By introducing the separate condenser, approximately how much fuel did Watt's improved engine require compared to the Newcomen design for the same work?
Answer
Less than one-quarter
The economic impact of the separate condenser was profound, allowing Watt's engine to operate on less than 25% of the fuel needed by the Newcomen engine to perform the same amount of work.
