I ran into a George Odhiambo, a bulk fabricator of everything from wheelbarrows to chisels. The chisels caught my eye, primarily because one of them looked a lot like a shaft straight out of a Land Rover. It turns out that they reuse multiple types of iron for their goods, including leftover pieces from old vehicles. Nothing goes to waste here.
Even more interesting to me (probably because it moved and did stuff with fire), was the bicycle-turned-to-bellows that kept the fire going that would heat the metal rods. It’s a fairly simple, yet ingenious contraption that utilizes old materials with a little bit of engineering. The thing runs all day, every day too, so it’s made to last.
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.
