Innovative Science Expo at Coimbatore

COIMBATORE: Two students of a city school have come out with an experiment of converting kinetic energy produced by the movement of a person sitting on a chair into electrical energy.

Naveen Kumar K and Shri Sakthi V of Sri Ramakrishna Matriculation Higher Secondary School exhibited their novel idea at the two-day Lead India Science Exhibition for School Students held at the Avinashilingam University in the city on Sunday. This project was among the six others selected to be displayed for A P J Abdul Kalam's visit on Sunday.

"A person sitting on a chair may make some movements. With each movement, there is motion of particle that causes vibration and produces kinetic energy," said Naveen Kumar. "This kinetic energy can be converted into electrical energy," he said. The project also won the second prize under the resources and renewable energy category.

A project by Pawan Kumar Mitruka V and Rahul Prasad Jaiswal from Kikani Vidhya Mandir won the first prize under the community health and hygiene category. It displayed ways of production of bio-fuel from industrial effluents.

"A major part of industrial effluent contains acid oil. We have used carbinol and sodium hydroxide to produce the bio-fuel from the industrial effluent," Pawan Kumar said

The end product of the experiment contains oil (bio-fuel) and glycerin which are separated by filtration and could be used in pharmaceutical industry, Jaiswal said.

Out of the nine government schools participating in the competition, R C Government Girls Higher Secondary School, Ondipudur sketched out a plan to revive the water bodies in the city. They won the first prize under the category of reclamation of water bodies in Coimbatore.

Around 180 projects were displayed by teams from 64 schools at the exhibition. A panel of external judges scrutinized the exhibits under the four themes - reclamation of water bodies in Coimbatore, resources and renewable energy, rain water harvesting and community health and hygiene.

A total of 24 projects were selected to be displayed on Sunday and two under each category were rewarded.
