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. -

More than 3.7 bil- Sean D. Logan, Director lion tons of Ohio coal has been mined since 1800, and recent DIVISION OF GEOLOGICAL SURVEY fi gures indicate that Ohio is the 3rd largest coal-consuming Larry Wickstrom, Chief state in the nation, consuming about 62 million tons per year. Ohio ranks 13th in the nation in coal production, and 7th in terms of demonstrated coal reserves with approximately 23.3 billion short tons, or 4.7% of the nation’s total coal reserves. (“Demonstrated Coal Reserve” is a term used to identify the part of the total resource that is potentially mineable when considering economic, legal, and engineering constraints). At present production levels, Ohio has more than 500 years worth of potentially mineable coal remaining. GEOLOGY OF COAL Th e coal-bearing rocks of Ohio were deposited during the Pennsylvanian and Permian Periods, approximately 320 to 245 million years ago. During Pennsylvanian time, or the great Coal Age, a shallow sea covered central Ohio. A series of river deltas extended into this sea carrying sediments that eroded from the ancestral Appalachian Mountains and fl owed northwest into the deltas. Extensive freshwater and brackish-water peat-forming COAL ecosystems formed in these low-lying coastal and near-coastal deltas, which were similar to those of the current Mississippi and Amazon Rivers. Th ese peat swamps remained undisturbed for thousands of years. -

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. -

Gas Migration from Closed Coal Mines to the Surface. Risk Assessment Methodology and Prevention Means
Post-Mining 2005, November 16-17, Nancy, France 1 GAS MIGRATION FROM CLOSED COAL MINES TO THE SURFACE. RISK ASSESSMENT METHODOLOGY AND PREVENTION MEANS Zbigniew POKRYSZKA1, Christian TAUZIÈDE1 and Candice LAGNY1, Yves GUISE2, Rémy GOBILLOT2, Jean-Maurice PLANCHENAULT2, René LAGARDE2 1 INERIS, Parc Technologique ALATA - BP N°2 - 60550 Verneuil-en-Halatte – France; [email protected], [email protected]. 2 Charbonnages de France, 100 avenue Albert 1er - BP 220 - 92503 Rueil-Malmaison - France, [email protected], [email protected] ABSTRACT: French law as regards renunciation to mining concessions calls for the mining operator to first undertake analyses of the risks represented by their underground mining works. The problem of gas migration to the surface is especially significant in the context of coal mines. This is because mine gas can migrate to the earth's surface, then present significant risks: explosion, suffocation or gas poisoning risks. As part of the scheduled closure of all coal mining operations in France, INERIS has drawn up, at the request of national mining operator Charbonnages de France, a general methodology for assessing the risk linked to gas in the context of closed coal mines. This article presents the principles of this methodology. An application example based on a true case study is then described. This is completed by a presentation of the preventive and monitoring resources recommended and usually applied in order to manage the risk linked to gaseous emissions. KEYWORDS: gas, coal, mine, closure, risk. RESUME : La réglementation française en matière de renonciation aux concessions minières prévoit que l’exploitant minier réalise au préalable des analyses des risques présentés par ses travaux miniers souterrains. -
