Modern Marvels: Electronic motors make appliances run. They are the machines that drive the world, literally. From cars to can-openers, ENGINES are everywhere. MODERN MARVELS stokes the fires and sets off on a whirlwind tour of the world of power, throwing open hoods, peering into the cowlings of jets, and ignoring signs of "no user serviceable parts inside" to expose the secrets of a host of different motors. From the steam engines of the Industrial Revolution to the rockets that propelled man into space, ENGINES concentrates on the power plants that have had a profound effect on the way we live, but that doesn't mean it overlooks the little ones--in fact, the coming micro-technology motors promise to add a jolt of power to a whole new range of devices.
