Energy: you can’t destroy it, but you can certainly waste it. That’s what most motorized vehicles do, including trains. Usually, the energy generated when you stop a moving vehicle is dissipated as heat, and is lost to the atmosphere. With GE’s ecomagination we’ve discovered that you can capture and store that energy, then reuse it – that’s how our hybrid systems work. Watch the video to see a simple illustration of the physics behind dynamic braking. Keep in mind an object’s force is measured in newtons, using the equation force = Mass x Acceleration.
Question by Richard H: Do you think its time for Boeing and General Electric to start making dynamic passenger rail trains?
They would probably be very good at it.
Answer by James H Boeing was in the passenger train business, building the “US Standard Light Rail Vehicle”, which was a MISERABLE failure. They did build a successful series of subway cars for chicago, but were underbid on all other attempts.
Though GE, and for that matter Electro-Motive Diesele, are well known for their locomotives, getting into the passenger car market which is held in a tight grip by Bombardier and Kawasaki would be a nightmare.
