From the Ted Talk by Bill Gross: A solar energy system that tracks the sun

Unscramble the Blue Letters


A critical part that we can take advantage of is that we have these inexpensive microprocessors and each of these petals is autonomous, and each of these petals frueigs out where the sun is with no user setup. So you don't have to tell what latitude, lnougitde you're at, what your roof slope angle is, or what orientation. It doesn't really care. What it does is it searches to find the hottest spot, it secrehas again a half an hour later, a day later, a month later. It basically figures out where on erath you are by watching the direction the sun moves, so you don't have to actually eetnr anything about that.
