input: "I'm in Love with My Car" is amongst Roger Taylor's most famous songs in the Queen catalogue. The song was initially taken as a joke by May, who thought that Taylor was not serious when he heard a demo recording.  Taylor played the guitars in the original demo, but they were later re-recorded by May on his Red Special. The lead vocals were performed by Taylor on the studio version, and all released live versions. The revving sounds at the conclusion of the song were recorded by Taylor's then current car, an Alfa Romeo. The lyrics were inspired by one of the band's roadies, Johnathan Harris, whose Triumph TR4 was evidently the "love of his life". The song is dedicated to him, the album says: "Dedicated to Johnathan Harris, boy racer to the end".  When it came down to releasing the album's first single, Taylor was so fond of his song that he urged Mercury (author of the first single, "Bohemian Rhapsody") to allow it to be the B-side and reportedly locked himself in a cupboard until Mercury agreed. This decision would later become the cause of much internal friction in the band, in that while it was only the B-side, it generated an equal amount of publishing royalties for Taylor as the main single did for Mercury.  The song was often played live during the 1977-81 period. Taylor sang it from the drums while Mercury played piano and provided backing vocals. It was played in the Queen + Paul Rodgers Tour in 2005 and the Rock the Cosmos Tour in 2008. Taylor would again play the song for his concerts with The Cross and solo tours, where instead of drums he played rhythm guitar.

Question: James Watt  (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.

Watt retired in 1800, the same year that his fundamental patent and partnership with Boulton expired. The famous partnership was transferred to the men's sons, Matthew Robinson Boulton and James Watt Jr. . Longtime firm engineer William Murdoch was soon made a partner and the firm prospered.  Watt continued to invent other things before and during his semi-retirement. Within his home in Handsworth, Staffordshire, Watt made use of a garret room as a workshop, and it was here that he worked on many of his inventions. Among other things, he invented and constructed several machines for copying sculptures and medallions which worked very well, but which he never patented. One of the first sculptures he produced with the machine was a small head of his old professor friend Adam Smith. He maintained his interest in civil engineering and was a consultant on several significant projects. He proposed, for example, a method for constructing a flexible pipe to be used for pumping water under the Clyde at Glasgow.  He and his second wife travelled to France and Germany, and he purchased an estate in mid-Wales at Doldowlod House, one mile south of Llanwrthwl, which he much improved.  In 1816 he took a trip on the paddle-steamer Comet, a product of his inventions, to revisit his home town of Greenock.  He died on 25 August 1819 at his home "Heathfield" in Handsworth, Staffordshire (now part of Birmingham) at the age of 83. He was buried on 2 September in the graveyard of St Mary's Church, Handsworth. The church has since been extended and his grave is now inside the church.
