Mechanical inventors speak of a machine as efficient when it does its work without loss of power. If a hundred pounds of steam pressure are applied to it, the full hundred pounds are accounted for in valuable engine power. There _is no waste. Any instrument is efficient when it gets the most work from a given amount of effort.
