These domes have served as an effective shelter against wind, extreme heat and, once painted, rainfall. The largest of the three domes in the picture opposite measures approximately 12' 7" in diameter and is about 6' 3" high at its center. We recommend building the largest one. All the measurements throughout this web site relate to the largest size.Link (via Digg)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
