The objective of this research project was to design a device, which uses an airlift pump powered by solar energy to draw water. Farmers are the main constituents of the primary sector in most countries. Frequently farmers use excessive amounts of water, which not only harms the crops but also depletes the water table. In a world where there is a shortage of water, it is extremely important that we rely on specifically programmed devices that are simple to design, easy to use and are able to water plants in an efficient manner. Extensive use of such devices will help us to save precious water and may help solve the problem of world hunger through adequate farm produce. This concept can be also be applied in hydroponics, a method of growing plants in water, not soil, using mineral nutrient solutions. Due to rapid urbanization in various urban corridors where there is a large demand for fresh food, food can be supplied by hydroponics. Only 1. 361 kW/m²of the energy released by the sun actually reaches the planet. It is extremely important to make sure that we harness this energy. Solar energy is a renewable resource and using it would for sure help us reduce the global warming and help conserve bio fuels and other scarce resources. The use of solar energy provides flexibility in installation of such devices in places where electricity is not available. [2]
