The US Defense Department is looking to lighten the load soldiers have to lug around in order to keep all their gear powered, and its hoping the general public can help them do it. To that end, the DoD's gone and busted out a DARPA-style competition, with a million dollars in prize money in store for the winner. They'll have their work cut out for them though, as the competition demands that the power supply be half the weight of current systems while still providing the same amount of power (or more). That translates to a system that weighs no more than 4 kilograms (8.8 pounds) and provides enough power for 96 hours of operation, with a peak power requirement of 200W for short periods. Even if you don't come out on top, you'll still have a shot at the $500,000 and $250,000 prizes for second and third place, although you'll have to get your act together pretty quickly: the cut-off date for registration is in November of this year, with the whole thing set to wrap up a year after that.
