Resumen de Wind whips plastic grass to produce power
The wind flowing over one's roof is packed with energy, if he could only harness it. A new type of wind power generator can do just that, by carpeting a surface with plastic strips that sway in the wind like grass. It produces renewable energy where traditional windmills would be impractical. The generator is made by fixing flexible strips of plastic to aboard, so they stand upright like rows of dominoes. The strips have nanowires etched on one side and a coating of indium tin oxide (ITO) on the other. When the strips flail in the wind, the nanowires slap against the ITO surface of neighboring strips. This temporary contact allows electrons to leap from one material to the other, creating a current through a phenomenon known as the triboelectric effect
