  5. Solar Water Heater

    1986/01/01 Hot water is not always necessary, and in warm climates it may be relatively easy to do without. It is, however, more effective than cold water for many purposes. Even so, in some areas hot water is not used because fuel is so expensive it is used only for essential tasks. A solar heater can...

  6. Understanding Solar Water Heaters

    1986/01/01 The easiest and most practical application of solar energy is for heating water. It has been technically feasible to heat household water using solar energy since the 1930's. Solar water heaters for homes and industry have been employed extensively in Israel, Australia, and Japan, and were quite...

  7. Solar Still

    1980/01/01 A solar still is a device that uses energy from the sun to purify salt- or brackish water. Solar stills (as shown in Figure 1) can be easy to construct and maintain. Depending upon their size, they can provide water for many uses. And in desert areas where sunshine is plentiful and water is not,...

  8. Understanding Solar Stills

    1985/01/01 Solar distillation uses the heat of the sun directly in a simple piece of equipment to purify water. The equipment, commonly called a solar still, consists primarily of a shallow basin with a transparent glass cover. The sun heats the water in the basin, causing evaporation. Moisture rises,...

  9. Understanding Solar Water Pumps

    1985/01/01 This paper examines water pumping systems that use solar radiation as a direct source of energy. We look primarily at small-scale rural applications in the Third World, where the potential benefits are greatest and the near-term economics seem most favorable. Two generic technical approaches for...

  10. Understanding Solar Energy

    1985/01/01 Developing countries are in a particularly good position to use solar energy because so many receive an abundance of sunshine. More important, the inhabitants of these countries are frequently scattered over vast areas, making access to electricity or conventional fossil fuels difficult as well...
