If you have ever needed to use your cell phone on a camping expedition and realized that your battery has gone flat, you understand the frustration.
This new invention is wind powered. The wind causes the windmill to rotate which in turn transfers energy to a battery box, which can be used to charge you cellphone. Weighing only 150 grams, the windmill can be situated on top of your tent, as it charges your phone.
The energy created can reach half a watt, which equates to a 1-2 hour full charge length of time.
Solar powered equivalent can perform just as successfully, but often the sun is shielded, making this a useful alternative.
