Two American Airlines mechanics didn't like having to toss out $200 drill bits once they got dull. So they rigged up some old machine parts - a vacuum-cleaner belt and a motor from a science project - and built "Thumping Ralph." It's essentially a drill-bit sharpener that allows them to get more use out of each bit. The savings, according to the company: as much as $300,000 a year.Link (via Kottke)
And it was a group of pilots who realized that they could taxi just as safely with one engine as with two. That was instituted as policy has helped cut American's fuel consumption even as prices have continued to rise to record levels.
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.
