Nicola Tesla

the inventor of the engine dynamo, retained the furnace and the boiler, but constructed an apparatus which combined an engine and dynamo. This engine dynamo has hardly one of the features which distinguish an engine. There are no fly wheels, piston, crank shaft, belts, or the heavy iron frame visible. In fact, the machine has the appeare ance of a dynamo with a steam pipe directly connected to it. Tesla’s own explanation of this device is that the steam is used to create a vibrating motion of certain mechanism (in 2 cylinder) which separates so as to cut the lines of magnet force of the large field magnets in the apparatus, thus creating electricity. It is pointsd out that by this method imp or- ‘ant advantages are gained, viz., the absence of a costly engine; and what 's of much higher importance, the reneration of electricity at about one- 1alf the cost of former methods. These claims have been verified by the yperation of machines that have been nade and tested.
