Excerpt from The Inner Light in the History and Present Problems of the Society of Friends
A marked feature of modern history is the tendency toward per sonal independence, self-sufficiency and autonomy. This is true in mechanics, politics, science and religion. The locomotive steam engine, the Diesel electric engine and the automobile all illustrate it. At first the benefits of steam power were confined to machines that could be reached from the engine by shafts and belts: the wonder of the locomotive steam engine and the automobile was that each carries its own generator within it. Electric power was at first confined to motors that were near enough to the power stations for current to be carried without too great loss through transmission lines whether trolley-wire, third rail or high tension wires. The Diesel electric locomotive of the streamliner carries its own generator.
