BENGALURU: Innovative exhibits on water purification and energy conservation were on display during Anveshan 2015, a three-day science and engineering fair in the city, which concluded on Friday.
The event showcased about 50 exhibits, each jointly developed by a team of undergraduate engineering students along with two students drawn from government high schools.
A low-cost filtration process to remove fluoride from ground water in villages was exhibited by the students of Sapthagiri College of Engineering. Elaborating on the process, project team leader Rajeev Roshan, a third year student, said their device costs just Rs 750, against conventional filters which cost between Rs 4,000 and Rs 12,000. “Tricalcium phosphate is used to remove flouride content in this filtration process,” he said.
It was a team effort by Roshan’s classmate V Aishwarya, and Suryaprakash P and Venu N, Class 9 students of the Government High School at Bagalkunta.
A solar tree-cum-wind mill for 24-hour electricity generation, designed by the mechanical engineering students of R L Jalappa Institute of Technology, Kodigehalli, too was displayed. It was a tree-shaped structure with a small windmill on top with metal and steel rods for branches. About 150 small solar cells connected to a battery were placed on top.
The event was organised by Agastya International Foundation.
