Sure, solar-paneled bags are occasionally practical and always geeky, but the women in our lives wouldn't dream of letting us walk around with one, let alone using one themselves. That soon may change. The Solar Handbag from Diffus, a Danish design studio, integrates 100 "solar sequins" in a pattern that ladies may actually find socially acceptable, perhaps even attractive. During the day, the bag is capable of generating 2 watts of power, enough to charge many portable gadgets. After the sun sets, however, any leftover energy is redirected to a set of optical fibers, which glow whenever you open the bag to search for mascara, ABC gum stuffed in crumbled receipts, or whatever else you've decided may never leave your side. There's no word on whether the bag will actually come to market, but if it does go to production, it may just end up being affordable, given that many handbag budgets far exceed the amount we set aside for gadgets.
