Scientists at the University of Massachusetts Amherst have invented a new way to make electricity. Their method uses super-tiny holes to make electricity from moisture (湿气) in the air. The scientists hope the method will one day lead to cheap clean electricity anywhere at any time.

Moisture in the air is what helps create electricity. Water droplets in the air carry an electric charge (电荷). In clouds, these water droplets build up large charges, which we later see as lightning. One of the researchers, Jun Yao, described the new invention as a "small-scale, man-made cloud". Since the new device generates electricity from the air, the scientists call it "Air-gen".

Currently, the device only makes a small amount of electricity- enough to power a small sensor. But in lab tests, the Air gen, which is a little bigger than a fingernail, produced electricity all day and all night for a week, powered by nothing but the air.

The scientists have tried to make electricity from humidity before, but those methods didn't work for long, or were expensive to make. But in 2020, Dr Yao and his team found a way of getting electricity from humidity using special "nanowires" made from bacteria. That research led the scientists to the key discovery of the Air-gen: almost any material can create electricity in this way as long as it has nanopores (纳米孔) of the right size. This is important because it means in the future, the devices can be made very cheaply. The researchers hope that the Air-gen will become an important green energy source.

Many scientists are impressed with the ideas behind the Air-gen. But some scientists have suggested that it might be hard for the Air-gen to create enough electricity to really make a difference especially compared to power sources like solar energy. But Dr Yao and his team are working on ways to make the Air-gen technology more powerful. Because the device is s0 thin, the scientists believe that many Air-gen layers could be piled on top of each other to create more electricity without taking up more space.
