Designed to spur innovation, the competition was launched in July 2007 by the DoD’s Research and Engineering Directorate to help develop a long-endurance, lightweight power pack for warfighters in the field. After beginning with 169 registered entries, the ultimate testing concluded on Oct. 4 when the final six teams met at Marine Corps Air Ground Combat Center Twentynine Palms, Calif., to determine the winner.
DuPont/SFC won the competition by building the lightest wearable system that provided an average of 20 watts of power for more than 96 hours and weighed less than 4,000 grams, or 8.8 pounds. AMI of Ann Arbor, Mich., was awarded $500,000 for second place, and Jenny 600S of Middleburg, Va., won the $250,000 third place prize.
All of the finalists used either fuel-cell or battery technologies or a combination of both to meet the rigorous standards set by the DoD.
