Watt experienced enhanced the steam motor of Thomas Newcomen, hitherto used to pump h2o outside of mines, and produced a reciprocating engine in 1769 able to powering a wheel. This was a big stationary motor, powering cotton mills and a variety of machinery; the condition of boiler know-how necessitated the usage of small-stress steam performing upon a vacuum in the cylinder, which required a different condenser and an air pump.
