Filipino Student Turned Rotten Vegetables into Solar Windows

Not All Rotten are Forgotten.

Carvey Maigue, a student from Mapua University, proof that phrase is true after all. He has been listed for James Dyson Award 2020 for his new invention called AuREUS. This device is able to transform rotten fruit and vegetables into clean and renewable electricity.

So, what does AuREUS do?

AuREUS system uses crop waste, such as rotten vegetables and fruits, to absorb stray UV light from the sun and converts it to electricity. The system is installed in windows and walls of buildings, and it uses the same technology to imitate the phenomena of the Northern lights. High energy particles are absorbed by luminescent particles that re-emit them as visible lights.

The similar particles that are imitated from the rotten vegetables and fruits were suspended in a resin substrate. And when the sunlight hits it, the particles absorb and emit visible light along the edges, and the captured light can be converted to electricity.

AuREUS is one of the 1,800 other inventions from young inventors and design engineers from 27 countries from across the world. The criteria were none heavy, just “Design something that solves a problem.”

Young inventors met virtually to discuss the solution to the global problems. From all the entries, only 20 had been chosen to be potentially crowned as the International Winner, Sustainability WInner, or International Runners-Up by the James Dyson Foundation.

James Dyson himself will review each finalist. The winners will be announced on November 19.

“This year has brought massive challenges, and if one thing is certain, our top 20 inventors have shown that young minds and unfiltered curiosity need a seat at the table,” says Tom Crawford, the global director of sustainability. “There is always a need to solve problems, and the number and breadth of this year’s entries show that the future of invention is bright.”
