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




In late 2012, early 2013, Aidan builds a larger model:






Postscript: Many have questioned why Aidan did not measure power output from the solar cells, instead he only measured voltage, without a load attached ("open circuit"). The American Museum of Natural History stands by its award.

I think it's amazing how one can think and gather information to use towards creating something that works based on the foresight to try something different, I give this teen credit and wonder what makes some of us so curious and knowledgable while others stand by and wonder about things in the world I congratulate him on making the effort succeeding and going forth with his ideas I wish him every success in life and hope to see more inventions from him!

A 7th Grader
Reply #98 on : Mon October 22, 2012, 21:07:19
your post script suggests that someone or group of someones decided that 13 yr old Aiden did not collect enough of the right kind of data in an experiment for the 7th grade. Maybe the 13 year old in 7th grade was not aware that adults would be critiquing his work so diligently and maybe the 7th grader all of 13 years of age-so no formal collegiate studies or professional acumen needing to protect their integrity-did not realize that he would be help accountable or criticism one could expect of a professional or a collegian. but me, i think kudos to the 13 year old 7th grader who noticed something so obvious and made it work for his experiment for the 7th grade.

More panels on the 'tree'
Reply #97 on : Thu September 13, 2012, 08:38:54
Many people have observed that there are a fair amount more panels on the 'tree' than on the house design and that this contributes to the higher production and not any real benefit to the design. However, as mentioned in the article this design causes many of the panels on the 'tree' to not actually be receiving sunlight at any given time whereas in regular lighting all 10 of the panels on the house will be receiving light and functioning at the same time. So while there are more total solar units on the tree design; there are likely to be relatively the same amount of solar units actually functioning at any given time.

Bravo to the kid for doing something that scientists do not do themselves. Actually experiments. Nicola Tesla criticized many in his era for the exact same thing, scientist instead would just work with mathematical equations on paper and in their head and believe this was how you find things out, they'd leave actual physical experiments out of it completely.

This is wonderful! So the great thing for Aidan is that since he is planning on testing other sequences, he can make improvements in his testing methods from the feedback. My understanding is the goal of scientific inquiry is to explore, test, refine, test and generally ADD to the body of knowledge.

Look at all these cynics. Political and religious agendas, cranky know-it-alls trying to tear down a young and curious mind. No wonder so few people go into science.

That's why people like Aidan are better than you. His experiments may not be perfect, but he is confronting the unknown with curiosity and more rigor than any 13-year-old I'm aware of. Unlike you, he doesn't assume he knows the answer. He tries to figure it out.

That's the spirit of discovery. I wish millions of other kids had it.

EVOLUTION
Reply #84 on : Tue July 24, 2012, 22:11:13
Wow! Evolution is an amazing thing! To think that trees just started as roots, but developed a need for a trunk, as so through selective pollination evolved to have trunks. But then they developed a need for branches, and so evolved to have branches. But then they needed leaves, and miniature solar panels on leaves that could convert sunlight to energy via photosynthesis! Little power plants...(no pun intended) that is truly amazi....wait, what? You mean to tell me that trees evolved? As if a root could survive without a trunk to support branches and hold leaves upward toward the sun to harvest sunlight. But without the leaves, and without the leaves' capability of complex photosynthesis, the whole tree would cease to exist.
This leads me to question whether my nostrils evolved first, my respiratory system or my lung's ability to breathe oxygen, which these trees just so happen to produce.
Maybe my mouth evolved first, and had to purpose for millions of years until my esophagus developed, which had no purpose until my stomach evolved and then my need for food, and millions of years later I needed a way to expel waste, so my digestive system..so on and so forth.
You mean people still actually believe in evolution? Stop seeing with your eye deviod of a conscience. Start seeing through your eye with your conscience! The micro/macro deception is real. But hey, as long as we can write life off as being meaningless, that means we don't have to hold ourselves to any moral standard, or we can make our own. Seek the truth and it shall set you free.

Remember it has been more than one hundred years since Albert Einstein developed the physics explaining how the photovoltaic cell works--the photoelectric effect. Thus began quantum theory. It will be at least three hundred more years before another person with the same intellect walks on this planet.

There are 10 cells on the house that you can see. I'm willing to bet there are 10 on the other side as well for a total of 20 cells on the house. it looks like there are about 20 on the tree. the other 10 cells would obviously not collect as much light, but i'm just sayin.

OK so I just posted here, but want to again after reading what others have posted.

And to legitimize my words I would like to say that I am a Mechanical Engineer Technologist.

The Purpose of Science is to Explore the Natural World from all angles. This kid has gone to much more intellectual depths than any 13 year old I have yet to encounter. his EXPERIMENT is indeed up to PROFESSIONAL SCRUTINY, and needs to be further studied. but the Fibonacci sequence has appeared in nature time and time again and most bio-mimetic engineers use it as a starting point. so don't knock the kid so much just because you have spent most of your life glued to the web. let his LEGITIMATE EXPERIMENT stand the TEST OF SCIENTIFIC SCRUTINY before you judge offhandedly.

When Fibonacci came up with the math that is expressed here, he called it the (and I paraphrase here because I don't remember the exact words) equation that describes God. Now, I am Pro Science, not Pro God, as anyone who is close to me can support. but this article supports why a SCIENTIST would believe in the concept of a God-based universe.

Great insight for a 13 year old. He displays an intellectual maturity much greater than most his age. However, there is nothing novel about this. This would be an extremely well-thought out science fair project, but he did not "realize" the Fibonacci sequence. The Fibonacci sequence is nothing more than a simple mathematical ratio that has been known for centuries. This very design has been built in much more complex and efficient structures that he could've read about by googling "solar powered tree." Definitely has the makings of a young, insightful scientist, but don't get excited because someone can use google for another other than porn at 13.

There also seems to be twice as many cells in his tree structure which is bound to produce more power (or voltage which is what he measured, depending on whether he connected the cells in series or parallel)

But at least the kid is thinking outside the box and I'm sure that he must be on to something. Plants must have evolved to be like that for a reason.

For everyone stating what power is, you are mostly wrong. Power=Voltage*Current fyi. And there is no possible way that a panel oriented in random directions on a fake tree structure would capture as many photons as a fixed single panel oriented at a tilt angle of that of the latitude of the location of the panel.

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!

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.
