|Tohoku during the 2011 tsunami.|
Following the devastation caused by the tsunami last year, a company called Senyo Kogyo (which designs rollercoasters and other amusement park rides) along with a team from Tokyo University's Institute of Industrial Science have designed the Eco-Ride, a train that will use largely its own inertia to move.
It will have no engine and be very light; gravity will do most of the work, so what little energy is required will cause next to environmentally unfriendly emissions. Its speed is controlled by 'vertical curves' in the tracks and should be able to travel at up to sixty kilometres per hour.
