A comparison of quantitative and qualitative employment effects of solar and conventional systems can prove the increased employment postulated as one of the significant secondary benefits of a shift from conventional to solar energy use. Current quantitative employment estimates show solar technology-induced employment to be generally greater…

This manual on fasteners (devices used in home and shop to hold things together) is one of a series of power mechanics texts and visual aids on operation, diagnosis, and repair. Materials provide basic information and illustrations for use by vocational students and teachers as well as shop servicemen and laymen. Seven chapters are included: (1)…

Estimates from an interagency labor-demand model of energy-related employment in the next few years indicate that coal mining and power plant construction will provide most of the new jobs. (MF)

By building components at low cost and learning a whole course of metalworking in the process, students can build this mini-bike for maxi-learning. (Editor/MU)

Discusses the concepts of energy, flow of energy through ecosystems in which people live, our increasing use of energy as society evolves, and the importance of energy to all societies. A chart listing advantages/disadvantages of various energy sources is included. (JN)

Intended for nonspecialists, discusses various aspects of energy in historical terms. Areas addressed include brevity of the cheap energy era, exponential growth, and ideology/controversey (suggesting relationships between power plants and economic power). Examines general literature providing a framework for qualitative thinking about energy and…

Explains that the efficiency and the useful power available from a windmill turbine, of a laminar-flow model, will vary due to rotational kinetic energy of the downwind stream and turbulent mixing from outside the boundaries of the idealized stream. (GA)

Gives a brief description of open-circuit wind tunnels of rectangular cross-section and of how expanded polystyrene can be used to build a small one. (Author/GA)

Reviews the history of the steam turbine at sea from the 1880s to modern turbines. Presents several pictures of various types of turbines. (YP)

Describes four successful community programs dealing with waste management issues, developed with assistance from Keep America Beautiful System: litter prevention (Beatrice, Nebraska); composting yard waste (Centralia, Illinois); recycling (Lake Jackson, Texas); and waste-to-energy incineration (Gastonia, North Carolina). Notes related education…

Students live in a world that is powered by petroleum and other energy resources to an unsurpassed degree. The United States today consumes more than 24% of all the energy used in the world--and about 60% of this energy is provided by petroleum (oil and natural gas). The availability of abundant, inexpensive energy is the main reason that the…

The purpose of this booklet is to provide a basic understanding of nuclear fission energy and different fission reaction concepts. Topics discussed are: energy use and production, current uses of fuels, oil and gas consumption, alternative energy sources, fossil fuel plants, nuclear plants, boiling water and pressurized water reactors, the light…

The materials in this document are an extension of a catalog of occupational duties, tasks, and performance objectives relevant to maintaining automotive suspension systems, brakes, and steering mechanisms. This document provides the following for each occupational task within each duty: (1) a standard of performance; (2) the conditions under…
