CNN reported a contest from the US Military to design a powered suit / load reducer to lighten the weight that infantrymen carry:
i can think of a bunch of different interpretations for this one
edit - the cnn link is down but the general concept was as follows:
the increasing amount of technical gear carried by each individual soldier demands the development of a system that can either: A)provide large amounts of electrical energy while remaning lightweight (to replace the 50 pounds of batteries currently carried by troopers) or B)synthetically enhance the load bearing abilities of the wearer... some sort of exoskeletal musculature that enhances the user's abilities.
ambition makes you look pretty ugly
