Public Transportation is a great way to reduce pollution and traffic by reducing the number of cars on the road. Hybrid buses reduce emissions even further. While it is possible to find electric powered public transportation, most systems require cables, or tracks of some kind which require infrastructure, maintenance, and higher up-front costs. Engineers in Geneva, Switzerland think they have solved those issues with a new pilot program called Trolleybus Optimisation Système Alimentation, or TOSA.
