Grade 11 students from Western Visayas High-School invented a device that converts noise to electricity

The need for an alternative source of energy is rising fast as the world faces an emergency crises, caused upon by the exploitation of the non-renewable fossil fuels.Solar & wind energy have already been tapped as a source of renewable source of energy, and are now being accepted as one of the replacements for fossil fuels.

Lets consider this remarkable invention added to the renewable source of energy, from the young and fresh ideas of the Grade 11 students from Philippine Science High School-Western Visayas Campus (PSHS-WVC), which able to converts noise to electricity.

While you think that noise are useless and irritating, these students however are blessed that they have been able to create a device that they called Sound - Light or "S-Light". Team Voltage 5, composed of Grade 11 students Kirsten Dianne Delmo, Frelean Faith Engallado, Nico Andrei Serrto, Joecile Faith Monana, and Raphael Francis Dequilla are the young scientists behind this eco-friendly device. 

The device can be able to convert sounds into a viable source of electric power by converting vibrations caused by noise into electrical energy. The invention won the Silver Award during the Young Inventors Challenge 2019 in Malaysia. Although converting noise to electricity is not a new concept but still no infrastructure has been made applying this concept, according to the team quoted in Manila Bulletin report.

The project has costs them only P200 pesos which was spent on the capacitors. When sound waves hit the diaphragm of the speaker, the magnet and coil inside interacts that produces electrical energy, and stored into a power bank that could power up lights.

The group also shortlisted for the global competition in the National Aeronautics and Space Administration (NASA) Space Apps Challenge.
