In a stunning innovative feat, students from Pandit Ravishankar Shukla University in Raipur have produced electricity from polluted water.
The university’s bio-technology department had been working on this project for the last four years and have successfully generated electricity from polluted water discharged from industries. The study, which has recently been published in an international journal, was carried out by Dr. SK Jadhav, Alka Kaushik and Reena Meshram.
The researchers used industrially discharged polluted water to generate electricity to power a 4 volt bulb for 90 days and 12 volt LED bulb for 58 days. The researchers also used the generated power to charge the batteries of their mobile phones.
How it works:
The researchers made a series of anodes and cathodes out of a 650 ml plastic cylindrical bottle. The anodes were filled with bacteria and polluted water. The cathodes were then bridged with a buffer solution. The bacteria began to break down the carbons in the polluted water to generate electricity.
The researchers also believed that this method can be used to generate electricity commercially after developing microbial fuel cell. This type of electricity generation is cheaper than solar energy generation and is maintenance-free.
The water used for the experiment was collected from the rice mills in Urla-Siltara and Gudiyari areas of Jharkand.
