This floating device by IIT Roorkee claims to generate electricity from river surface

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 the Indian Institute of Technology (IIT) Roorkee is testing a prototype that harnesses energy from flowing surface water.

Alternative source of renewable energy

“In traditional dams, water falling from a height is used to turn turbines,” said RP Saini, principle investigator of the project.

“We are instead using the velocity of the flowing river to turn a turbine and generate power. Flowing water can generate a hundred times more power than wind of same velocity,” added Saini.

Hydro-kinetic technology has significant advantages over other types of renewable energy.

The researchers said that while there are many types of turbines currently under development, installing them in a flowing river is a tedious task.

“That is where more research is needed. Keeping that in view we have taken up this project to develop a prototype so that the installation can be standardised in the flowing canals and rivers,” Saini said.

The prototype, developed in collaboration with Delhi-based Macules Technical Project laboratory, has been installed in the Upper Ganga Canal in Roorkee, Uttarakhand for testing.
