I loved watching some story about a kid wondering if solar panels were arranged more like leaves on a tree they would gather more sun...a mix of nature and technology. I wonder how kids come up with this stuff. He said he came up with it on a hike. This isn't the original story I saw on this kid but you get the idea of his project.
