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

Northport Middle Schooler Aidan Dwyer has accomplished more in his life than most people three times his age. He sails, he golfs-- and he is a patented innovator of solar panel arrangements.

Aidan has used the Fibonacci sequence to devise a more efficient way to collect solar energy, earning himself a provisional U.S. patent and interest from "entities" apparently eager to explore commercializing his innovation.

Summing up his research and imagining the possibilities, Aidan wrote: "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's essay titled The Secret of the Fibonacci Sequence in Trees is a winner of the 2011 Young Naturalist Awards run by the American Museum of Natural History who describe the awards as "a research-based science competition for students in grades 7-12 to promote participation and communication in science."

For large scale solar projects isn't this kind of thing achieved by just attaching motors to the thing and tracking the Sun? The calculations for that are pretty straightforward and since the panels are fairly light I can't imagine it's that hard to have some small motors keep the things pointed at the Sun all day.

It would be nice if this turns out to be a major contribution to solar engineering, and in fact it sounds clever. But I am wont to distrust this sort of story. "Boy genius" and "green breakthrough" are both stories too nice to fact-check.

You don't even need motors. I saw something similar that worked by using a sealed system of black iron pipe (painted black) and liquid propane (just like in the tank next to your BBQ grill). When the panel wasn't square on to the sun, some of the black iron pipe was exposed to the sun - the propane there boiled and condensed in the pipe in the shade. The shift in weight caused the system to tilt until the right sections of pipe were back in the shade and the panel was facing the sun again.

Indeed it is. In fact, passive solar tracking systems don't even need motors; they are themselves powered by the minute heat differential between the closer side and the farther side and move to correct the imbalance.

It's great that this young inventor has the resources, education, and adult mentors to enable and facilitate his experimentation. Johns Hopkins, for instance, hosts an annual "young engineer" summit for high-schoolers. The award-winner one year was a kid who made a cheap, functional SEM out of "spare parts lying around his parents' house." I wish more children had access to parents who can help them build an SEM and houses filled with spare electronic parts. As is, this sadly reminds me of cub scouts building wooden track racer cars out of specially designed parts their parents bought at hobby stores, using extensive help from their parents, in their parents' well-equipped garage workshops, while other children labor over a plain block of wood.

Here are some opportunities for engineering-inclined youth (courtesy of the Center for Talented Youth).

This is a good essay and good science from a child, but it is not a breakthrough.
I needed to compare the tree design pattern's performance. I made a second model that was based on how man-made solar panel arrays are designed. The second model was a flat-panel array that was mounted at 45 degrees.
He's comparing his tree design against a flat panel at a constant angle. That is, it doesn't track the sun throughout the day (in azimuth) or the season (in elevation).

A standard house installation of PV doesn't track either, but I don't think putting a tree on your roof will solve that.
posted by DU at 8:44 AM on August 19, 2011 [1 favorite]


And actually, there's a basic science (or at least engineering) error here:
It had the same type and number of PV solar panels as the tree design, and the same peak voltage. My idea was to track how much sunlight each model collected under the same conditions by watching how much voltage each model made.
Voltage doesn't measure an amount of power. Obviously you got the same voltage. Each cell proves a constant number of volts. But if you only point 1 of them at the sun, you get a lot less than if you pointed them ALL at the sun, which the standard design does.

He needs to measure watts, not volts.

Yay, kids engaging in the creative process of science and good scientific writing! But my god, breathless and under-critical reporting detract from this so much.

I am sure that using a Fibonacci spiral does help a plant avoid branch overlap because it's a developmentally accessible way to generate relatively prime numbers, but I fail to see how his experiment shows this at all. Look at the solar tree he constructed. Not only does he mount the solar panels at a number of different orientations, but the arbors are so small that he doesn't even need to worry about shade to begin with. He could have done the same thing with all branches being 120-180 degree angles and gotten identical results, I'm guessing, due to the factor of multiple orientations. Though well constructed overall, I'm fairly disappointed that none of the entries did work that didn't have a flaw so significant to its central point.

I love stuff like this. I've been a judge at my local science fairs for years because I love kids imaginations. Sure, 90% are just doing a class project, but there's always one or two doing it just because they want to, have to, KNOW, because it's neat.

