This kid is amazing. He uses the Fibonacci sequence, a naturally occurring infinite series of numbers, to rearrange solar panels to mimic tree branches. (The Fibonacci sequence is found everywhere in nature, from trees to the structure of dragonfly wings to the placement of seeds in a sunflower's head.) It collects 20% more solar power than a typical array and has an average of 2.5 hours more exposure because of the way the panels are arranged. Go kid!

What is strange is that this design is even more efficient in winter, but i guess this is luck cause i don't see why trees need sunlight in winter (except evergreen ones) ?

not to be a debbie downer, but the thing about the efficiency bonus is the bogus result of a 13yr old's understanding of electricity without a knowledgeable mentor, and sensationalist press.
please dont set up your solar panels this way.

Quasi, I saw the same debunking article you did after I posted this... though the fact is, they haven't actually shown that this DOESN'T work... they've just shown that the kid didn't properly show that it does work. Not quite the same thing. But you're right to bring it up, and everyone should know that there is some controversy around this at the moment.
The other reason I was excited about posting this was to teach permies about the Fibonacci sequence, however. The way these numbers appear in nature is amazing.

I saw this article too, and it gave me a really valuable clue as to why the wild grape vines don't like the support we offered them. These vines have been trying to come into the yard for years, and as the grapes make fantastic jelly, oh baby it's good, we wanted to encourage them. Hubby rigged up a ladder shaped thing out of leftover deck wood, and for a while the vines took, then they did a u-turn back to the forest they came from. They're designed, to seems, to go straight up, or horizontally, they didn't like the angle of their trellis. I'm not inclined to argue. This is pertinent to the pruning of fruit trees, too, no doubt.
And it would make for much more aesthetically pleasing solar arrays IMO. The ones I've seen in our neck of the woods are rows and rows of panels, set in gravel in once fertile farmland - a new kind of monoculture on the landscape.

The really refreshing thing about a young mind is that it sees only possibilities until we teach it otherwise.
He may be right, he may be wrong - but he's thinking about possibilities.
