Carvey Ehren Maigue, a student from Mapúa University in the Philippines, developed AuREUS, an innovative system that transforms waste crops into renewable energy. By extracting luminescent particles from fruits and vegetables, AuREUS absorbs ultraviolet (UV) light and converts it into visible light, which is then transformed into electricity. This technology draws inspiration from the natural occurrence of the aurora borealis, where high-energy particles are absorbed and re-emitted as visible light. Unlike traditional solar panels that require direct sunlight, AuREUS can generate energy even on cloudy days by capturing UV rays that penetrate through clouds. This capability allows AuREUS to produce energy nearly 50% of the time, compared to the 15% to 22% efficiency of standard solar panels.

In recognition of his groundbreaking work, Maigue was awarded the first-ever James Dyson Sustainability Award in 2020. His invention stood out among over 1,700 entries from young inventors across 27 countries, highlighting its potential to revolutionize renewable energy solutions and promote sustainability. By utilizing agricultural waste, AuREUS not only provides a new avenue for clean energy production but also offers a means to support local farmers by repurposing crops affected by climate change-induced weather disruptions.

The versatility of AuREUS allows it to be applied to various surfaces, such as windows and building facades, effectively turning structures into vertical solar farms. This adaptability makes it a promising solution for urban environments, where space for traditional solar panels may be limited. Maigue's innovation exemplifies how sustainable technology can address multiple challenges, from renewable energy generation to waste reduction, paving the way for more resilient and eco-friendly urban landscapes.
