“We are using the velocity of the flowing river to turn a turbine, and generate power,” said Saini, a  professor at IIT Roorkee. Hydro-kinetic technology has  significant advantages over other types of renewable energy, researchers said.


SCIENTISTS at IIT Roorkee are testing a floating device that can generate electricity from flowing surface water of rivers and streams, paving the way for an alternative source of renewable energy. Traditional hydropower plants require the construction of large-scale dams, which have significant ecological and environmental consequences. To counter this, a team at Indian Institute of Technology (IIT) Roorkee is testing a prototype that harnesses energy from flowing surface water. “In traditional dams, water falling from a height is used to turn turbines,” said R P Saini, the principle investigator of the project. “We are instead using the velocity of the flowing river to turn a turbine, and generate power,” said Saini, a professor at IIT Roorkee.


Hydro-kinetic technology has significant advantages over other types of renewable energy, researchers said. “Flowing water can generate hundred times more power than wind of same velocity,” said Saini. “The interest of Government for last 3-4 years is more on solar energy, because it is a modular system that can installed in  |four months and sunlight is available everywhere,” said Sunil Kumar Singal, head of the Alternate Hydro Energy Centre (AHEC) at IIT Roorkee. “But, the problem with solar energy at present is that on cloudy days and during the nights, we would need alternate source as currently energy storage systems are not efficient enough,” he said.


The prototype, developed in collaboration with Delhi-based Maclec Technical Project Laboratory, has been installed in the Upper Ganga Canal in Roorkee, Uttarakhand for testing. “In this canal, water discharge is almost constant throughout the year. Thus we have near ideal conditions for the purpose of testing,” said Saini.
