Using a device peppered with minute pores, researchers have found a way to harvest the electricity of water molecules in the air.
Researchers at the University of Massachusetts Amherst have found a way to generate electricity by harvesting moisture in the air., electricity can be harvested from air using a device made of nearly any material, merely requiring the material to be dotted with nanopores less than 100 nanometers —0.000004 inches—in diameter."We are opening up a wide door for harvesting clean electricity from thin air.
These pores are the same size as the length of the"mean free path" between water molecules, which is the distance traveled by the molecules in the air before they bump into another water molecule. This means that the upper part of the Air-gen would be bombarded with lots more charge-carrying water molecules than the lower part, creating a charge imbalance as in a cloud, which is the fundamental principle of generating a flow of electrical charge,"The air contains an enormous amount of electricity," Jun Yao said in the statement. Yao is an assistant professor of electrical and computer engineering at the College of Engineering at UMass Amherst and the paper's co-author.
