328: Rotting Veg


One of the shortcomings in solar energy production is poor environmental conditions while vegetable waste needs to be usefully recycled.


AuREUS vegetable waste

Carvey Ehren Maigue, a 27-year-old engineer from Mapua University in Manila, the Philippines has developed AuREUS (=golden) a new fluorescent material made out of waste fruit and vegetables such as carrots that that can be attached to the sides of buildings to harvest invisible ultraviolet (UV). While ‘resting’, the particles remove excess energy, which bleeds out of the material as visible light and can be transformed into electricity.

The young engineer was inspired by the fact that UV light still seeps through on dark gloomy days when there’s not much sunlight that could potentially be harvested AuREUS could line the side of tower blocks to turn them into ‘vertical solar energy farms’ and power them for a fraction of the cost.

For his solution, in 2020, Maigue became the first-ever recipient of the £30,000 James Dyson Sustainability Award.
