Scientists have harvested clean energy from air, using the ‘Air-gen effect’

They say any material can be used to generate electricity this way as long as it’s dotted with tiny holes, 1,000 times narrower than a human hair. The discovery was made by researchers at the University of Massachusetts. The ‘Air-gen effect’ relies on humidity. Air contains tiny droplets of water, each carrying an electrical charge, as these droplets pass through tiny holes in material, they bump against it. This creates a difference in charge between the upper and lower sides of the material, turning it into a battery. It’s the same effect that creates lightning in clouds. #battery #electricity #science #cleanenergy #air
