I saw this online and thought this might interest some people here.

The Copenhagen Wheel is a back wheel that can replace a bike's old back wheel. It is meant to assist bike riders when needed during their rides so that bikers can get farther faster. Energy is collected when going downhill and braking. Also, it has wifi capabilities to interact with one's smartphone.
