JR East's new experiment consists of energy-generators under ticket wickets, a milliwatt-tracking counter, and 700,000 daily commuters. For the next two months, the railway company will be using using the vibrations of human footsteps at Tokyo Station to generate up to 100 milliwatts per second per person that walks through. The idea is to be able to generate enough electricity to power the wickets themselves and their display panels regularly.Link
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.
