Even in remote areas, you might need a charging port — if not for your phone, then maybe a camera, light, or radio. The Micro Wind Turbine can provide power in nearly any location using nothing but a breeze. It uses a vertical axis rotor to harvest energy, a telescoping design to making packing it more manageable, and an integrated battery pack to ensure it's making use of the available wind even if nothing's plugged in. Unlike solar panels, it even works at night. Sadly it's still just a proposal, albeit one with a working prototype.
