Material produces energy from rotten vegetables

Created by engineer Carvey Ehren Maigue of Mapua University in the Philippines, the project called AuREUS (Borealis Solar Windows and Astralis Solar Wall) captures solar energy through a flexible material, created from leftover vegetables and rotten fruits. 

It is known that one of the limitations of solar energy capture is that photovoltaic cells do not have the ability to capture high-energy ultraviolet lights. However, Carvey’s idea was to place the material on a surface to obtain ultraviolet light and convert it into visible light to thus generate electricity. 

That is, instead of trying to convert direct ultraviolet light into electricity, the engineer decided to turn visible light, and then capture the photons using conventional solar cells.

Carvey, who was one of the winners of the James Dyson Award, says he still intends to improve the project so that the process of extracting luminescent particles reaches 100% (currently 80%) from fruit and vegetable dyes instead of chemicals.
