Watt's Engine: From Pumping Mines to Turning Wheels
Captions available
The idea
James Watt improved Newcomen's pumping engine with a separate condenser, the witness dates it seventeen seventy-four, and with Boulton manufactured engines from seventy-five. The rotary mechanism turned heat into motion for wheels, not only pumps: coal replacing muscle and water.
In practice
Horsepower, the anchor notes, is Watt's word.
Where people slip
The anchor's seventeen sixty-three is when he began; the patent came later.
