“The #UMass Amherst team were surprised to find that the device, which comprised an array of microscopic tubes, or #nanowires, was producing an electrical signal regardless.
Each nanowire was less than one-thousandth the diameter of a human hair, wide enough that an airborne water molecule could enter, but so narrow it would bump around inside the tube. Each bump, the team realised, lent the material a small #charge, and as the frequency of bumps increased, one end of the tube became differently charged from the other. ‘So it’s really like a battery,’”

"Unlike solar or wind, #hygroelectric generators could work day and night, indoors and out, and in many places."

‘It was an accident’: the scientists who have turned humid air into renewable power
The promise of #electricity from humid #air – #hygroelectricity – is capturing researchers’ imaginations.
In May, a team at the University of Massachusetts Amherst published a paper declaring they had successfully generated a small but continuous electric current from humidity in the air.
“To be frank, it was an #accident,” says the study’s lead author, Prof Jun Yao. “We were actually interested in making a simple sensor for humidity in the air. But for whatever reason, the student who was working on that #forgot to plug in the #power.”
