Michael Mosley, Cassie Newland and Mark Miodownik from the 成人论坛 series 'The Genius of Invention' describe the scientific achievements of Nicklaus Otto, Karl Benz and Henry Ford. Prior to this, the steam locomotive had started a revolution.

Richard Trevithick鈥檚 design had a boiler but this was removed to make the internal combustion engine. The German inventor Nicklaus Otto developed the first four-stroke engine in 1876. This could not be developed until kerosene, diesel and petrol were used in place of coal.

Karl Benz then developed the world鈥檚 first car using Otto鈥檚 design. Within 15 years, cars were so popular that there were no more horses on London鈥檚 streets. Henry Ford then built the Model T in 1913, using the first assembly line, with stationary workers and the product moved to them. This method changed the way we manufacture goods.
