  1. Understanding Stirling Engines

    1984-01-01 Stirling engines are external combustion engines that use air or other gases as working fluid. They can burn any solid or liquid fuel as their heat source. This makes them very attractive, particularly in situations where conventional fuels are expensive and hard to obtain. Because some types of...

  2. Low Cost Development Of Water Power Sites

    1987-01-01 Flowing water tends to generate automatically a picture of "free" power in the eyes of the observer. But there is always a cost to producing power from water sources. The cost of developing low-output water power sites should be checked against available alternatives, such as: Electric Utility -...

  3. Understanding Solar Cookers And Ovens

    1985-01-01 In many equatorial regions, native trees and bushes are being cut at an alarming rate to meet the growing demands for agricultural land, industry, and fuelwood and charcoal. The environmental consequences of this deforestation are severe, ranging from soil erosion and climate changes to flooding...

  4. Understanding Hydropower

    1984-01-01 Once it is understood that gravity and water can be harnessed to produce energy, a study of methods to extract this energy efficiently can be undertaken. The purpose of this paper is to discuss several such methods in general terms. The paper provides a basic introduction to the science of water...

  5. Understanding Mini-Hydroelectric Generation

    1985-01-01 Electricity can be generated from the power of flowing water. This is called hydroelectric generation, and it can be done anywhere that there is water and a hill or drop for it to run down--in an irrigation canal, where a river runs through rapids or over a waterfall, or where a dam has backed up...

  6. Understanding Pedal Power

    1986-01-01 Over the centuries, the treadle has been the most common method of using the legs to produce power. Treadles are still common in the low-power range, especially for sewing machines. Historically, two treadles were used for some tasks, but even then the maximum output would have been quite small,...

  7. Understanding Batteries

    1985-01-01 Batteries have been in use for many years, but today there is a greater demand for battery power than ever before. This renewed interest has been brought about not only by new developments but also by the diversity of uses for batteries in civilian, industrial, and military applications. This...

  8. Biogas Systems In India

    1983-01-01 This study is an assessment of the "appropriateness" of biogas technology in meeting some of the needs of India's rural population. Such an assessment is quite complicated, despite claims that a biogas system is a simple village-level technology. While there is evidence that biogas systems have...

  9. Waste Oil-Fired Kiln

    1984-01-01 This technical bulletin briefly describes a new technique for using the spent lubricating oil removed from automobiles. This oil normally has no immediate use. It is often discarded in ways that can foul local groundwater or upset wastewater treatment systems. The "waste oil" can be burned as...

  10. Baked, Leavened Breads

    1991-01-01 This profile describes a small bakery operating with a single shift and producing 100 tons of baked products a year. It also describes a medium-sized plant operating on the same basis but producing 250 tons of baked goods a year. Dry materials are received and water added to make dough, which is...
