It's a big week for transit and sustainable cities in New York Time's T magazine. No less than five different travel and transportation innovations were mentioned in this travel issue. Teague's barebones stripped-down vision for high fuel efficiency flying - labelled Flight 2.0. A nod at Inspiro, BMW Group DesignworksUSA exciting new subway train design for Siemens. Joey Ruiter's Inner City unchained unicycle-based back-to-basics bicycle. Priestmangoode's double-decker bullet Mercury Train. And Thomas Heatherwick's modern icon for an old one - a replacement for London's classic, red open-platform, Routemaster double-decker buses. Woohoo.
