Forget Hyperloop, the Aerotrain-inspired SpaceTrain may eventually connect the French cities of Saran and Ruan. This futuristic train system operates in a system of subterranean tunnels operating in a low pressure atmosphere, enabling it to hit near-supersonic speeds, while preventing vibration and noise that would otherwise disrupt nearby neighborhoods.
The first prototype is said to be powered by a hydrogen turbine engine and manufactured using carbon fiber with graphene carbon breaks, graphene batteries, fuel cells as well as a host of other technologically advanced features. Simply put, it’s a stammeringly fast people mover with a eye watering top speed of 745 mph.
