The second kind of buses was relayed by Engadget. This bus built in the U.K. converts the energy contained in human waste into mechanical energy, by means of 'anaerobic digestion' that produces methane. The bus can travel up to 180 miles/300 km. The bus is built by Scania and get its biomethane from a biowaste plant near Bristol. Engadget also has a video that explains how this bus works.
In conclusion, there are always sparks of innovation in the energy and transit industries. Let's see how soon we may get to enjoy them!
