So it's not edible, but it looks hot enough to be. :). London Garden, winner's of this years Future City Mobility have got it tight. I don't know how to ride a bike...but this concept makes me want to get into gear quick-fast.
A quick rundown, an area of London cleared off just for bikes. They're not ordinary bikes, they store energy, you ride them faster they store more energy - you don't pedal at all, they consume a little energy and become electric scooters. But more, the bikes are foldable, take them onto a public bus and they become your bus seat - and also (!) the energy you created whilst pedaling turns into credit for your bus fare.
And there are bike rack 'trees' that generate bike charging power from rainwater, sun and wind. Wa.
