  • 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.

A CATECHISM OF THE STEAM ENGINE IN ITS VARIOUS APPLICATIONS TO MINES, MILLS, STEAM NAVIGATION, RAILWAYS, AND AGRICULTURE. WITH PRACTICAL INSTRUCTIONS FOR THE MANUFACTURE AND MANAGEMENT OF ENGINES OF EVERY CLASS. BY page 1 / 559 JOHN BOURNE, C.E. _NEW AND REVISED EDITION._ [Transcriber's Note: Inconsistencies in chapter headings and numbering of paragraphs and illustrations have been retained in this edition.] PREFACE TO THE FOURTH EDITION. For some years past a new edition of this work has been called for, but I was unwilling to allow a new edition to go forth with all the original faults of the work upon its head, and I have been too much engaged in the practical construction of steam ships and steam engines to find time for the thorough revision which I knew the work required. At length, however, I have sufficiently disengaged myself from these onerous pursuits to accomplish this necessary revision; and I now offer the work to the public, with the confidence that it will be found better deserving of the favorable acceptation and high praise it has already received. There are very few errors, either of fact or of inference, in the early editions, which I have had to correct; but there are many omissions which I have had to supply, and faults of arrangement and classification which I have had to rectify.

G~NTLE~Z~.~":--Your attention is respectfully invited to the accompanying reports, as carefully prepared statements of the condition of the depar~tments to which they relate, and leaving but little to be said in addition. Since tile report of the department of Mining a~.t Metallurgy was put in type, Mr. Samuel Bachelder, of Cambridge, has presentedto the Institute his very ingenious dynamometer, which accurately weighs all the power transmitted through it. This will enable the department to keep an exact record of all the power used in the mining and metallurgcial laboratory in run- ning all or any of the machines in use. We have also received a Blake crusher, size 3 rF by 5", and a 12 inch Whelpley and Storer dry pulverizer. The new smelting and blast furnace~ have been fully designed by Pros Ordway~ and their construc- tion begun. Our thanks are due to H. J. Booth & Co., of the Union Iron Works, San Francisco, California, for a very large and generous reduction in the price of the machinery furnished by them; and it is but justice to I. M. Scott, Esq, of that fil~n, who designed and built the five-stamp battery now in our laboratory, expressly for the Institute, to say that it is complete in all its parts, and gives entire satisfaction.

NATIONAL MUSEUM BULLETIN 173 PLATE 1 SMITHSONIAN INSTITUTION UNITED STATES NATIONAL MUSEUM Bulletin 173 CATALOG OF THE MECHANICAL COLLECTIONS OF THE DIVISION OF ENGINEERING UNITED STATES NATIONAL MUSEUM BY FRANK A. TAYLOR UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 1939 For lale by the Superintendent of Documents, Washington, D. C. Price 50 cents ADVERTISEMENT Tlie scientific publications of the National Museum include two series, known, respectively, as Proceedings and Bulletin. The Proceedings series, begun in 1878, is intended primarily as a medium for the publication of original papers, based on the collec- tions of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and revisions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and scientific organi- zations and to specialists and others interested in the different sub- jects. The dates at which these separate papers are published are recorded in the table of contents of each of the volumes. Tlie series of Bulletins, the first of which was issued in 1875, contains separate publications comprising monographs of large zoological groups and other general systematic treatises (occasionally in several volumes), faunal works, reports of expeditions, catalogs of type specimens and special collections, and other material of simi- lar nature. The majority of the volumes are octavo in size, but a quarto size has been adopted in a few instances in which large plates were regarded as indispensable. In the Bulletin series appear vol- umes under the heading Contrihutions from the United States Na- tional Eerharium, in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum.

  • Steam Engine Collection
    STEAM ENGINE COLLECTION The New England Museum of Wireless And Steam Frenchtown Road ~ East Greenwich, R.I. International Mechanical Engineering Heritage Collection Designated September 12, 1992 The American Society of Mechanical Engineers INTRODUCTION It has been said that an operating steam engine is ‘visual music’. The New England Museum of Wireless and Steam provides the steam engine enthusiast, the mechanical engineer and the public at large with an opportunity to experience the ‘music’ when the engines are in steam. At the same time they can appreciate the engineering skills of those who designed the engines. The New England Museum of Wireless and Steam is unusual among museums in its focus on one aspect of mechanical engineering history, namely, the history of the steam engine. It is especially rich in engines manufactured in Rhode Island, a state which has had an influence on the history of the steam engine in the United States out of all proportion to its size and population. Many of the great names in the design and manufacture of steam engines received their training in Rhode Island, most particularly in the shops of the Corliss Steam Engine Co. in Providence. George H. Corliss, an important contributor to steam engine technology, founded his company in Providence in 1846. Engines that used his patent valve gear were built in large numbers by the Corliss company, and by others, both in the United States and abroad, either under license or in various modified forms once the Corliss patent expired in 1870. The New England Museum of Wireless and Steam is particularly fortunate in preserving an example of a Corliss engine built by the Corliss Steam Engine Company.
