the first type of steam engine to make use of steam at a pressure just above atmospheric. Watt's two most important improvements were the separate condenser and rotary motion.The separate condenser, located external to the cylinder, condensed steam without cooling the piston and cylinder walls as did the internal spray in Newcomen's engine, more than doubling Watt's engine's efficiency. Rotary motion was more suitable for industrial power than the oscillating beam of Newcomen's engine.
