This Super-Tiny Windmill Could Someday Charge Your Phone

Researchers at the University of Texas at Arlington have come up with a way to build a nickel alloy windmill so small, 10 of them could be mounted on a grain of rice. And if all goes as planned, hundreds of the little things could end up in a case that charges up your smartphone.

UT Arlington's Smitha Rao and J.-C. Chiao designed the windmill, which at its broadest is just 1.8mm wide. Built from nickel alloy for rigidity, the little fan is self-assembled using wafer-scale semiconductor electroplating principles and a technique the team likens to origami. Rao and Chiao have partnered with WinMEMS Technologies Co., a Taiwanese company researching ways to build micro electro-mechanical systems, to bring the baby windmill to reality. More here.

I never thought of it that way.
