There are many green, automotive concepts - like variable transmission, cylinder deactivation and plugging into the power grid - that you might have heard about but have never seen. Want to see those concepts in action and not in a computer animation? Above is a video showing how a variable transmission system works. Think of the simple mechanics you can find on a ten-speed bike. Below the fold are two more videos including one of how power grid lines, so important they cannot be taken down, must be repaired by helicopter. Also below the fold is video of what actually happens in a cylinder, that tube with the piston and spark plug. Enjoy!
