Scientists at the University of Texas Arlington have developed tiny windmills which measure only 1.8mm in width, which means you could put 10 of them on a single grain of rice. According to researcher J.C. Chiao, if you were to stick a hundred of them to a smartphone case and hold it in the wind, it would charge your smartphone in just a few minutes.
Built using flexible components, the windmills are bizarrely tough for something so small and can stand up to strong winds without fracturing.
"These inventions are essential to build micro-robots that can be used as surgical tools, sensing machines to explore disaster zones or manufacturing tools to assemble micro-machines. Flat panels with thousand of windmills could be made and mounted on the walls of houses or building to harvest energy for lighting, security or environmental sensing and wireless communication."
