11 янв 1769 г. - Watt Steam Engine

Описание:

James Watt patented his revision of the steam engine in Scotland in 1769. Watt’s engine featured a separate condenser which filled the power cylinder with steam as the piston moved to the top so that it was immediately ready for another stroke instead of having to wait for the power cylinder to warm up again. This made the steam engine much faster and efficient, using only half as much coal to produce the same amount of power.
