Alternative Power Sources

This program will develop a series of lightweight highly-reliable power sources (5, 10, and 25Wh/day capacities) for installation by SOF at remote sensor sites. Front Edge Technology's (FET's) proposed approach is to integrate ultra-high-reliability solar cells and FET's new long-life solid-state energy-storage-device into a robust lightweight "Power Module". The module components will be similar to those now being used by FET to develop a man-wearable solar-power system for Marine expeditionary forces. FET's preliminary design of a 10Wh/day Power Module measures only 5" x 7", weighs approximately half a pound, and is expected to have 4-year reliability of 99+%. Phase I of the proposed program will produce a breadboard, design studies, simulated life testing, and three optimized designs. Full-size fully-operational 25Wh/day prototypes will be fabricated and tested during Phase II.
