I saw a TV show recently that talked about steam engines and which visited Jay Leno's Garage, and talked to Jay about his many steam-powered engines and cars.
(For those who may not know, Jay Leno is an American comedian and long-time host of 'The Tonight Show', a late-night TV talk show. He's also an avid car enthusiast, and a has a huge collector of cars and engines of many types.)
Here's a link to a cool video about the oldest engine in his collection, a steam engine from 1832 out of a British factory.
