It has been a while since I have been excited by a piece of luggage, and while this is still in prototype phase, I still want one. This gadget charging luggage, designed by Jung Inyoung, has a built-in battery which charges while the bag is rolled about. This internal battery can then be used to charge your electronic gadgets. There is even an LED indicator on top of the luggage which shows you how much power you have stored.
No more hunting for power outlets at the airport. Not sure how the TSA dorks will react when this goes through the x-ray machine though.
