New system frees trolleys from cumbersome wires.

Zero emissions transportation solution.
TOSA electric bus
Electric transportation systems are one step closer to becoming integrated into urban populations.
Researchers at the Swiss Federal Institute of Technology (EPFL) have developed an electric bus that can recharge itself in just 15 seconds at a stop in what’s being called “flash” recharging. It’s a green infrastructure alternative that provides buses that are not only zero emissions, but are also able to roam free of cable tethers. These overhead wires can be a major inconvenience to the residents of buildings where the wires are attached. And TOSA buses are able to adapt their routes in the case of an accident or heavy traffic.
The researchers are still investigating this very question, trying to create a framework of necessary charging stations that would need to be installed in order to keep the network of buses running reliably and on-time. These recharging stations would be installed along the normal bus route, and would ideally be a cost-saving investment that reduces the amount of infrastructure needed versus the traditional method for powering trolleys. The other question researchers are factoring into their design is what happens when two bus routes converge, seeing as the charging station can only charge a single bus at a time.
