Solar Geyser Using Spot Fresnel Lens

[摘要] Fresnel lens based concentrating devices are not only gaining scope in the Photovoltaic industry, but also in solar thermal based industries. Fresnel lens is an optic device which concentrates the incoming light onto a spot or onto a line. This means that the temperature at that point will be significantly high. Utilizing this temperature for solar thermal applications will definitely be helpful for solar thermal power plants as the water can directly be converted into steam. This paper discusses about the various applications of Fresnel lens and how advantageous it can be to be utilized in solar thermal applications. Also better improvement on the collector design is projected that shows improvement in the overall performance of the system.
