Pretty slick! The thing I dislike about the ones already on the market that go in the spokes is the weight and that its asymmetric weight. That set up is nice in the fact that it would be minimal weight added to the wheel and it is spread evenly on the circumference. Using the hub generator you could probably still drive a headlamp and be within the what the generator can handle.

Hope those kids patent that idea. They could very well have a million dollar idea if the can find the right buyer. Id be on the phone with Mavic, Alex and Sun the day I got the patten.

Looking at it they could easily run this on a battery without the hub generator to reduce the cost.
