If Pentagon planners have their way, the military could soon become a lot quieter and more fuel-efficient: They are pushing to add anti-idling technology to their next-generation workhorse vehicle, the partial replacement for the Humvee.
“The warfighter purpose and the view of climate as a national security challenge are fully aligned in cases like this,” Deputy Defense Secretary Kathleen Hicks said after a tour in the Pentagon courtyard of an exhibition of climate-friendly technology, including prototypes of vehicles with anti-idling technology.
The anti-idling system is not complicated. The vehicle gets extra lithium-ion batteries, just a little bigger than those used in regular cars. And it gets some extra equipment to automatically flip the engine back on whenever the spare power needs an extra boost. That means the vehicle briefly rumbles back to life every few minutes. In the meantime, soldiers can use their radios and other communication devices, along with air conditioning or heating, without idling the engine nonstop.
“If you look at each vehicle, maybe that’s not a lot of fuel, but when you look across the deployed force, that can be really significant,” said Joe Bryan, the chief sustainability officer of the Defense Department.
