Scientists at the University of Massachusetts Amherst have developed a device that creates electricity from the moisture in the air. Electrical engineer Jun Yao and microbiologist Derek Lovley’s device which they call “Air-gen” uses electrically conductive protein nanowires produced by the microbe Geobacter. When water vapor naturally present in the atmosphere comes in contact with these nanowires, current is generated.
This new technology is renewable, low-cost, and can generate electricity 24/7. It’s even able to generate power in extremely low humidity areas such as the Sahara Desert.
According to the scientists, the current version of Air-gen devices can power small devices such as cellphones. The commercial version is coming soon.
