A team of IIT Guwahati researchers has developed new materials that could be used to generate power from water, in both flowing and stagnant states.

A team consists of IIT Guwahati researchers has developed new materials that could be used to generate power from water, in both flowing and stagnant states. The researchers think that they could implement this technique on a small scale in households.

The team doesn’t follow conventional methods for producing electricity. Instead, they have a decentralized approach. And to be able to do this, the researchers make use of a nanoscale phenomenon known as “electrokinetic streaming potential” to generate power from flowing water. Meanwhile, they use a process known as “ contrasting interfacial activities” to harvest power from stagnant water.

This process uses doped graphene lakes. The power is then transferred by the additional charge. This is done by dipping the flakes in the water. Raidongia, a member of the team said:

In the research, the researchers separately mixed graphene oxide with nitrogen and boron. The two forms of graphene are then loaded into filter papers. The researchers then turn them into electrodes.

According to the researchers, by dipping the two filter papers, they could produce 570 millivolts. The electricity was stable for around 80 hours. Raidongia added that they improved the generated power by varying parameters such as coating area, annealing temperature, the medium’s ionic conductivity, and the extent of doping.

The researchers also said that they could still further improve and perfect the methodology. At the moment, they are focusing on optimizing the technique. The team does this by looking for a balance between nanofluidic confinement and high flow-rate.
