further chapters cover specific aspects of turbine types for hydro, not previously covered thoroughly by published material new title for successful Planning & Installing series

Micro-Hydro Design Manual has grown from Intermediate Technology's field experiences with micro-hydro installations and covers operation and maintenance, commissioning, electrical power, induction generators, electronic controllers, management, and energy surveys.There is an increasing need in many countries for power supplies to rural areas, partly to support industries, and partly to provide illumination at night. Government authorities are faced with the very high costs of extending electricity grids. Often micro-hydro provides an economic alternative to the grid. This is because independentmicro-hydro schemes save on the cost of grid transmission lines, and because grid extension schemes often have very expensive equipment and staff costs. In contrast, micro-hydro schemes can be designed and built by local staff andsmaller organizations following less strict regulations and using 'off-the-shelf' components or locally made machinery.

Highly illustrated and practical, Microhydro is the first complete book on the topic in many years. Covering both AC and DC systems, it first introduces the important principles on which microhydro is based, including the advantages and disadvantages of using small amounts of water to generate power. Along with a glossary of microhydro terms, further reading and resources - including websites and commerical suppliers - Microhydro includes all the information a homeowner needs to start generating clean, off-grid, and independent power.

This practical manual is a major new addition to the resources available for micro-hydro power project and programme managers worldwide and represents excellent value for such a detailed technical reference handbook.

This informaion package has been prepared to respond to an increasing number of requests for information on micro-hydro systems. It contains a resource directory, which is an attempt to put the reader in contact with the literature, plans, people, and companies appropriate to needs. On a world-wide basis, small-scale, environmentally benign, mechanical, and electrical hydropower systems are common. These are the systems for individual homes, farm, and shop use and generally have power outputs less than 100 kW. For convenience in terminology, this scale of hydro power is referred to as micro-hydro. A decision tree is first presented followed by information on determining the suitability of th site, equipment, economics, sources for financial assistance, regulatory conflicts, cautions and suggestions for the Do-It-Yourselfer, and the Self-Installer, manufacturers and suppliers, and sources of professional services. An annotated bibliography of 16 references is provided. (MCW).
