The Diffusion of Newcomen Engines, 1706-73: a Reassessment*
1 The Diffusion of Newcomen Engines, 1706-73: A Reassessment* By Harry Kitsikopoulos Abstract The present paper attempts to quantify the diffusion of Newcomen engines in the British economy prior to the commercial application of the first Watt engine. It begins by pointing out omissions and discrepancies between the original Kanefsky database and the secondary literature leading to a number of revisions of the former. The diffusion path is subsequently drawn in terms of adopted horsepower and adjusted for the proportion of the latter being in use throughout the period. This methodology differs from previous studies which quantify diffusion based on the number of steam engines and do not take into account those falling out of use. The results are presented in terms of aggregate, sectoral, and regional patterns of diffusion. Finally, following a long held methodology of the literature on technological diffusion, the paper weighs the number of engines installed by the end of the period in relation to the potential range of adopters. In the end, this method generates a less celebratory assessment regarding the pace of diffusion of Newcomen engines. *The author wishes to thank Alessandro Nuvolari for providing access to the Kanefsky database. Two summer fellowships from the NEH/Folger Institute and Dibner Library (Smithsonian), whose staff was exceptionally helpful (especially Bill Baxter and Ron Brashear), allowed me to draw heavily material from the collection of rare books of the latter. Two graduate students, Lawrence Costa and Michel Dilmanian, proved to be superb research assistants by handling the revisions made by the author to the database, coming up with the graphs, and running the tests involved in the third appendix of the paper as well as writing it. -

Assessing Steam Locomotive Dynamics and Running Safety by Computer Simulation
TRANSPORT PROBLEMS 2015 PROBLEMY TRANSPORTU Volume 10 Special Edition steam locomotive; balancing; reciprocating; hammer blow; rolling stock and track interaction Dāvis BUŠS Institute of Transportation, Riga Technical University Indriķa iela 8a, Rīga, LV-1004, Latvia Corresponding author. E-mail: [email protected] ASSESSING STEAM LOCOMOTIVE DYNAMICS AND RUNNING SAFETY BY COMPUTER SIMULATION Summary. Steam locomotives are preserved on heritage railways and also occasionally used on mainline heritage trips, but since they are only partially balanced reciprocating piston engines, damage is made to the railway track by dynamic impact, also known as hammer blow. While causing a faster deterioration to the track on heritage railways, the steam locomotive may also cause deterioration to busy mainline tracks or tracks used by high speed trains. This raises the question whether heritage operations on mainline can be done safely and without influencing the operation of the railways. If the details of the dynamic interaction of the steam locomotive's components are examined with computerised calculations they show differences with the previous theories as the smaller components cannot be disregarded in some vibration modes. A particular narrow gauge steam locomotive Gr-319 was analyzed and it was found, that the locomotive exhibits large dynamic forces on the track, much larger than those given by design data, and the safety of the ride is impaired. Large unbalanced vibrations were found, affecting not only the fatigue resistance of the locomotive, but also influencing the crew and passengers in the train consist. Developed model and simulations were used to check several possible parameter variations of the locomotive, but the problems were found to be in the original design such that no serious improvements can be done in the space available for the running gear and therefore the running speed of the locomotive should be limited to reduce its impact upon the track. -
Steam As a General Purpose Technology: a Growth Accounting Perspective
Working Paper No. 75/03 Steam as a General Purpose Technology: A Growth Accounting Perspective Nicholas Crafts © Nicholas Crafts Department of Economic History London School of Economics May 2003 Department of Economic History London School of Economics Houghton Street London, WC2A 2AE Tel: +44 (0)20 7955 6399 Fax: +44 (0)20 7955 7730 1. Introduction* In recent years there has been an upsurge of interest among growth economists in General Purpose Technologies (GPTs). A GPT can be defined as "a technology that initially has much scope for improvement and evntually comes to be widely used, to have many uses, and to have many Hicksian and technological complementarities" (Lipsey et al., 1998a, p. 43). Electricity, steam and information and communications technologies (ICT) are generally regarded as being among the most important examples. An interesting aspect of the occasional arrival of new GPTs that dominate macroeconomic outcomes is that they imply that the growth process may be subject to episodes of sharp acceleration and deceleration. The initial impact of a GPT on overall productivity growth is typically minimal and the realization of its eventual potential may take several decades such that the largest growth effects are quite long- delayed, as with electricity in the early twentieth century (David, 1991). Subsequently, as the scope of the technology is finally exhausted, its impact on growth will fade away. If, at that point, a new GPT is yet to be discovered or only in its infancy, a growth slowdown might be observed. A good example of this is taken by the GPT literature to be the hiatus between steam and electricity in the later nineteenth century (Lipsey et al., 1998b), echoing the famous hypothesis first advanced by Phelps-Brown and Handfield-Jones, 1952) to explain the climacteric in British economic growth. -
History of the Automobile
HISTORY OF THE AUTOMOBILE Worked by: Lara Mateus nº17 10º2 Laura Correia nº18 10º2 Leg1: the first car. THE EARLY HISTORY The early history of the automobile can be divided into a number of eras, based on the prevalent means of propulsion. Later periods were defined by trends in exterior styling, size, and utility preferences. In 1769 the first steam powered auto-mobile capable of human transportation was built by Nicolas-Joseph Cugnot. In 1807, François Isaac de Rivaz designed the first car powered by an internal combustion engine fueled by hydrogen. In 1886 the first petrol or gasoline powered automobile the Benz Patent-Motorwagen was invented by Karl Benz.This is also considered to be the first "production" vehicle as Benz made several identical copies. FERDINAND VERBIEST Ferdinand Verbiest, a member of a Jesuit mission in China, built the first steam-powered vehicle around 1672 as a toy for the Chinese Emperor. It was of small enough scale that it could not carry a driver but it was, quite possibly the first working steam-powered vehicle. Leg2: Ferdinand Verbiest NICOLAS-JOSEPH CUGNOT Steam-powered self-propelled vehicles large enough to transport people and cargo were first devised in the late 18th century. Nicolas-Joseph Cugnot demonstrated his fardier à vapeur ("steam dray"), an experimental steam-driven artillery tractor, in 1770 and 1771. As Cugnot's design proved to be impractical, his invention was not developed in his native France. The center of innovation shifted to Great Britain. NICOLAS-JOSEPH CUGNOT By 1784, William Murdoch had built a working model of a steam carriage in Redruth. -

