A couple of researchers at the University of Texas Arlington have come up with an even cool concept that you might use in the future to help charge your devices, and that is through the use of minuscule windmills that are apparently so tiny that you could fit about 10 of them on a grain of rice itself, meaning that it is also small enough where you could embed it into a phone, hold it up to a fan or just walk with it that it could potentially juice up your device.
Portable solar chargers aren’t so out of the ordinary anymore, but minuscule windmills that can charge your phones? Now, those are something new. A couple of UT Arlington researchers, Smitha Rao and J.C. Chiao, have developed wind turbines so small (they measure 1.8mm at their widest), you can stick 10 of them on a grain of rice. One possible application is to embed a bunch of the Lilliputian devices onto a phone sleeve — you can then simply hold your phone out the window or place it in front of a fan to recharge.
