The media has been all over the fact that opportunistic New Yorkers have been using docked Citi Bikes as their own personal exercise machines, but what if all of that pedal power could actually be put to good use? The technology to harness kinetic energy produced by biking already exists, and if implemented on Citi Bike stations, could generate power for charging cell phones, emergency equipment during blackouts or even the Citi Bike system (which has been experiencing power-related issues lately) itself. So would it be feasible to turn Citi Bikes into human-powered generators and how much would it cost?
