Unique Design

I've never seen a group come up with an extended solar panel like this one. At first I was a bit concerned to think I had not gotten across that light travels in STRAIGHT lines! I knew they did not put a mirror in the tube to angle the light. Fortunately when I asked about their design they said it was to heat the air in the tube and send it into the box. I did not discuss the fact that heat rises... we'll review that another day!
