Low temperature geothermal springs for water pumping

Abstract: Low temperature geothermal springs, which account for about half the total known in India, have been mainly used for spas or other types of bathing. A suggestion has been made that the surface or subsurface hot water from geothermal springs could be used to energise solar pumps which otherwise use solar heated water. A comparison between these two types of device (solar and geothermal) indicates that the latter has two main advantages: (a) the capital investment is less (due to the absence of a solar collector array) and (b) there is non-stop, around-the-clock availability of energy and so a higher utilisation efficiency at all times and seasons. The fixed location of the springs is a major limitation. However, those located around agricultural fields or inhabited areas can be exploited fully.
