#6: Improve operational energy
Subtopic Title: Solar Powered Systems
Description: US Army has an interest in any Technologies / Processes / Logistics / Products and Procedures for Solar Powered systems to include but not limited to Refrigerated Container. For refrigerated containers, demonstrate the capability for reducing operational energy for refrigeration units serving 20-foot containerized cold storage assets through the use of advance compressor, heat-exchanger, expansion valve, and control technologies. The objective is to reduce the amount of fuel used by refrigerated containers by 30% annually and 50% during the hot season, reduce the procurement cost of the refrigeration unit, dramatically enhancing reliability, and providing enhanced operational capability, especially in hot climates.
Subtopic Title: Waste/Wastewater Remediation and Environmental Control
Description: US Army has an interest in any Technologies / Processes / Logistics / Products and Procedures for small-scale onsite waste remediation and energy recovery - Expeditionary wastewater Treatment - Improved Environmental Control. The target scale is small and/or extra small expeditionary bases with an estimated waste generation rate of up to 1 ton/day of mixed waste. The objectives are to reduce the solid waste mass and volume by 90% or more, require minimal manpower, improve operational efficiency and produce only benign residues and emissions. Hardware to be packaged for rapid deployment (e.g., 6.5'x8'x 8' triple container), and
be self-powered or better in terms of JP-8 fuel and electric power. For wastewater treatment, fabricate prototype and validate the capability for improved operational energy for efficient, novel, and non-biological expeditionary wastewater treatment technology enabling reuse of greywater or the treatment of black water for safe on-site disposal. For improved environmental control, potential examples include rapidly deployable floor-based heating systems and higher efficiency air conditioning technologies that outperform existing electrical environmental control units. The overall objective is a 10% to 30% improvement in operational efficiency will justify the return on investment. Improving comfort levels of War fighters deployed in austere environments will significantly improve operational readiness and effectiveness.
