A closer look

Waiting hours for an electric bus to charge is an operational nightmare. Geneva's TOSA transit system utilizes dramatic 'flash-charging' pantographs at standard bus stops. As passengers step on, a robotic arm instantly drops from a canopy, locking onto the bus roof to deliver a blistering 600-kilowatt jolt in under 20 seconds. It's a rapid-fire energy heist that keeps the timetable intact without needing multi-ton batteries on board.
