Leah, this is going to be very popular because people are always wanting to charge their phone, and this would allow you to do it using the power of the weather, whatever the weather! I think the fact that you can charge up your phone using the power of the rain, the wind or the sun is absolutely amazing! It must be a very complicated device in order to allow it to use all those different types of energy. I like your drawing, too, especially the bright pink colour, you would never lose it! Great work, Leah, keep on inventing!
