IIT Researchers Focus on Hydropower Generation at Household Level

Hydropower Generation at Household Level

There has been increasing demand of energy worldwide, with the increasing population every day. To meet the requirement, scientists and researchers are trying to come up with the new ways. Harnessing energy from wind and water, Hydropower Generation are few examples of such trials.

For now, we have a concept of centralized source of energy. The energy generation occurs at a point, which later, spreads to other branches. This also result in loss of energy during transmission. Hence to overcome this loss, researchers from IIT Guwahati have come with the concept of decentralization of energy sources.

To support decentralization of energy, researchers are employing new technologies in every household. The small Hydropower generation devices will help in the generation of energy. End users can use the excess energy in nearby areas.

Similar to the case of centralization of energy, scientists are trying to harvest energy from water. In case of decentralization of energy, water will be the source of electrokinetic energy.

Technologies Supporting Decentralization of Energy

‘Electrokinetic streaming potential’ is a nanoscale phenomenon that will help in harvesting energy from flowing water. The technology works for water flow on small length scale. Hence, it can work on water flowing from household water taps. Further, ‘Contrasting Interfacial Activities’ is another concept to support the decentralization of energy at household level. The semiconductor based technology enables the production of energy from stagnant water.

To extract energy from still water, graphene flakes doping is done on the device. The charge transfer property of graphene flakes helps in power generation only by dipping in water. Power can be generated by dipping the device in any kind of water source such as river, lake and sea.

However, further research is going on to refine the energy production. The researchers claim that the power output holds chance of improvement by thousand times. For that, they are implementing the concept of biconical nanofluidic channels.
