Explanation:

British inventor Richard Trevithick takes seven of his friends for a test ride on his “Puffing Devil,” or “Puffer,” the first steam-powered passenger vehicle, on December 24, 1801. Unlike the steam engine pioneered by the Scotsman James Watt, Trevithick ’s used “strong steam”–that is, steam at a very high pressure (145 pounds per square inch, or psi). Trevithick ’s engines were extremely versatile: They could be put to work in mines, on farms, in factories, on ships and in locomotives of all kinds.
