Toy Invention Activity Sheet. Trevithick’s engine, which generated greater power than Watt’s by operating at higher pressures, soon became common in industrial applications in Britain, displacing Watt’s less-efficient design. In 1765 Scottish inventor James Watt, building on earlier improvements, increased the efficiency of steam pumping engines by adding a separate condenser, and in 1781 he designed a machine to rotate a shaft rather than generate the up-and-down motion of a pump.
