Giving back....

As I excavate the depths of my bookshelves, I've started to go through piles and piles of articles I've torn out and meant to read. In that excavation I found this fantastic article about the trains in Oslo, Norway. These trains run on electricity that they get from the grid, pretty standard stuff. What is wicked cool is that all the energy it takes to go fast is reconverted back to electricity and sent back to the grid when they have to go slow. Using regenerative braking, what it taketh it returns. Sort of like a gigantic Prius.
