If you are looking for alternative means to charge batteries while backpacking, camping, or otherwise experiencing the outdoors, you may consider the Micro Wind Turbine. Created by Nils Ferber, it is a light-weight and foldable wind turbine that you can bring in a backpack, to help you take it to the seaside, the game reserve, or perhaps the local backcountry. Simply secure it to the terrain on a windy spot and connect it to whatever you’re recharging, whether it’s a mobile phone, a digital camera, or a handy battery unit.
Unlike traditional wind mills, the Micro Wind Turbine makes use of a vertical axis rotor that revolves around a couple of mini-sails. As the wind blows on the sails, they propel the rotor spinning to produce energy, with the sails in a position to capture the wind, no matter which path it will go. It has an inbuilt battery pack where any particular power produced is instantly stored, along with a USB port for connecting your mobile devices.
