At Philadelphias 8th street station a smart grid dream concept is becoming reality. There, as trains approach the station and break, the kinetic energy will be transported to the power grid and used as local electricity. This is the first time a technology of this kind will be used in a major urban center and could pave the way for similar technologies such as capturing the kinetic energy of citizens as they walk in busy city centers like time square. So next time you’re waiting for the train and it begins to break, just think, it could very well be powering your home. Awesome job Philadelphia! Let’s hope it’s a success.
