Trishna Sharma of Class XI Sc. came up with a new idea of disposing the plastic and converting it into the manure, solar car with vacuum cleaner and Piezoelectric transducer, solar train which was guided by Sri Sumant Kumar.

The Piezoelectric transducer is an electroacoustic transducer used for conversion of pressure or mechanical stress into an alternating electrical force. The piezo transducer converts physical quantity into an electrical voltage which is easily measured by analogue and digital meter. This can be implemented in the footpaths, parks, spot courts and the area have more physical movement.
