Energy Innovations: Nanowire Natural Electricity
It sounds like science fiction but it is true: a continuous flow of electricity can be generated out of thin air, using the moisture that is naturally in air everywhere in the world - even in deserts.
Researchers at the University of Massachusetts in Amherst discovered years ago that certain microbes that live in muddy water have filiments that conduct electricity. Now they’ve made a thin film of these ‘protein nanowires.’ NATURE published the paper detailing the new use of nanowires in February 2020. The researchers wrote:
Here we show that thin-film devices made from nanometre-scale protein wires harvested from the microbe Geobacter sulfurreducens can generate continuous electric power in the ambient environment…We find the driving force behind this energy generation to be a self-maintained moisture gradient that forms within the film when the film is exposed to the humidity that is naturally present in air.
