Magnic Light iC is a revolutionary new micro-controlled, contactless dynamo-powered bike light system that works without any additional components attached to the wheels.
Designed by Dirk Strothmann, Magnic Light iC is powered by magnets and weighs around 60 grams. It can generate never-ending bright light without the use of any batteries, wheel-contact, cables or resistance!
What is most satisfying is how Strothmann brought together these principles of natural physics into the most efficient, usable product. This should certainly serve as another example to some bigger companies. Magnic Light iC is currently on Kickstarter and looking for funding.
How does it work?
The principle behind the Magnic Light iC lies in a very simple concept called Eddy Current (http://en.wikipedia.org/wiki/Eddy_current): Energy is drawn from the rotating bicycle wheels without any physical contact thus, without friction. Now, Eddy currents created by strong magnets generate electricity to power the lights.
When the wheel spins, magnets inside the generator induce eddy currents with corresponding magnetic fields in the wheel, which in turn interact with the magnets in the generator. The resulting electricity will power your lights indefinitely without any environmentally harmful batteries or cumbersome cables. You will not feel any resistance as the lights send their bright beam ahead. (International Patent Pending PCT/EP/2012/001431).
