IIT Madras researchers develop technology to generate electricity from Sea Waves
Tags: Science and Technology
Indian Institute of Technology (IIT) Madras Researchers have developed an 'Ocean Wave Energy Converter' that can generate electricity from sea waves.
The trials of this device were successfully completed during the second week of November 2022.
The system, named 'Sindhuja-I', was deployed by the researchers about six kilometres off the coast of Tuticorin in Tamil Nadu, where the sea depth is about 20 metres.
Sindhuja-I can currently produce 100 watts of power. It will generate one megawatt of power in the next three years.
The research team plans to deploy a remote water desalination system and a surveillance camera at the location by December 2023.
What is Sindhuja-I system?
The system has been named 'Sindhuja-1', which means 'originating from the ocean'.
The system consists of a floating buoy, a spar and an electrical module.
As the wave moves up and down, the buoy moves up and down. In the current design, a balloon-like system called a 'buoy' has a central hole that allows a long rod called a spar to pass through.
The spar can be attached to the seabed, and passing waves will not affect it, while the buoy will move up and down and generate relative motion between them.
Relative motion drives an electric generator to generate electricity. In the current design the spar floats and a mooring chain keeps the system in place.
