Phone batteries dying, spider webs of power cords — powering mobile technology can be pretty annoying for the average iPhone or iPad user. But it’s even more annoying — not to mention potentially dangerous — if you’re a soldier on patrol in Afghanistan losing juice on a critical gadget. Yes, troops in the field use their fair share of handheld gear, too. Now, the Pentagon is hoping to give them a power-up with a wireless charging system.
Darpa, the Defense Department’s advanced research shop, announced Wednesday that it’s looking to build a short-range wireless power transmission system for troops in the field. The transmitter would allow troops to charge up things like GPS without having to stop and plug in. If the system works, a single GI could strap on a battery pack and allow other troops to draw power from it wirelessly at a distance of up to two meters.
The push for wireless power is a problem born of an increasingly technology-equipped military. GIs in the field lug a lot of handheld electronic gadgetry — about five to ten pounds of just battery weight, according to Darpa. On top of that, the Defense Department keeps coming up with ideas for yet more portable electronic gear, from Android-based smart phones to universal translators. All that gear needs juice to keep going on long missions. If troops are out on patrol, they can’t just find a convenient socket to stop and plug in. Darpa’s hoping its wireless power system can prove a solution to energy needs in the field without adding a tangled mess of charger cords.
