Objective Summary
Develop a modular, self-sustaining, non-toxic subsea energy-harvesting capability that exploits naturally occurring sediment-seawater geochemical gradients to provide persistent, logistics-free power for distributed Intelligence, Surveillance, and Reconnaissance (ISR) sensor nodes in Arctic marine environments, with reliable operation at -2°C, and providing at least 250mW average net harvested power and storing sufficient energy in an onboard storage subsystem to operate up to a 5W (objective) sensor payload for 10 minutes every 4 hours over a projected 24+ month deployment.
The full objective, description, Phase I, II and III requirements and evaluation criteria are in the official topic on DSIP.
