When we talk about wind power, usually we refer to those gigantic, tall, wind turbines that are few stories in height, with blade-span of few ten of meters. Soon this will not be the case.
Skajaquoda, a research team based in Minnesota, U.S.A., has come out with a portable wind turbine, called Trinity, that will charge any USB device like your smart phone or tablet and folds together into a 12" cylinder. It measured about 23" when operating and weighted about 1.8 kg. Below shows the device.
Trinity has a 15W generator and a built in 15,000 mAh battery. When it is folded, you can view it as a 12" long cylindrical battery bank. You can either charge the battery using the build-in wind turbine or with a 5V USB wall-plug.
Skajaquoda has turned to Kickstarter to raise US$50,000 to complete the prototype and start the manufacturing process. At US$249 you will receive the first of the Trinity devices and be expected to receive it by January 2015.
