Can nanotechnology be environmentally friendly? Joel Makower (cautiously) thinks so, and since his post is well-reasoned and full of good links, I’ll forgive him this: "When it comes to the environment, nanotechnology is no small matter." Ouch!
Also on the nano tip, check out Treehugger’s interview with George Whitesides, a Harvard professor who’s done lots of nanotech research of late.
