The United States Marines are already using solar panels to reduce their reliance on fuel generators, but by 2025, the few and proud hope eliminate the diesel-chugging monstrosities entirely. The Office of Naval Research has announced new partnerships with Raytheon, Battelle and Emcore to develop a transportable hybrid system that would leverage solar energy, heat and biofuel to power a Marine outpost for up to 15 days. Not only would these systems run much quieter, but they'd also reduce the need for fuel supply convoys, which are prime targets for attack in battle settings.

Currently, researchers are tossing around ideas such as combining a Stirling engine with a satellite-shaped solar concentrator. As is, however, solar concentrators are considered too large for effective transportation. These efforts will take place under Renewable Sustainable Expeditionary Power program, which will keep yearly tabs on the progress of partner companies. To learn more, you'll find an overview video and press release after the break.
