SUMMARY:'Better than Steam? Davy\, Faraday\, the Brunels & the Gaz Engine\, 1823-1833' by Professor Frank James
DESCRIPTION:Image Credit: Crown copyright\, photograph by Frank James \nThis event is both an in-person and on-line event. No need to register – just come along or click this zoom link to join on-line. \nIn early March 1823\, laboratory assistant Michael Faraday\, at the Royal Institution\, unintentionally subjected chlorine to a very high pressure and\, much to his surprise\, found that it turned into a liquid – the first time that a gas had been liquefied.  \nAside from the scientific achievement\, very quickly this phenomenon came to be seen as having the potential to be a new source of power. Steam-power was not necessarily seen as inevitably replacing wind or water-power. This is illustrated by the large amount of effort devoted by savants\, including Faraday and Davy\, during the 1820s to exploit gas liquefaction practically in what was termed the ‘gaz engine’. Furthermore\, the engineers Marc Brunel and his son Isambard Brunel also devoted considerable effort to render gaz engines feasible. The Admiralty\, then beginning to use steam-powered vessels\, was also very interested in gaz engines and provided limited support for later stages of the research.  \nFollowing repeated failures to develop a practical engine\, at the start of the 1830s work ceased on the project. In modern terms\, what was being attempted of course was to obtain more energy from a gaz engine than was required to liquefy the gas in the first place\, that is a form of perpetual motion. Once the laws of thermodynamics had been formulated during the 1840s\, the pursuit of such a source of power was seen as clearly impossible. Before then it was not clear\, even to leading savants and engineers\, that what they were doing was seeking to build a perpetual motion machine.  \nThe story illustrates just how invisible perpetual motion could be.  \nAbout the Speaker\nProfessor Frank James\, a former President of the Newcomen Society\, is Professor of the History of Science at University College London. His main research centres on the physical sciences in the late eighteenth and early nineteenth centuries and how they relate to other areas of society and culture\, for example art\, literature\, business\, media\, religion\, engineering and the military.  \nFrank edited the Correspondence of Michael Faraday\, published in six volumes between 1991 and 2012\, served as an advisory editor for the four volume Collected Letters of Humphry Davy (2020) and was a Co-I on the AHRC funded Humphry Davy Notebooks Project. His Michael Faraday: A Very Short Introduction was published in 2010 by OUP who the following year also published his sesquicentenary edition of Faraday’s Chemical History of a Candle.  \nHis current research concentrates on writing and researching a biographical study of Humphry Davy focussing on his practical work including nitrous oxide\, agricultural chemistry\, mineralogy\, the miners’ safety lamp\, analysis of ancient Roman pigments and his attempts to unroll chemically the papyri excavated from Herculaneum.

SUMMARY:'Metroland - Engineering\, Economy & Social Change 1863-2026' by Dr Mark Pegg
DESCRIPTION:Image Credit: Lecturer’s copyright \nThis event is both an in-person and on-line event. No need to register – just come along or click this zoom link to join on-line. \nDr Mark Pegg discusses how one railway line changed London social and economic life by connecting city workers with the Chiltern Hills and beyond. The talk explores the civil\, mechanical and electrical engineering challenges of the steam powered and electric rolling stock\, that enabled trains to carry passengers and goods on steep gradients from London to Buckinghamshire while supplying the rapidly growing London market with coal\, fresh food and dry goods. \nMetroland was made more famous by Sir John Betjeman who wittily observed the change the railway brought to new London suburbs that grew up to provide homes in a rural environment with smoke-free air for London’s rapidly growing population\, particularly the workers who commuted daily into the heart of the City.\nThe phrase ‘Live in Metroland’ was coined by the Metropolitan Railway to promote the line in 1915 used until it became part of the London Transport Board in 1933. \nOpened in 1863\, the Metropolitan Line from Baker Street to Farringdon was the first underground railway in the world\, extending to Aldgate in 1876. At first\, it was strictly an inner-city line\, extension to Aylesbury in 1898 transformed the line into rural Buckinghamshire\, also sharing tracks with the Great Central’s ‘London Extension’ which ran into London Marylebone. Electrification went live to Rickmansworth in 1925 and later to Amersham and Chesham in 1961. Metroland is still changing today with more homes and the construction of HS2 and East-West the revival of the old Oxford to Cambridge ‘Varsity’ line. \nAbout the Speaker\nDr Mark Pegg read history at Oxford University where his published doctoral thesis was British Broadcasting and Society 1918-1939.  \nHe worked in the UK coal mining industry in deep mines and headquarters where he was the Chairman’s personal assistant and also researched the modern coal mining history. After working as a management consultant\, Mark became a Director of a Business School and CEO of the Leadership Foundation for Higher Education. He has extensive experience in the UK\, Europe\, Middle East\, Far East and Africa with clients including central governments\, Rolls-Royce plc and the UK Senior Civil Service.  \nMark is a Companion of the Chartered Management Institute and Fellow of the Chartered Institute of Personnel and Development.
