Teens develop washing machine with junk, runs without electricity

In a drive towards raising awareness about environmental issues, two teens, Sourabh Siyal and Tushar Agarwal, have developed a washing machine made out of junk material. The machine, named ‘Eco-wash’, runs on mechanical and kinetic energy, without the use of electricity.

"The main washtub is built with junk materials like discarded plastic bottles and a pulley is attached to the plastic bottle to run the machine. The pulley moves with the help of kinetic energy and helps to wash clothes," explains Agarwal, who wants to be a scientific innovator.

"Our idea is to do away with electricity and come up with an alternative. The washing machine can be useful in big textile industries. We're planning to give our idea to one of India's leading garment manufacturing units," says Siyal, who too wants to pursue research work in the field of science.

In another such showcase of innovation four students of from a school in Bangalore, under the guidance of their Physics teacher developed an 'Earthquake predictor'. "The earthquake predictor is nothing but a borewell. The borewell is attached to a buzzer. The buzzer makes sound if the underground water level increases, which means that the movement of lava in the underground is moving at a faster rate, an indication of the likelihood of an earthquake. The fast movement of lava will force the water level to increase, which in turn will make the buzzer give out signals," said Subramanian K, one of the students.
