Bill Gross, someone I find interesting and have followed for over 10 years now (check out the history of IdeaLab), gave a talk at TED concerning solar energy. See the video below.
I guess it should not be surprising that a really efficient solar energy collector would look like a flower.
Soar is where the planet gets its energy, and if harnessed better, we could use it for more of our energy usage. Below is a map from the presentation of where the “hot spots” are for solar within the US. The darker red spots get the most sunlight, the blue areas get the least.
