Page 8 ENERGY continued from page 7 Structural Analysis of Wind Turbine Rotors for NSF-NASA Mod-O Wind Power Systems, by David Shea for NASA Lewis Research Center. $3.75, NASA TM-X-3198 from: N.T.I.S. Springfield, Va. 22151 . Presents preliminary estimates of v1bratory loads and stresses in hingeless and teetering rotors for proposed 100-kw wind power system. Report gives stresses in the shank areas of the 19 meter blades for static, rated and overload conditions. Power from the Wind, 1948, 1974, by Palmer C. Putnam. $9.95 hardbound from: Van Nostrand Reinhold Co. Litton Educational Publishing 450 W. 33rd St. New York, N.Y. 10001 In 1941 a large 17 5 -foot diameter, twobladed wind turbine was designed, fabricated and erected on Grandpa's Knob, a 2000' high mountain near Rutland, Vermont. Called the Smith-Putnam, it produced electricity for the Central Vermont Public Service Company's network at a cost close to that of today's nuclear/fission power plants. Putnam, an engineer and consultant to the U.S. government on renewable energy sources, describes the experiment from start to finish, in what is now the definitive and classic work on the planning and design of megawatt wind-electric systems. There stand today mighty wind mills, built because of this book, that are models of what we ourselves could do as individuals, if we wished. To be read with Prof. E. Wendell Hewson's The Windpower Potential in Selected Areas of Oregon (free, Atmospheric Sciences Dept. OSU, Corvallis, Or. 973 31). A Nation of Energy Efficient Buildings by 1990. Free from: The American Institute of Architects 1735 New York Ave., N.W. Washington, D.C. 20006 In their earlier report, Energy and the Built Environment: A Gap in Current Strategies, the AlA concluded, "We are now investing vast quantities of increasingly scarce capital resources in strategies which have less potential, less certainty and longer-delayed payoffs than an alternative strategy emphasizing a national program for energy efficient buildings." This new report shows how such a program can be economically, financially and administratively feasible, and presents recommendations for immediate action. Ask for a publications list. The state of Oregon has been using less energy, but the costs are still rising. For example, five state buildings on the Capitol Mall-the Capitol Building, Public Service Building, State Library, Labor and Industries Building and Highway Buildingused a total of 1,016,000 kilowatt hours during February 1975, a 20 percent drop. However, the state's power bill for the five buildings was $7,620 in February 1973, and $8,976 in February 1975, despite the smaller amount of power used. New Alchemy West P.O. Box 376 Pescadero, Ca. 94060 Most recent of their newsletters, Methane Digesters for Fuel Gas and Fertilizers, $3.00. Put together by L. john Fry, Richard, Yedida Merrill.

Environmentally Appropriate Technology: Developing Technologies for a Conserver Society in Canada. March 1975, by Bruce McCallum Advanced Concepts Centre Office of the Science Advisor Environment Canada Ottawa, Canada K1A 043 91-page primer for government policymakers on how a new school thought evolved from the environmental movement, the back to the land movement and biotechnics (life supporting technology); how renewable energy sources were re-discovered and how they can be put to best use in architecture, agriculture, transportation. Biomass energy, sailing ships, housing design, flywheel energy storage, clivus multrum, telecommunications, Darrieus windrotors, heat pumps, all the options in the transition to a future conservationoriented society.

Solar Energy Newsletters Solar News & Views, monthly International Solar Energy Society News (ISES), quarterly Solar Energy journal, quarterly $20 per year for all three from: Dr. W .H. Klein, Secy-Treas ISES, American Section . Smithsonian Radiation Biology Lab 12441 Parklawn Drive Rockville, Md. 20852 $20 yearly membership dues in ISES brings the American section newsletter, with 8 pages on U.S. local chapter activities, conferences, educational seminars, expositions, book reviews; the 8-page ISES News with international coverage, solar energy history; and the journal with in-depth technical and academic studies by solar scientists, engineers, architects, inventors and economists the world around. A very good deal but please be patient. Membership has recently gone through the top of the charts. These are the people who can tell you how to organize a local chapter in your town. The American section is now compiling a directory listing members and their solar energy interests. Solar Energy Digest, by William B. Edmondson. $27.50 per year, monthly, from: Lillian B. Edmondson, Circulation Manager S.E.D. P.O. Box 17776 San Diego, Ca. 92117 (714) 277-2980 The first and most widely read, started by the Edmondsons before the sun looked better as a result of energy crisis rising prices. Emphasis on all solar techniques, including wind and biomass conversion; covers only the most important legislation on all levels. Attention devoted to hand tools and reference books for the backyard "do-it-yourselfer" is unique and extremely useful.