In comparison with other counties, Cornwall was characterized by a relative high price for coal which was imported from Wales by sea.2 It is not surprising then that, due to their superior fuel efficiency, Watt engines were immediately regarded as a particularly attractive proposition by Cornish mining entrepreneurs (commonly termed ‘adventurers’ in the local parlance).3 Under a typical agreement between Boulton and Watt and the Cornish mining entre- preneurs, the two partners would provide the drawings and supervise the works of erection of the engine; they would also supply some particularly important components of the engine (such as some of the valves). These expenditures would have been charged to the mine adventurers at cost (i.e. not including any profit for Boulton and Watt). In addition, the mine adventurer had to buy the other components of the engine not directly supplied by the Published by & (c) The Newcomen Society two partners and to build the engine house. -

21 3 Steam Engine Governor Having a Close Approximation to Perfect Action
21 3 ON A SIMPLE CONSTRUOTION OF STEAM ENGINE GOVERNOR HAVING A CLOSE APPROXIMATION TO PERFECT ACTION. BY ME. JEREMIAH HEAD, OF MIDDLESBBOUGH. The irregularity of speed tolwhich all steam engines are liable arises from two principal causes : variation in the pressure of steam supplied, and variation in the amount of resistance to be overcome. Variation of steam pressure may arise from irregular firing, overtaxed boilers, or in the case of waste-heat boilers, from several dampers happening to be closed at once, and from other similar and obvious cauaes. Variation in resistance occurs when the work to be performed is from its nature intermittent ; this variation is at its minimum in such engines as those used for pumping or blowing, and at its maximum in engines such as are attached to saw-mills, rolling mills, grindstones and shears. If an engine readily lags in speed when the resistance increases, its efficiency is lessened just when most required ; and if it “runs away” when relieved of work, or when the steam pressure is higher than ordinary, the wear and tear of the machinery connected with it is increased, and at the same time steam is wasted in doing the mischief. These considerations were all fully recognised by Watt, who sought to remedy them by his well- known steam engine governor. Although imperfect and partial in its action, this governor is sufficient for many purposes; and its extreme simplicity has caused it to remain to the present time in more extensive use than any other. It acts on a throttle-valve inserted in the steam-pipe close to the valve-chest, and partly closes the throttle-valve when the normal speed is exceeded, and opens it wider when the speed falls below the ordinary rate. -

OXIDATIVE CHALLENGE TO AGING HUMAN LENS LEADING TO NUCLEAR CATARACT P.M.M. van HAARD TOELICHTING Het doel van het hier beschreven onderzoek is een beter inzicht te krijgen in het ontstaan van cataract o-F staar in de ooglens van sommige ouder wordende mensen. De lens stelt de mens in staat om scherp te zien. Een voor waarde is wel dat de lens licht doorlaat. Elke verandering in de lichtdoorlaatbaarheid ten gevolge van troebel worden van de lens wordt cataract genoemd. Oit betekent niet dat onscherp zien altijd aan cataract te wijten zou zijn. De lenstroebelingen, voorkomend bij oudere mensen (90-95% van alle cataracten) worden ouderdomscataracten genoemd. Tot deze groep van cataracten behoort de kerncataract ι het is de ze vorm van cataract die ik onderzocht heb. De kerncataract is om allerlei redenen een interessant onder- zoekobject. Komen bij andere ouderdomscataracten witte troe- belingen voor in verschillende delen van de lens, bij kernca taract wcrdt alleen het normaal lichtgeel gekleurde binnenste deel van de lens - de kern - meestal rond het vijftigste jaar steeds harder, troebel en bruiner van kleur. In het ernstigste en meest gevorderde stadium blijkt de harde, zwartbruine kern van de lens even groot te zijn als de lens bij de geboorte is.
