O yeah great; let's load all the trees everywhere with solar panels! Should look fun next to the fields filled with wind turbines! Or let's alternate fields with the turbines with fields filled with artificial solar panel trees!
Looking at all the "WoW Nature is Amazing" posts make me think how many of you actually learned about photosynthesis efficiency. Only 3% of light that reaches the chloroplast is absorbed. That amount isn't bad, and it's higher than most synthetic processes, but it is no were near "WOW."
Yes this is a good idea.I have been trying different methods myself.I have gotten the best results by using reflectors instead of more panels.This cuts down on cost and maintenance.A panel centered with sun tracking reflectors beaming much light to the panel.The heat produced is an energy source in itself exceeding 500 degrees.
The whole thing looks like a confused science project to me. He never measured power output, all he measured is open circuit voltage.

I hate to burst everyone's bubble, but that kid's design is flawed. The reason the "tree" did better was because it has twice as many PV solar cells. Just look at this picture: aidan_large_08.jpg
The flat panel has 10 PV cells, and the Tree has 20.
The kid should get the Al Gore award for fake Science.edit on 8/19/2011 by Cryptonomicon because: (no reason given)

Given that the amount of energy that can be generated from a solar cell is directly related to its angle with respect to the sun, if that relationship is linear, then there would be no additional efficiency gained by using the solar array "tree" over a static solar array panel. In fact it would probably be less efficient. However, that relationship is nonlinear and the amount of power generated by the solar cell falls off quickly with an increasing incident angle. This webpage provides a formula that indicates that the solar array power varies as a constant raised to the power of the secant of the sun's incident angle with respect to the solar array. So, at certain times of the day, a few properly oriented "tree" solar cells could potentially provide more power than an entire array of fixed solar cells.

OK, I'll bite. What does political ideology have to do with solar arrays and the sometimes brilliant thinking of children?
But I do agree that it is how we raise our children, to be more observant, and to use their minds that are the key to the future.
Not all will be scientists and engineers, but we will always need plumbers, electricians and farmers.
