Honey, I Shrunk The Windmills! To The Size Of An Ant
From KERA News Breakthroughs:
Commercial wind turbines stand more than a hundred feet tall, with blades nearly as long. The wind turbines developed by engineers at the University of Texas at Arlington are a bit smaller… just half than the size of an ant.
In a cold lab room at UT Arlington electrical engineering professor J.C. Chiao shows off a windmill. It’s mounted on a grain of white rice. The micro windmill is a tiny speck of metal with a rectangular base and three shiny blades the size of ant antenna.
“Just think about it this way,” Chiao says, “My interest and research focus is to shrink things.”
