Design and construction of a lens based solar water heater.

Abstract

The most common sources of energy for heating water include wood, charcoal, liquefied petroleum gas, fossils fuels and grid electricity. Due to increased need of energy, there too much dependence on energy from fossil fuels to meet the energy requirements. These emit carbon dioxide and other forms of pollution every second and the fossil fuels will eventually run out. Therefore, in order to obtain a clean and. sustainable energy that will not harm the environment, people are looking for eco-friendly alternative sources of energy such as solar and biodiesel. (Chu, 2011). The purpose of this project is to and construct a lens based solar water. heater for water heating for domestic purposes -like dish washers, clothes washers, bathing and cooking so as to reduce energy costs using a free energy resource use and reduce emissions of greenhouse gases into the environment. In order to achieve the above purpose, the methodology below was used; data collection which involved literature surveys and reviews, direct observations and. interviews, data analysis and design procedure, different construction techniques, testing the performance and economic evaluation of the proposed energy system. Once all these methodologies were met, the energy system was designed, constructed, tested and economically evaluated. The. implementation therefore reduces on energy consumption and conserve the environment.
