Bus maker Alexander Dennis to fit GKN Gyrodrive flywheel hybrid systems to 250 buses; partners on international development

Green Car Congress

Instead of a battery, the Gyrodrive system uses a magnetically loaded high-speed carbon-fiber flywheel to store the energy generated by a bus as it slows down to stop. Used in this way, the electro-mechanical efficiency of this technology is very high compared to competing electric storage technologies, the company notes.
