Which inventor is known for improving the steam engine by adding a condenser?

James Watt is recognized for significantly enhancing the steam engine by incorporating a separate condenser. This innovation greatly increased the efficiency of the steam engine, allowing it to use less fuel and producing more power. Before Watt’s improvements, earlier steam engines, such as those developed by Thomas Newcomen, operated inefficiently, as they utilized the same cylinder for both condensation and steam generation, resulting in considerable energy loss through heat. Watt's addition of a condenser, which allowed steam to be condensed in a different component, minimized this heat loss and led to higher performance. His advancements were pivotal not only for steam engines but also for the wider mechanization that fueled the Industrial Revolution, making industrial processes faster and cheaper. This innovation fundamentally changed industries such as textiles and mining, marking Watt as a key figure in this transformative period.