Not all of them have great resources, certainly not to the level of this kid, or are as smart as he is, but I've seen kids come back year after year, graduating through beginner to intermediate to senoir categrories (primary, middle school and high school) with projects that build, year to year on what they did before. The amazing thing is not the science they're doing, but the inventiveness and creativity.

The process of modern science most closely resmbles double entry bookeeping, a complicated framework of statistics and QA/QC controls. It can be grinding and exacting, but we can teach that to most anyone who is capable of getting a degree. We can't teach the spark.

He's got the cells wired in series. I think what he's measuring is how many cells are on at a given time, rather than how much power is being produced (though he doesn't seem to realize that). Agreed that this is a completely useless measurement for the stated comparison.

Where I grew up the kids who won the science fairs just happened to have parents who were scientists in the very subject the kids project was on.

He's comparing his tree to a 45 degree roof configuration with half the panels facing south and half facing north. Measuring from October to December at a New York latitude, the north half of the roof panels receive zero direct sunlight throughout most of that period. So he's really measuring 20 panels of his tree against 10 traditionally angled rooftop panels + 10 negligible panels receiving no direct sunlight. In the real world, few people place panels on the side of the roof opposite the sun due to its inefficiency. A more realistic experiment would be to put all 20 panels on the south side. I would guess that his tree would be the worse performer in that experiment.

I saw patterns that showed that the tree design avoided the problem of shade from other objects. Electricity dropped in the flat-panel array when shade fell on it. But the tree design kept making electricity under the same conditions.

These are some unusual conditions for solar arrays. When ideally sited, they are not exposed to shading at all except from clouds. As stated above, the voltage alone is not an indicator of performance and it appears he's measuring the open-circuit voltage to boot. "The fact that the voltage varies little with changing sun light levels makes PV devices well suited for battery charging applications."
It's hard to say much about this without having current measurements. Additionally, when the cells are wired in series, the current of the entire series of cells is limited by the current output of the most-shaded cell. So in this circumstance, if any one cell is entirely shaded on the entire tree, the current output of all other cells is reduced. That being said, this could prove to be a potentially useful arrangement for certain conditions. Of course, we'd need to do some properly-designed experiments to determine that.

It's very attractive, but I unfortunately have to agree with the folks identifying the experimental flaws. At a purely physical level he appears to have used somewhere around 20 collectors on the "tree" to match peak output the same as 10 collectors on the flat panel array. Of course, this means that there is nearly twice the raw capacity for picking up light at other angles to convert into energy over time.

Likewise, that tree framework is a lot of embodied energy that needs to be accounted for in the life of the unit. A more even comparison would have used the same number of panels in both configuration and then measured daily (or annual) production from each (kWh).

Well, I, for one, will admit that I bring some personal baggage to an article like this, even though I think it's totally cool to apply Fibonacci and that it's a 13 year old doing it.

I'm jealous as fuck when I hear about how privileged youngsters do something cool. I'm irritated at the fact that, although I was a smart, precocious, science-minded child with an eager eye and a thirst for knowledge, I was born into a family of poor, conservative farmers in the Bible belt who thought education was suspect, who thought reading was sissy and who gave no encouragement at all to intellectual pursuits. I'm also irritated that we moved over a dozen times by the time I was 18, had five divorces in my immediate family and had to make it through a very, very rocky relationship with an alcoholic stepdad.

My youth was extremely disrupted by just trying to survive, yet I studied chemistry from age 5, was reading and annotating the family's ancient thrift-store encyclopedia at age 8 and going out into the woods to collect biological samples to study in a microscope I made myself at age 10. I eventually managed to put myself through college as a National Merit Scholar and working like a dog, being the first member of my family ever to even care about going to college, much less doing it. Yadda yadda self-pitying whining, etc.

So yeah, when I read an article about some precious kid and how he did something neat for his science fair, I read it with a mix of scientific eagerness, but also bring a lot of personal history to it. Not that it's the kid's fault. But it does make me cast a very jaundiced eye on an article that extols the boy's precociousness when I was doing similar things under, evidently, much less privileged circumstance. Sailing and golf, indeed.

