Answer 2

Thomas Savery (/ˈseɪvəri/; c. 1650 – 1715) was an English inventor and engineer, born at Shilstone, a manor house near Modbury, Devon, England. He invented the first commercially used steam powered device, a steam pump[1] which is often referred to as an "engine", although it is not technically an "engine". Savery's steam pump was a revolutionary method of pumping water, which solved the problem of mine drainage and made widespread public water supply practicable.
