Solar concentrator for water desalination

The aim of this book is to develop an alternative to better meet the needs of people who need drinking water in their homes. It presents a cylindrical parabolic concentrator. By experimenting with solar energy, we can see that it would be a viable alternative for many people. A solar concentrator is a device that directs the sun’s rays towards a certain region of the equipment called the focus. In the proposed parabolic solar concentrator, the focal region is made up of a glass tube made from materials resistant to high temperatures. The methodology developed was validated through its application in the city of João Pessoa, capital of the state of Paraíba, located in north-eastern Brazil. The results obtained from this application, as well as validating the methodology, brought to light important elements for discussing a simple and practical alternative for desalinating water and making it potable and suitable for consumption.
