Most of the third world countries depend on agriculture to sustain their population and earn revenue through the export of their production to other countries. Agriculture requires the usage of water either from a river or through ground sources. Groundwater being dominantly available requires specialized tools to lift the water to the fields for the purpose of irrigation.
The present report focuses on the development of a water-lifting device that could an eco-friendly without compromising on the economic parameters of design. The objective is to achieve a fairly good amount of acceptable proportion in the design of water lifting device with regards to sustainability.
Two methodologies have been tested for the same. Use of naturally available sources of energy that can be renewed was made in the design of water lifting device. In areas, where sunlight or solar power was in abundance, solar powered devices were used to power up the pumps that lift water. In cases, where animal and organic waste was in abundance, design of power sources that work using organic waste as fuel was utilized. Two design strategies are tried out with regards to conditions prevailing in the testing areas. Two testing conditions were used. 1. Areas with surplus solar energy. 2.Areas with surplus organic wastes. .Help was solicited from the FAO Corporate repository for arriving at the design of the system. .In condition 1, the use of photovoltaic cells was adopted, refer to Figure 1 below. In both cases, a similar type of motor or pumps was used. . An array of photovoltaic cells was used to provide sufficient power to run a motor of a specified capacity (look for specifications in section 2). Care was taken in arriving at the best combination of photovoltaic cells. Since photovoltaics are costly and the amount of investment that goes into purchasing the units defeats the very objective of cost minimization in the short run, photovoltaics developed from locally available sources with good output were utilized. Please refer to section 2 for output specifications.
