ABSTRACT
The Fresnel lens is a modified magnifying glass which can be made from various materials like glass, acrylic and so on. However, due to the lesser weight of acrylic materials, even very large Fresnel lenses can have considerably less weight. This is one of the biggest advantages in tracking of the system. In this paper, a Fresnel lens of about 0.5 m2, retrieved from old projection TV was used as a solar collector and heat received from the sun was utilized for various applications like steam generation, high temperature reactions and waste water treatment. The results were highly encouraging.
Energy is a very crucial aspect for the growth of any country and at the same time environmental pollution is another big problem for the energy sector. Therefore, utilization of solar energy is an attractive path to solve both energy and environmental problems. This paper discusses the utilization of such solar energy by a using Fresnel lens recovered from a waste project TV. Some reported applications of Fresnel lenses are discussed in given references [1–4]. This work demonstrates a number of possibilities for the development of various solar thermal energy applications.
