The use of steam to pump water was patented by Thomas Savery in 1698, and in his words provided an "engine to raise water by fire". Savery's pump worked by heating water to vaporize it, filling a tank with steam, then creating a vacuum by isolating the tank from the steam source and condensing the steam. The vacuum was used to draw …
