Similar in concept to the Delphi fuel cell, the Vehicle Integrated Power Unit Regulator is designed to let troops charge their equipment without having to idle the engine.
But instead of using a fuel cell, the VIPUR has its own battery and alternator, and only turns the engine on when it needs charging.
The company said it's up to 75% more efficient than keeping the engine on all the time.
Minimizing the armed forces' dependence on oil saves soldiers' lives and is a lifeline like no other for the green energy industry.
