According to reports, the widest part of this micro-windmill is only 1.8 millimeters. Although it looks delicate and fragile, it is actually made of a nickel alloy, which gives it a certain degree of flexibility, ensuring it will not easily "break" even when facing strong winds.
Such micro-windmills can be installed in large quantities on mobile phone cases. When a phone runs out of power, one simply needs to put on the case and place the phone by a windy window or wave it gently in the air; within a few minutes, the phone can be "revived."
The University of Texas stated that the manufacturing cost of these micro-windmills is low. In addition to charging mobile phones, people can create tablet computers equipped with micro-windmills or embed them into building walls to generate electricity for lighting, security, environmental monitoring, and wireless communication.
