Answer 2

Answer:

In 1698 Thomas Savery patented a pump with hand-operated valves to raise water from mines by suction produced by condensing steam. In about 1712 another Englishman, Thomas Newcomen, developed a more efficient steam engine with a piston separating the condensing steam from the water.
