Context: Researchers are exploring the concept of hygroelectricity, which involves harvesting electricity from humid air.
Methods of generating hygroelectricity:
- Using tiny protein nanowires produced by bacteria to trap water molecules and create electrical charges, potentially providing usable electricity to power miniature computers or sensors.
- Another method involves passing humid air between two pieces of metal, inducing a charge as the moist air flows over them.
Advantages: Versatility, sustainable.
Disadvantages: Scale up of technology.
