The "Red Alert" by Leader Sports operated by a nearly identical mechanism...and a lot cheaper. This is by no means the first magnet on the spoke design either.

Friction is near zero. You really don't feel it when riding. Having them fixed is a positive thing here, as it would take someone a whole lot of time and energy to steal them. Another really great thing about them being fixed is also that you ALWAYS have them on your bike. No more forgetting them and no more forgetting batteries. It's a cool commercialization. Cheers!

They had them at least as far back as 1952, if not earlier. http://www.sheldonbrown.com/dynohubs.html The only innovation is that this appears to be able to be mounted as an add-on to an existing hub - whereas the originals were part of a stand alone-hub. The other trade off, is that the light is fixed to the axle... which sucks Yeah, this is in no way the first.

A magnet moving near a conductor induces a current and experiences a retarding force, this converts kinetic energy into electrical energy. In a dynamo, the coils (conductor) spin inside a magnetic field, whilst here the magnets move near the coils. Doesn't anyone balk at reading claims of free energy?
