Generating electricity from the moisture in the air with the help of bacteria
So what is the basic idea? Growing favorable nanofilms from bacteria that can draw small amounts of electricity from water vapor in the air. “Air contains an enormous amount of electricity. Imagine a cloud that is nothing but a mass of water droplets. Each of these droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt, but how can we reliably generate electricity from a lightning bolt?” said electrical engineer Jun Yao. “What we’re doing is building a man-made, small-scale cloud that generates electricity for us predictably and continuously so we can harvest it.” said.
Can be used on most materials
Because of its bacterial basis, the material’s initial discovery in 2020 was heralded as an intriguing new avenue for green energy technology. Yao and his team continued to explore the concept and say they found the concept to be more generalizable than previously thought.
As long as the nanofilm has tiny holes, the material seems unimportant, the team said. While the team is currently mostly focused on generating tiny amounts of electricity for wearables, it’s already opening up interesting new possibilities for consumer technology.
