A UT Arlington research associate and electrical engineering professor have designed a micro-windmill that generates wind energy and may become an innovative solution to cell phone batteries constantly in need of recharging and home energy generation where large windmills are not preferred.
Smitha Rao and J.-C. Chiao designed and built the device that is about 1.8 mm at its widest point. A single grain of rice could hold about 10 of these tiny windmills. Hundreds of the windmills could be embedded in a sleeve for a cell phone. Wind, created by waving the cell phone in air or holding it up to an open window on a windy day, would generate the electricity that could be collected by the cell phone’s battery.

Wind turbines hovering high in the air and tethered to the ground, like kites, have the potential to generate huge amounts of electricity, based on a recent wind availability study led by the University of Delaware.
Researchers pinpointed tracts of the atmosphere ideal for locating airborne wind energy (AWE) devices, which convert kinetic energy from wind into electricity. Findings published in the April issue of Renewable Energy show that there are enough areas usable by airborne turbines to produce several terawatts of electric power annually — more than enough needed to meet worldwide demands.
