Energy & Dynamic Braking

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 above 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.

Ecomagination Challenge: Powering the Grid

GE’s Ecomagination Challenge: Powering the Grid is an open call to action for businesses, entrepreneurs, innovators and students seeking breakthrough ideas to create a cleaner, more efficient and economically viable grid, and accelerate the adoption of smart grid technologies and just might get funded.

The Challenge invites people to come together to take on one of the world’s toughest challenges - building the next-generation power grid to meet the needs of the 21st century.

Selected Ecomagination Challenge entrants will be offered the opportunity to develop a commercial relationship with GE through:
Investment ( $200 million capital pledge of GE and its partners will be invested globally into promising start-ups and ideas), Validation, Distribution, Development, Growth

Here is the visualization of ideas ranked by votes and comments. Check it out which idea going to get $200 million.
