APPROPRIATE TECHNOLOGY Ap pr o priat e Te c b n ol o g3r - A Dire cto ry of Actioities and Projects, Integrative Design Associates, l977,free from the National Science Foundation Research Applied to National Needs lVashington, DC 20550 Annotated listing of more than 300 U.S. groups and individuals who regard themselves as active in a.t. development. It contains a zip code listing of U.S. groups, a list of Washington, DC, resources, international activities in a.t., an introductory bibliography, and a report on what a number of a.t. people consider important issues to be deait with in the future. A bargain at twice the price. -TB Liklik Buk, Melanesian Council of Churches, 1977, $5 fuom' VITA 3706 Rhode Island Ave. Mt. Ranier, MD 20822 Real appropriate technology manuals need to be developed regionally-to sift through the stage we're in now of documenting, analyztng, testing and laying out simply for people what works for the special needs and opportunities of each region. This is a beautiful example prepared for community self-help in Papua. New Guinea, and in many ways is the finest a.t. publication we've seen. Not a lot of rhetoric-just a few warnings to a.t. people to practice instead of preaching-and a wonderful collection of lovingly presented how-to information-dressmaking, seif-propelled ferries, bush medicine, uses for oil drums, old tires and inner tubes. It also has an extensive section on agriculture and food processing. Simple, solid and dignifieda real bargain. -TB WATER/SEWAGE Chinese Cbain and Wasber Pumps, compiled by Simon Watt, ITDG, 1976, $3.50 from' ISBS P.O. Box 555 Forest Grove, OR 97116 An interesting compilation of 21 of the 120 versions of the chain and washer water-lifting devices developed by various communes in China and displayed at the 1958 Peking Agricultural Exhibition: Contains performance infofmation and descriptive drawings from which they can be built. Basic principles and potentials of the device, adaptation to various power sources, and construction from variopg local materiais. -TB New Directions in Solid Waste Planning, Neil Seldman,l977, $2.25 ftom' Institute for Local Self-Reliance 1717 lSth Street N.W. Washington, DC 2OOO9 An encouraging progress report on development and implementation of low technology solid waste recycling systems. Source separation programs in small towns and rural counties in Maine and New Hampshire have recovered up to 5O% of the waste stream, and other projects across the country have clearly demonstrated the technical, economic and social effectiveness of such systems. In contrast, highly touted high-tech resource recovery,plants have failed abysmally-with massive cost overruns, total technicai failures and frightening economics being common. Interestingly, a Department of Defense directive for waste recycling at military installations is expected to be a major stimulus to recycling, both by stimulating local materials markets and through allowing piggybacking by local communities on their transportation arrangements. Solid waste planning is at a breakthrough point, and it looks like the victor is common sense and common-sense.technology! -TB Jrily L977 RAIN Page 9 RIVER-POWERED FERRY -4 t- l-i-=--- To change the direction move the tow cable !o the other end of the horse: {"t e ,*td \ ) t. - nfta _ _ -. -___b_ .' Economically Appropriate Technologies for Deoeloping Countries, Marilyn Carr, ITDG, L976, $6.50 from' International Scholarly Book Service P.O. Box 555 Forest Grove, OR 97116 An excellent annotated bibliography from ITDG of almost 300 useful sources of both analytical studies of application of small-scale technologies in developing countries and of practical how-to information on equipment, processes and projects from various countries. Covers agriculture, low-cost building materials, manufacturing, infrastructure and various handbooks, manuals and technical publications. This sourcebook, in conjunction with Volunteers in Asia's Appropriate Te chn ologSt So urc e b o ok and our own R/INBOOK should pretty well cover the field of resources presently available internationally. The usefulness of this bibliography would be increased by inclusion of price and access information, as the difficulty of obtaining such materials is compounded when ordering from other countries. -TB Little E.C.S., A Kiln for Cbar' coal Making in tbe Field, Tropical Science, Vol. 14, 1972. Describes a new type of metal, transportable charcoal kiln known as CUSAB. This enables light, useless scrub to be rapidly converted into charcoal, which can be sold, e.g. for domestic fuel. By this technique, necessary bush clearing can proceed at a profit (a trial in Kenya cleared whistling thorn trees at a profit of 50 pence per acre for the whole operation); and large trees, conventionally used for charcoal production, can be spared. gat:! orga strb3o aa arllrto
