MICRO-WINDMILLS Power Portable Devices

摘要

Giant windmills now command the landscape in the quest for renewable energy resources. Researchers at the University of Texas Arlington, however, are taking the technology behind these titan turbines and shrinking it to power portable electronics. Measuring 1.8 mm at their widest point, hundreds of these micro-windmills could be embedded in a sleeve for a cell phone (see the figure).
