Researchers say device can generate sustainable power from gentle breeze
Scientists have developed a “tiny wind turbine” that can scavenge energy from the breeze made while walking.
Imagine rubbing a balloon on your hair for a few seconds – can you hear the crackle of static electricity, see your hair stand on end? That energy, powered by the contact and separation of two materials, can be bottled up and stored for use, according to researchers working on the device.
