I was pretty surprised and happy to learn that I won first prize (!!) in the Instructionables Go Green contest. I entered my solar thermal panel for less than five bucks project, you can read The Sietch version here, and the Instructionables version here. There were a lot of really cool entries, you should check them out. I for one have got a head full of ideas to try for my next project. I won a year long subscription to popular science, a robot t-shirt, and a solar charger for cell phones and the like (which is pretty cool).