All that residual rancor fades, though, in the face of an elegant application of the Fibonacci to an engineering problem. Even if it may be poorly reported and even if the child may have had some extraordinary assistance from privileged family and position, still: it's PHI we're talking about and that's pretty damn awesome anytime you get to consider it. My own unfortunate personal baggage, and the reporter's inadequacy, notwithstanding. :)

posted by JimmyJames at 12:03 PM on August 19, 2011


clockzero -- he's measuring voltage and claiming his results indicate "more electricity". Electricity is properly measured as power (often presented as Watts), not just voltage. This is bad experimental design. He isn't testing for what he thinks he is testing for.

It is exactly like measuring how fast the water in a river moves to determine how much water the river carries.

But you can't -- water speed isn't enough. You have to know how big the river is, too. To measure flow rate, you calculate flow speed times flow cross section.

To measure power, you calculate voltage (which he provides) times amperes (which he does not).

For a valid experiment, he simply could have attached a small electric motor with a propeller on it to his apparatus and got an approximation of how fast the blade was spinning to determine how much power was being generated.

As growing up middle class, and being privileged to have two smart, college-educated parents who are pretty great, overall, I can firmly attest that I had no patented inventions by the age of 13, and in fact had not even been profiled in a newpaper, magazine or blog.

In fact, my most exciting science fair entry was a papier mache volcano, made with patient help of the parental units. The Patent Office was not interested in my "Method for the Design, Production and Display of Simulated Volcano Demonstration for the Education of Youth."

Um, no. That's not how it works at all. A motor will spin faster as *more voltage* is applied but even then probably not in a linear manner.

To look at your analogy of a river, voltage is like *water pressure*. If you have a device that runs on water, and you hook it up to a pipe the more pressure the faster it will go. Current is like flow rate. And *resistance* is like how much back pressure the device you've hooked up stops the water from flowing through (And this is more like all the water in the river has to flow through your device, rather then a small part being diverted. So it's more applicable for a tube then an open river. Anyway.

Basically you use the equation V = IR, and then P = V * I. V = voltage, I = Current R = Resistance and P = Power.

You can simplify the power equation to V2/R.

So here's the thing. Power is completely defined by the voltage and the resistance. And Resistance is defined by whatever you connect to the power source, it's not an intrinsic property of the power source itself, although there will be an internal resistance, which is what prevents you from starting a car using 8 AAA batteries.

Anyway, measuring voltage seems like it's a pretty reasonable way to go about measuring how much sunlight a solar panel is receiving, as long as there is some load (I guess). If there was no load I guess it might not work that well (the panel might continue to increase in voltage until it stopped working)

---

Anyway, I'm really skeptical about the science as well, It seems like a flat array of solar panels will do better, provided they are positioned properly, and it's really hard to buy that this design is more efficient. If he included north facing panels then he was definitely doing it wrong.

So, how necessary is the Fibonacci sequence for this result? How does his design compare to, say, an array of cells randomly distributed on a spherical surface? Namedropping famous dead people for no real reason is for Dan Brown novels, not actual science.

Lighten up, people. No one is attacking you for not building solar cells instead of commenting on Metafilter. Can we please not do the whole, "Oh yeah well he has money and privilege so it doesn't count," routine?

Apparently not. I should remember never to rEeFi articles about anyone accomplishing anything; life is too short to wade through she shitpool of whiney, hate-filled jealousy. Pity it drowns out the people tying to speak to the value of the science being done.

This is every sociology talk I have ever listened to. I'm sure an eager anth student has tallied up the "shibboleth fraction" of the average conference talk.

