"Various types of DC dry cell primary batteries constitute the state-of-the-art power supply for dismounted warfighters. Primary batteries provide stored energy but are often discarded when only partially used. This precaution prevents soldiers from starting a life-endangering mission with half-charged batteries. New warfighter electronic equipment provides better capability, but also requires additional energy storage. DoD estimates that future warfighters will carry approximately 9 kilograms (almost 20 lbs) of batteries to complete a 96 hour mission.

"Continuously, DoD has funded the development of individual energy components. Hybrid energy components for specialized applications are now in development. Optimizing the integration and management of these power generating, storage and distribution components is the final stage in obtaining a lighter weight system to meet future energy and power needs.

Overview

"This prize program encourages innovation from a broad range of individuals, teams, and institutions to provide technical solutions for the individual energy needs of warfighters in the field. The prize objective is a wearable power system that lasts four days and cuts in half the weight of the batteries carried. Competitors will demonstrate flexible power systems that the Department of Defense can tailor to its specific needs after the competition. Winning solutions may have commercial application in the fields of camping, hiking, and other extended outdoor activities.

Goal

"Demonstrate a wearable electric power system providing 96 hours of equipment operation at less than half the current weight. The power system should attach to a garment (vest) and provide 20W average electric power for 96 hours with peak power requirements of up to 200W for short periods. All components, including the generation, storage, electronics, and connections must weigh 4kg or less, including the attachment system. The total minimum energy required is 1920 W-hr (20W * 96hr).

Prizes

"The prize awards are 1st place - $1,000,000.00 USD, 2nd place - $500,000.00 USD, and 3rd place - $250,000.00 USD for a total of $1.75M in prizes for systems meeting or exceeding the performance criteria.
