Scientists develop low-cost solution that generate electricity on air

Scientists at the University of Massachusetts Amherst have designed a device that can generate electricity from natural water vapor in the atmosphere. It can be a real game-changer when it comes to powering wireless electronics.

The device, invented by the "Air-genome", has been on the muddy banks of the Potomac River for more than three decades. There, scientists discovered an unusual microbe that is related to xenobacteria, which, among other things, produces magnetite without oxygen.

While experimenting with the material, electrical engineer Jun Yao discovered that - almost by accident - when nanowires interact with the electrodes in a certain way, they generate electricity.

"I have found that exposure to atmospheric humidity is necessary and the protein nanowire absorbs water, creating a voltage gradient across the device," the scientist said.

Current iterations produce a constant voltage of 0.5 volts, such as the ScienceArt Note, but many devices can be used to generate enough power to charge small electronics such as smartphones. Currently, the technology is renewable, pollution-free, low-cost, and operates even in desert lowlands. Unlike other renewable energy sources, such as solar or wind, it also works inside the home.credit: third party image reference

The team eventually wants to develop large-scale systems that can supply electricity from the grid. It is also possible to add wall paint to energize your home.
