't show more power, you are incorrect. volts are the amount of power there are while current is the ease and speed of the energy, hence why it is called CURRENT. It is also why we rate batteries on their VOLTAGE not their amperage. Yes it is the amperage that will kill someone at a much lower number, but this is because of its speed the body can't keep up. Voltage can kill you but it will need a very high voltage to do so, this is also why we have high voltage warnings. Remember Amperage is the result voltage divided by the resistance (Ohms law).

To Dan about Reply 54: yes current is that which kills but voltage is the energy (energy per unit charge).
In a further test, it would be useful to plot both voltage and current (the product of which is power).
To Cool-Proxy.net: nice armchair quarterbacking. The logic you seemed to miss is the construction based on the Fibonacci series - the pattern found in tree leaves. So the idea was to see if nature's design was efficient and if that efficiency might me replicated in the design.

Nice to hear that young generation is thinking and experimenting. Of course the boy did the experiment wrong (at least the results are wrong and there is no logic behind them), but it's nice that he's trying. It takes only a lot of trying to figure out something ingenious.

Just to reiterate what I said below, it only takes 50 - 100mA to kill you, that's regardless of voltage. Voltage doesn't kill current (aka Amps) do. Voltage can make it easier for a current to pass through you but in the end, the current is the true power behind electricity. While there is no proof shown on this page that the tree design produced twice as much power, the voltage graph does not disprove it either.

You should read the page again. The fact that the solar panels produced 5.25v as opposed to 4.4v or 4.1v is not the evidence that it produced twice as much power. Volts don't equal the amount of power, amps do. To make it simple, imagine electricity is water. Volts equal the water pressure and amps equal the flow rate of the water. Here is a website that explains it more. http://science.howstuffworks.com/environmental/energy/question501.htm Anyway, don't be so quick to judge things that you don't fully understand.

The article says that the oak tree design yielded 50% more electricity, yet the kid's own graph shows that it was only more efficient by 1.24 volts. This is only a 30% percent increase in power. Furthermore, this clever seventh grader has skewed the graph shown to make it appear as if the oak tree solar panel yields way more electricity than the standard model. If the voltage increments on the y axis started at 0 volts instead of 4, the difference in size between the two bars in the graph would not nearly be as huge.

The tree has more cells than the flat sheet from what I can see. That would account for the voltage difference. It is correct that in the end power is all that really matter and would need to be measured. The use of scientific method is excited. Now he just needs someone with a grant to build on his work. Thinking about it the theory isn't that valid. The trees compete with each other where solar panels wouldn't. It would be interesting to how an array of these things interact.

Why not create an artificial gene or set of genes that turn trees into better conductors and causes trees to naturally produce similar chemicals to those found in solar panels, and then create a virus that targets all of the existing plants in the world. If at 13 you're already nerdy enough to do all of this, then by the time you finish college with multiple degrees in botany, organic chem, and chemical engineering, then it will be easy to do all that. Shoot for the stars enough times, and you'll eventually learn enough to make it there.

The negative feedback probably has less to do with the project itself, but rather the hyped "amazing-breakthrough" that is being attributed to it by bloggers NOT THE KID.

This is not a revolutionary design, but it IS an interesting bridge between nature and technology.

To the kid - Good job - keep up on the discoveries.

To the bloggers - don't get so over-hyped about this stuff - green tech does NOT always = better tech.

What this kid has done is amazing. He's got a fresh perspective on the world that is going to bring him to the top of whatever field he decides upon studying. Mocking his methods, graphs, etc. is laughable. He's still a kid; he's supposed to make mistakes. It doesn't make his achievement any less impressive.

The wonderful part is that some of you trolls will probably be working for this kid someday.

Wow, can we remember this is a 13 year old kid? There is a lot of harsh feedback in here. I'm not saying we should take his research as fact at this point, more studies should be done in more controlled environments, but I feel that anyone who is finding fault in his spelling or his layout of his graph is just sad that they haven't accomplished as much in their adult life as this person has in a mere 13 years on this planet. We should applaud him for getting out there and trying something new instead of criticizing him.

In keeping with being inspired by nature, maybe the different designs have different efficiencies on different parts of the globe, and that's why different trees have different sequences.

That and probably the personal preferences of their DNA

Congratulations to Aidan.

For a thirteen year-old to recognise how a quirk of nature can be applied to a modern day problem, devise a scientific testing method and produce coherent and significant results is fantastic.

As Drew mentions the graph is a snapshot of voltage at a particular time not an indication of power produced over time.

I'm certain that as Aidan progresses he will refine his methods, improve efficiency further and go on to bigger and better things. The trolls on this forum however will continue to languish in their homes attempting (and failing) to pick apart the work of greater, more intelligent people whilst contributing nothing to society.

Before making any negative comments you should at least read the full story: http://www.amnh.org/nationalcenter/youngnaturalistawards/2011/aidan.html

uhh the efficiency is actually improved by roughly 16% not 50% also im not sure this is even statistically significant.

I admire this boys observant skills and he doubtlessly has a great future a head of him.

however this article fails to prevent an unbiased view of the findings. Personally I think we need to weigh the benefits of 16% increased efficiency vs the increased production costs and increase in space used. Making many small solar pannels in an array like it is described is many probably more expensive than the small gain in efficiency
