On February 17, 2020, researchers from the University of Massachusetts Amherst (UMass Amherst) announced that one of its laboratories has developed a device using a natural protein to create electricity from moisture in the air. Electrical engineer Jun Yao and microbiologist Derek Lovley have created what they call “Air-Gen,” which consists of an air-powered generator with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the atmosphere. According to Yao, the device generates clean energy 24/7. What Yao and Lovley describe as a low cost, non-polluting, and renewable device, can generate energy even in areas with extremely low humidity, such as the Sahara Desert. Although the current generation of Air-gen devices are only able to power small electronics, both scientists state that the ultimate goal is to develop large-scale systems that will highly contribute to sustainable energy production.
