Succeeded in developing a brake that makes use of wasted energy. 

When you go to school,if you see the traffic light is change from green to red,”I want to beat that light.”
I figured that I would see if it would be possible to set up a bicycle that really wants to stop.
If you really want to use brakes ,the number of traffic accidents will be decreased!!
So, this time I’m going to build a bicycle and give it the full Japanese technology treatment by using traditional fermented soy food ”Natto”.
