High Schoolers Awarded for Inventing Inexpensive Device That Generates Electricity From Sound
A team of high school students have developed an inexpensive device that can generate electricity from sound.
The eleventh grade students from the Philippine Science High School-Western Visayas Campus (PSHS-WVC) say that the generator is like the opposite of a standard musical speaker; rather than using power to emit sound, the inside of the speaker is equipped with magnets and coils that generate electricity whenever they are hit by sound waves.
According to the Manila Bulletin, their “S-Light” invention only cost about $4 (P200 pesos), most of which was spent on capacitors.
The gadget typically only generates enough electricity to power a small light, but it could prove to be an invaluable source of energy and lighting for rural communities.
Additionally, the device’s technology can be scaled up to generate larger amounts of energy from noisy areas such as airport runways.
The five students and their invention were awarded the Silver Award for the 2019 Young Inventors Challenge. They now hope to use their education and technological experience to further develop the device and use it to help the Filipino people.

When Joshua Aversano was hit and killed in a car accident, his sister Rebekah and her family were asked an impossible question, to donate his face to save the life of another man. Incredibly, they said yes. As a result, Richard Norris is probably the greatest medical miracle in the world right now. His face, bones, teeth, tongue, skin and hair are another man's – they belong to Joshua. Richard is the recipient of the world's first full face transplant. On 60 Minutes, Richard, his family, and his new love tell their remarkable story to Allison Langdon. And after 3 years, Rebekah Aversano meets Richard – the man who now wears her brother’s face.
