l WIND Gemini Syncbron.ous Inverter Systems, by Windworks, Inc., 1978, 12 pp., photos, diagrams, graphs, table_s, free from: Windworks, Inc. . Rt. 3, Box 44A Mukwonago, WI 414/363-4088 All you ever wan.red to know about converting DC to AC power and feeding it back into your utilitie~• electric grid!. This beautifully illustrated brochure . covers how this is done using wind turbines, solar cells, solar thermal electric systems and small hydro-dai;ns,,with info on installation, safety, performance, power quality, utility interface, and load management. Extremely valuable in persuading a utility engineer since it includes a technical explanation of the electronic-electrical theories used and has such a professional look. Highly recommended for all pl,lhlic utility com-· missions, ·state energy officers and.windpower enthusiasts and users. -LJ The Energy Adventures'o[Ernie an' Bud: Build a Wind Generator, by ·Loren Schultz, 1978, 6 pp., 25<1 from: · AERO 43 5 Stapleton Bldg. Billings·, MT 59101 , Fantastic! You ca~'t imagine how d~ep and how long I chuckied a:fter reading along to the end of Bud an' Ernie's comic strip , finding that I cqµld then actually color and scissor together a • paper model of a wind-p.owered homestead. Outrageous. Very highly recommended for all overly serious wind energy:fanatics (like myself), for elementary school teaching, and for electric utility executives (see the batteries? see the Gemini DC-AC inverter?) Thanks, Loren. I needed that. What's next? -LJ I Pacific Northwest Regional Wind Energy Study, CRT-39, by James Peters<?,n and E. Wendell Hewson, March·,1',978,.-212 pp., 44 references, 57 figures; 49 tables, free while they last from: District Engineer Walla Walla District Corps of Engineers ' Bldg. 602, City-County Airport Walla Walla1 WA 99362 The greatest thing since sliced bread for the Pacific Northwest! Or at least until 1) the BPA-OSU r•eport on wind turbine farms integrated with the energy storage capability of the Columbia River hydroelectric dams, and 2) the GAO report on regional energy management come out. Although this srudy focuses on various combinations of windpower and pumped storage in Bonneville Power Administration territory, the interpretation of data make it·a model for other wind regions to emulate,. Of particular interest are the first equations I've seen that allow the calculation of the number of large wind generators that a given hydro-storage capacity, in dams or pum.ped storage, can accommodate in order to smooth (i.e. load-level) their variable output. Also, PNW wind data is analyzed to show the interacti.on of a number of wind farms working toget~er to produce,power, an a~e~ which is explored in greater detail m the BPA-OSl! Windpower Network Study. -LJ WOOD • Biomass Energy Success Stories: A Port[oliq Illustrating Current Economic Uses of Renewable Biomass Energy, HCP/TO285-0l, March 1978, 51 pp., free while supplies last from: July 1978 RAIN Page 17 Biomass Branch Office of the Ass't Sec'y for Ertergy Technology Dept. of Energy ~ashingt6n, .DC 20545 Bioma;s can provide direct proc'ess heat, or steam for process heat or.electricity. This booklet is a very well-illustrated, •semi-technical summary which covers project location, historical background, . energy recovery, economics and evaluation. Applications in many states and Canada, and in the sugar, pulp and paper, manufacturing, electric utilities and·, of course, wood products industries are included. Although an excellent series of appendices are used to give the ·reader a feel for the future potential of bioconversion, an expanded version • should include more examples at both the smaller and larger ends.of the enduse scale: from homes, small businesses, commercial esta,blishments·to large-scale • wood-powered utility power plan~s now -in use in Vermont. -LJ (Report courtesy Dick Durham, DOE-Richland) • Barnacle Parp's Chain Saw Guide, by Walter Hall, 1977 from: Rodale Press 33 E. Minor' Emmaus, PA,18949 'One of the most difficult accomplishments that could be attempted is writ- . ing a book on a specific,.subject that is useful to both neophytes and experienced old-timers. This book has done an excellent job at that, explaining how 'to buy, use and maintain, as well as sharing innumerab.le,safety tips and chainsaw hints,i.att-0f which will save you dollars and e~.tisternation. Quality diagrams and hutnerous illustrntions. make this an excellent reference, and a real must for present chainsaw users or prospective buyers.
