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. GE has discovered that you can capture and store that energy, then reuse it.  This is how their hybrid diesel-electric trains will work, resulting in dramatically reduced nitrogen oxide emissions…but in super slo-mo video form, it’s as visually stunning as it is environmentally friendly.

Taken from the latest episode of The GE Show and created in partnership with The Barbarian Group, watch the video to see a simple illustration of the physics behind dynamic braking:
