What's New in India's Energy Sector?

The year 2003 was a momentous one for the energy sector in India, marked by two important and distinct developments. First, the legal framework governing the electricity sector was completely changed to make way for more progressive enabling legislation that would eventually enable a complete restructuring of the electricity sector and support greater private participation and growth in various aspects of generation, transmission, and distribution. Secondly, liquefied natural gas (LNG) achieved the status of a viable source of natural gas to fuel power generation and fertilizer industries with the completion of the first LNG import and regasification facilities. The opening of exploration and production of petroleum to private participants has started to give dividends as discovery of two large gas fields off the eastern coast of India has led to formulation of plans for a national gas pipeline grid to enable the gas to reach existing markets in northern and western India. This article seeks to discuss these major developments and also to evaluate the expectations surrounding them.

Dynamics of Tourism Development and Aspects of Sustainability: A Case Study of Ladakh

In a region like Ladakh which is an arid, high altitude, ecologically fragile, strategically located, culturally rich but sensitive area known for its unique Tibetan Buddhist culture, tourism was abruptly introduced with inadequate planning primarily to foster economic development and growth. In a short span of about two-and-a-half decades the self-sufficient agricultural economy following the barter system of trade has been converted to a cash economy, with a high dependence on the tourist industry for revenue and employment generation. It has also resulted in the degradation of physical and socio-cultural environment, which is the prime attraction for tourists. If this trend continues tourists will no longer be motivated to visit this region thus adversely impacting the tourism industry and consequently the economy of the region. Ways have to be found where tourism and environment can co-exist without damaging each other. The need of the hour is to formulate, develop and implement a pragmatic policy of sustainable tourism with the help and active participation of the local community by adopting the ‘bottom-up’ approach.

Recent Developments in the New Zealand Geothermal Industry

In New Zealand, geothermal energy is used mainly for the generation of electricity. Recently, major changes have occurred within the geothermal sector as a result of deregulation of the electricity generation and supply industry. A new power station, McLachlan (55 MW installed capacity) on the Wairakei field has been built and commissioned; this station operates on a load following basis. Construction of another new station, at Rotokawa field, has been completed; construction of a further station, at Mokai field, will begin soon. Many private companies and local suppliers are now applying for environmental permits for small scale (<100 MW) developments. It is predicted that geothermal energy will, in the future, provide an increasing proportion of electricity generation, rising from the present 6% to about 11% by the year 2020.

Power and energy [Technology 1998 analysis and forecast

Worldwide, as the power generation and electricity delivery industries are transformed by converging interests with gas and telecommunications, many emergent energy companies are seeking to present themselves as environmentally conscious. One stratagem is to offer a "green" energy package-that is, a deal permitting consumers to earmark a portion of their payments for renewable energy sources. But what some call a meaningful approach, others deride as just a sop to "politically correct" opinion. Near-term, the approach taken to limit greenhouse gases in the fastest-growing Third World countries will depend heavily on the fate of some very large dam projects, most in Asia and most hanging more or less in the balance. If those projects proceed on schedule, they may do much to lessen future reliance on hydrocarbon fuels. But large dams incur large environmental costs of other kinds, besides costing a lot, affecting many people adversely, and introducing special mega-risks. They are running into a global environmentalist backlash akin to the antinuclear wave of the late 1970s and early 1980s. The Three Gorges project and the environmental implications associated with it are discussed as are other large dam projects. The green energy package, new transmission and distribution technology are also discussed.

Results of the three-dimensional integrated circuits project in Japan

As the main theme of the Japanese national projects, the Three-Dimensional Integrated Circuits Project was initiated in 1981 to develop the most significant basic technology which is indispensable to the establishment of electronics and related industries for the next generation. This project was completed in 1991. The research and development were advanced by the collaboration of Electrotechnical Laboratory and seven private companies. The outline and noteworthy results of the project will be described in the following section.

An Introduction to the Design and Behavior of Bolted Joints

Abstract Although the title of this book includes the word “introduction”, the treatment of the subject is extensive and complete. The material goes well beyond the coverage of bolted joint design received in a typical undergraduate machine design course. The easy-to-read text begins with the fundamentals of bolt strength, deformation, and material selection and proceeds to cover the topics of preload, torque, and stretch control. The emphasis is on practical considerations for the efficient design of joints, including cost, ease of assembly, inspection, and disassembly. This second, revised edition has expanded the coverage of corrosion, fatigue, gaskets, and ultrasonic measurement of bolt strain. Also included are discussions of the failure modes and mechanisms of bolted joints. Case histories from industry are presented throughout the text to illustrate key points. Many up-to-date references are presented at the end of each chapter to allow the reader to pursue individual topics further, if desired. The text contains several appendices with useful tables and formulas for quick reference. The author has broad experience in the subject area from many years as a consultant to the power generation and nuclear industry, active participation on society working groups such as ASME and PVRC, as well as the presentation of numerous seminars on the topic. This book would serve as a valuable desk reference for engineers concerned with the design and performance of bolted joints.

The Temporal and Spatial Aspects of Diffusion of Technology

The contemporary theorizing on the diffusion of technology in terms of innovation-imitation distinction is the point of departure of this paper. The alternative viewpoint that the diffusion of technology is intimately linked with its development is advanced. The process of diffusion is best conceived in terms of the actual substitution of a new technique for the old. This viewpoint is further developed and operationalized in the form of two testable models of technological substitution. Several alternative derivations of these models are presented. The models have been applied to ten cases of adoption of new techniques in electricity generation, farming, manufacturing, steel production, and textile industries. There generally tends to be significant interindustry differences in the rates of diffusion of technology. Further, substitution of a new technique for the old generally takes place in the form of a significantly disproportionate growth in the use of the former as compared to the latter.
