Energy and Dynamic Breaking

GE has launched a neat site to help promote their locomotives (and other accomplishments), aptly named “The Rebirth of Rails.”  Typically, these things are fairly boring, when it comes to corporations flaunting their own achievements which have not benefited the general public. But that’s not the case with the few features from GE. They are quite fascinating and fun to watch!  Now, with that said, the fact that the rebirth of rails in America and in the eyes of GE has nothing to do with high speed locomotives is a bit disheartening.

“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*acceleration.” Not just interesting for nerds.

    It would be great of we could have some investment in the railways n the UK. They are tired old and unreliable here.

      You think they're bad in the UK? Come to America where the idea of anything high speed still goes slower than a car.
