The first working Western pump, the “Miner’s Friend,” was patented in England in 1698. It burned coal to boil water and then condensed the steam into a vacuum, whereupon operators opened a valve and the vacuum sucked water up from the mine. Now closing the valve, workers stoked the fires to boil this water, too, into steam; and then repeated the gravity-defying process of boiling and condensing over and over again.
