Thomas Savery built a model steam engine in 1698 called “Miner’s Friend” to drain mines.

Thomas Savery was an English inventor and engineer who patented the first practical steam engine, which he named the “Miner’s Friend”, in 1698. This engine used steam pressure and atmospheric pressure to pump water, primarily intended for draining mines.

Thomas Newcomen later developed a more effective atmospheric engine in 1712, which improved upon Savery’s design and became widely used for pumping water out of mines for several decades. James Watt significantly improved the steam engine in the latter half of the 18th century with his invention of the separate condenser, dramatically increasing efficiency. Richard Arkwright was a key figure in the textile industry revolution, known for his inventions like the water frame, and utilized steam power but did not invent the primary engines himself.
