The document outlines a technology challenge focused on developing small, lightweight, modular power generation solutions for unmanned systems, with funding up to £750,000 across two phases. It specifies requirements such as a 700 wh/kg output for around 48 hours, and clearly distinguishes between acceptable proposals and those that are not desired, such as purely battery-based ideas or marginal improvements. The timeline for project completion is set for December 2017, with a competition closing date of February 1, 2017.