I'm sorry to dash this kid's hopes, but as a person that works with solar power regularly (as a power source for off-grid telecommunications sites and BTS sites in developing nations), he has it all wrong. Here's why:

a) The mounting cost of large high powered solar modules is non negligible. If a 295W Canadian Solar module measuring 2.0 x 1.0 meters consisting of (72) 156mm cells costs $440, on average it will cost another $75 per module for a basic rooftop angle mount. The basic rooftop angle mounts consist of a few aluminum rails, feet to mount to the roof, clips that go on the rails to hole the module, and back-legs to give the aluminum rails some angle. More for a ground mount which requires concrete poles/foundation work. This adds up over the course of any size of solar installation.

a1) The wind loading of putting multiple 1.65 x 1.00 meter or 2.00 x 1.00 meter modules in the air on a tree like structure hanging in the wind is non negligible. Such a structure will be expensive to construct and will have an even more expensive foundation.

b) It's not news that a solar panel facing the sun directly will produce more power when the sun is hitting it at directly a 90 degree angle. In a mounting setup such as his tree where various solar modules are oriented vertically, whatever modules happen to be facing east when sunrise happens will produce optimal power, then as the sun moves through its course over the rest of the day the other modules which are oriented directly perpendicular to the sun will produce optimal power. In a theoretical setup where you have a perfectly cube shaped structure and can cover 3 or 4 sides of it and the roof in solar panels (as the German winning team from the 2009 Solar Decathlon did) you will produce more power than a single flat plate array of the same number of panels oriented in a single direction (typically pointing south at a tilt angle equivalent to your latitude).

c) If you have a string of solar panels with a number of units in the shade, the entire string's output is degraded. The "tree" type setup results in many of the panels on the tree being in the shade for part of the day. Micro-inverters aside, the only efficient way you can have a structure where a large part of the solar array is in shade for much of the day is by putting many separate strings on separate charge controllers (or inverters, in a gridtied setup) that are running in parallel.

c1) Imagine for a moment a small cube shaped structure with one side facing perfectly south. On the east side, mount two 300W modules vertically stuck to the wall. On the south side, mount two 300W modules vertically stuck to the wall. On the west side, mount two 300W modules stuck to the wall, for a total of six. This setup in combination with three separate charge controllers running in parallel will produce more power over the course of the day than the same six modules installed in a row at a latitude tilt. The east facing modules will efficiently capture the morning sunrise sunlight more efficiently than they would if they were oriented south and not facing the morning sunlight. The same principle applies for the sun's arc through the day for the south and the west facing modules. The problem that makes this setup more expensive is that it (again, without micro-inverters) requires three separate charge controllers or three separate gridtie inverters because part of the solar modules on the cube shaped structure are in shade throughout the day. If you connect all six solar modules in parallel to one large charge controller the kWh daily output will absolutely suck, because the shaded modules will be dragging down the power output from the 2, 3 or 4 modules that are in direct sunlight.

I'd like to add that as other posters have pointed out, his measurements are completely invalid because he's measuring volts, not watts or cumulative watt hours. Install the same number and specification of solar cells on a tree somewhere outdoor for a one month period and measure the cumulative watt hours generated. At the same time, during the same 30-day period, install the exact same number and specification of solar cells aligned in a row on a traditional angle mount facing south for one month and measure the cumulative watt hours generated.

The Fibonacci sequence isn't important really. It's unfortunate that he didn't measure power. It doesn't even matter that his experiment is particularly ground-breaking.

What's important, or would be important to the judges is why he did it and how he executed. My guess? He wondered was if trees could be "better" collectors than the flat panels he say on people's roofs. He did a bit of research, found the (well-known) Fibonacci structural relationship that tree and plants do, then tested his hypothesis: are trees better than flat panels?

That's pretty darn impressive for a 13-year old's project. It also seems obvious to me that he did not have a technically-able parent or advisor. The voltage measurement error is proof of that. Somebody with an EE or physics prof in the family would not have made that mistake. I'll bet he had a lot of parental and teacher help writing things up and in support for matrierals, but I'll also bet that he had almost no help figuring it out, designing the experiment or doing the work. It's quite typical of a bright mid-schooler's thought processes.

He doesn't have the structure and macheriery of "good" professional-grade science here. I'll bet there are no repeat trials, limited controls, no QA and certainly no significance testing. He got some basics wrong measuring voltage instead of power. Criticizing a 13-year old's science project for not being professional quality however is like expecting a 'tween runner to be doing under a 4 minute mile.

