I am going to be honest with you; I have seen many ideas and concepts that look at harnessing solar power, but none as creative as the eSaving. Here is a device with a retractable solar sheet and ability to charge devices using a USB base. It features 2 regular USB connections and 1 for the USB 2. Love the clean and simple approach towards problem solving.
