Going green sometimes means taking a current concept somewhere that it's never been before--in this case into the air.
It began when Martin Angelov
sent a pencil sketch idea to the Line of Site competition in 2008. This international architectural competition looks for ‘quick’ initial ideas that capture the essence of creativity and mark the point when those ideas take shape.
The idea pictured here was to make flying bicycle-lanes, using steel wire, something like a ski lift, but working on the opposite principle in which the wire is static and it doesn’t need electricity.
The entire concept (and more not-for-the-Agoraphobic photos) is explained here.
Green is innovation, not unlike the students who designed wind turbines generating power over Interstate highways in this previous post.
