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.”

    So what exactly is new about ‘Dynamic Braking’. I was working with Kaiser Bauxite, Port Rhodes, Jamaica, over 40 years ago, when the Train Engines were using ‘Dynamic Braking’, with their ‘Diesel/Electric’ Locomotives.

    This was the main function of the these Engines, as from the ‘Mines (Bauxite) to the Port’, was entirely on a Downgrade, with up to 28 Cars, each carrying 80 Tons of Bauxite. With the weight of the Car, added, we talking some serious ‘Braking Power’ required here. And This over 40 Years Ago!!!

    If I knew what that video was all about, I might choose to make an informed comment, but I didn’t. Alas!

  3. buntyp makes a sound point..

    GE has been sitting on the Technical ability to do this for, nearly, 60 years..
