Who knew foot soldiers hauled around so many batteries? The average GI carries 18 pounds of the little power cells every day, which is just two pounds shy of how much protective gear they\u2019re wearing. But if the batteries became <\/i>the protective gear, that would be a literal weight off soldiers\u2019 backs. Gabriel Veith at the Oak Ridge National Laboratory is looking into how to make protective batteries for men and women in fatigues, according to New Scientist<\/i><\/a>.<\/p>\n

His prototypes so far are just normal battery packs, but with a little silica injected into them. The additional nanoparticles don\u2019t impact the battery\u2019s fluid electrolytes until the battery is mechanically shocked \u2014 you know, the kind of disturbance a bullet might make. On impact, the silica and electrolytes become solid, which should stop the bullet from going any farther.<\/p>\n

Veith and his research team have proven this works in small batteries, but have yet to scale up to ones that would cover a fair amount of skin. Soldiers already wear batteries of this size now, but they can be a safety hazard. If struck with a bullet in the wrong place, the batteries can leak or explode.<\/p>\n

In fact, if these durable batteries were available, it would almost guarantee that they wouldn\u2019t get thrown out (the military specifically asked<\/a> that they also be rechargeable). And the less toxic waste the military leaves behind, the better. The government branch is one of the nation\u2019s largest polluters. Even worse, they often outsource clean-up to contractors without much oversight, meaning sites are often not cleaned to standards or cleaned up at all, as ProPublica<\/em> reports<\/a>. What waste military does handle themselves is often burned<\/a>.<\/p>\n

The Department of Defense recognizes<\/a> that climate change is a problem, and that it might also start to impact what the job entails \u2013 like navigating food shortages. Perhaps the push for reusable, durable batteries shows they\u2019re also hoping to cut down on the way they\u2019ve advanced climate change, too.<\/p>\n
