A little encouragement and even small, innovative experiments can help change the future. This has been proven by two school girls from the Government Primary School in Kalitheerthalkuppam village in Puducherry who built a mico-generator to produce power.
The Hindu report said that T Mithra and K Sharani Priya, both Class V students, went to visit the Puducherry Science Centre and Planetarium with their teachers and classmates when they noticed drainage water flowing fast near the Kurunji Nagar Modern Park.
They returned later to execute their experiment with the assistance of their teachers.
They measured the length and breadth of the drain and calculated the speed of flowing water. A 3-inch radius turbine was also built.
Sharani Priya told The Hindu:
Each blade in the turbine was bent 45 degree which makes the turbine rotate faster. The turbine was connected to a 100 rpm gear motor. When the turbine rotates one time, the copper coil inside the motor rotates for 100 times and produce electricity.
The power generated from the motor was between 8v and 9v which can be used to charge cell phones, glow LED lights and also play the radio.
