The Indian Institute of Technology Madras, or IIT Madras, has developed a solar ‘parabolic trough collector’ (PTC) system for concentrating solar energy for industrial applications like desalination, space heating and space cooling.

The PTC is lightweight and has been developed to have high energy efficiency. It is designed to function under India’s various climatic and load conditions, said a statement issued by IIT Madras.

The research was led by Prof K Srinivas Reddy, Heat Transfer and Thermal Power Laboratory, Department of Mechanical Engineering, IIT Madras and his team member Mr C Ananthsornaraj.