The important thing is that he had an idea and executed on it. It's not important that he's had a ground breaking idea, though the idea being his and not taken from one of the many science fair project websites or "study guides" is. I see many projects every year where, if only the kid had ten-years experience in the industry, they'd know that this wasn't the question the should be asking. However, he can learn how to do good science. He can learn what question should be ask. It's much harder to find kids who will ask questions in the first place. That's what things like this and science fairs are about, finding and supporting the kid who like to ask questions and who have some talent for answering them.

I'd also just like to point out that nobody ever wrote an article about me when I worked out the formula for the "secret hobo spices" in Moe's Hobo Chicken Chili when I was twelve.

(Meanwhile, having gotten over my self-pity, etc., I'm actually doing tres bien as a science educator nowadays, providing encouragement to folks with science aptitude, so it's all good. Kudos to the kid for even caring enough to try something innovative, even if he may have had help.)

My cynicism chip automatically activates when someone very young discovers something that adults working in that field for many years have not discovered.

I am sure that someone on MetaFilter can point out a case when this sort of thing really was what it purported to be; but I'm incredibly sceptical of every aspect of this story.

In other solar power news: Arizona Solar Tower 2X Taller Than the Empire State Building Will Produce 200 Megawatts

... will?

I think the phrase is 'might, in theory, if it were ever built, which it won't be' It's hard to buy that towers like that would be cheaper then Concentrated Solar Power.

As a poor kid who caddied for most of his youth I can say that I enjoyed golf more than the poor bastards trying to put the "motherfucking sonuvabitch ball in the god-dammed bloody hole". Plus I got 10 bucks and a hotdog and cola for lunch.

I also learned not to walk directly downwind of rich people. Apparently rich diets have consequences that probably also correspond to Fibonacci sequences.

Let's try this again. Solar-panel "trees" really are inferior (or: "In which hopelessly inept journalists reduce me to having to debunk a school science project")

I have no idea how accurate this debunking is but I'm a firm believer in open access to information & more than a little bit annoyed the post disappeared without explanation. So, have at it.

Absolutely! I don't think anyone on here thinks that these criticisms of the work reflect poorly on the kid. I hope he values the criticism and uses it to hone his own ability to think about how to test hypotheses. Trial and error in these things is about the only way one learns, and he clearly has a strong interest and knack for it.

However, the presentation of the work by the media as a "breakthrough" is ridiculous. There are seven other people who won the same award this year, at least one as young as this fellow. If the media wanted to highlight good youth science, they could easily have mentioned even one of them. Instead, whoever wrote the first article on this wanted to play it an example of the "young genius smarter than all those fancy-pants experts" narrative. As someone who has spent a lot of time and effort becoming a fancy-pants expert, to say this without even the slightest hint of due diligence in evaluating the claims is flat out insulting.

Interesting to read details of solar power (e.g. from thewalrus)

Actually though, reading his paper again, its not so much that he's trying to improve the way we use solar power, he's trying to explain why a tree's branches follow the fibonacci sequence and why that is an efficient arrangement for an arbitrary tree growing in an arbitrary space.

"My conclusions suggest that the Fibonacci pattern in trees makes an evolutionary difference."

The stuff at the end about a possible new way of arranging solar panels is like a corollary.

If this is the case then his conclusions are definitely unfounded. If he had all 20 flat-array panels facing the sun (instead of having 10 panels facing a wall!), his conclusion would have had to be that trees are doing it wrong.

Kudos to him for being interested in science. But he should also realize that his "experiment" was basically biased toward proving his hypothesis, rather than risking its rejection--that's a big pitfall in science and if he learns that lesson now he'll have a big advantage in the future.

Not really. Patents (like golf and sailing) can be had by anyone able to afford the price of admission.

Good for the kid for trying, but there are probably as-good/better ideas out there that will never get any attention because most folks are struggling just to keep their kid in food and clothing

And... the kid's science fair project has been well and truly debunked.

Before anyone gets all "poor kid doesn't deserve to be criticized for not being all college-level sciencey enough", let me point out that he did not measure what he purported (solar cell efficiency). This wasn't a great project that happened to have glitches; it was based upon a lack of understanding of the fundamentals he was working with.

13yo doesn't understand electricity; not news at 11.
