Magnic Light: "contactless bicycle dynamo light" +VIDEO

Ingenious.

Looks like it needs a bit of smoothing in there, and some way of staying on for short stops at traffic lights. Depends upon the power generation and consumption, but a supercapacitor might do it.

The technology could almost certainly be used to power a light in another location, using cables just like a hub dynamo.

Wouldn't the electro magnetic induction occur in the rim, like a homopolar generator? How is the current passed from the rim to the light? or am i getting it all wrong, which is a possibility since the explanation in the vid seemed to be some guy scrolling up and down on a Wikipedia page about eddy currents.

Interesting. Reelights are pretty hopeless power-wise with a load of enormous magnets on the wheels, so what it's doing to produce enough electrickery without I am not scientific enough to begin to comprehend.

neat idea if it works but its got a few drawbacks. It would be obscured by the tyre from the other side so I guess you'd need one on each side for max visibility, even then it's quite low down so you'd probably want a higher mounted light as well. good lukc to the inventor though.

Decathlon do a rear light which works on the pulse caused by a spoke mounted magnet passing the light.

"we do not imagine will be too much of a problem for the Zipp, Ultimate and Reynolds wheels users on the racing scene."

Can only imagine racing with it in a 24 hour TT... Can't imagin too many other races where you'd need lights! At least, not ones where you'd also be riding carbon rims.
