There newest version of the reelight runs off of eddy currents and the headlight puts out a steady 60 lumen beam and flashes for up to two minutes at a stop. The generator is placed close but not touching at the side of the rim.
And the definition of an "eddy current?"
a localized electric current induced in a conductor by a varying magnetic field
Again, thank Mr Faraday. The magnet on the wheel, sweeping by a coil of wire IS the generator.
There is probably a large capacitor and regulator that allows the light to stay on after the wheel stops spinning. The light is likely low current LED; the flashing reduces the duty cycle, as well as attracts attention.
No magic... basic physics and engineering. Used to be high school stuff... where you would build a little motor... which works on the same principles.
Meanwhile, back in Copenhagen... the hate cars quip was a joke... hence the winky face.
