Описание к видео Our Inventions.flv

We've made Wind Turbines which can be used in our homes to generate electricity from the wind of an electric ceiling fan.
The electricity generated can be used to charge our cell phones , I-pods and other small devices!
Such devices will be very useful in the near future as they can help us save energy.
