This one is for those ladies with iPods. We know you shove enough crap in your purse already, so why bother cramming a charger in there when you know it still won't fit? The solution is the Power Purse. This design concept is a purse with individual solar panels on the outside and a USB charger on the inside for powering all those gadgets you have stuffed away in there. Developed by college kiddo Joe Hynek, the purse is not only designed to power devices, but also to clock in at under $300, so it's semi-affordable.
