The Steam Engine By What are they? Steam engines are the first kind of engines to see a widespread use. They were used in the early locomotives, steam boats and factories. In fact they are still used to help run nuclear powerplants. When and by who were they invented and improved? The very first steam engine was built by Thomas Savery in 1698. However, it didn't turn any wheels, instead it pumped water out of coal mines. In 1712 Thomas Newcomen introduced an improved version of Savery's engine. James Watt improved it even further and later came up with an idea on how to use a steam engine to power something with wheels. Alright, but why are they important?
