recharge: american troops may become their own batteries - battery energy

If 120-
High temperature and 70 degrees in summer
The pound load is not enough, and the American forces in Iraq have been exhausted by a surprising source-their own batteries.
Three typical.
Daily deployment, soldiers carrying about 65 batteries
Weighing up to 30 pounds
Power their night.
Goggles, flashlights, GPS and other tools.
In addition to this, the weight of the body armor and the Kefla fiber is also very large.
Now, Lockheed Martin has begun to solve these two problems.
It plans to turn the soldier's body armor into a power supply that will charge the body armor and make the total weight insignificant.
Armor can also solve another power issue if it succeeds.
It is estimated that 40% to 50% of battery energy is wasted because the key components of the soldier kit do not have a sleep mode when they are inactive to save power.
This means that the normal battery is dead.
The power can be controlled and the standby mode can be adopted by Lockheed's bulletproof vest, which means that these key tools can last longer.
The study was sponsored by the Department of Defense's bureau of advanced research projects and passed preliminary tests.
Richard Edwards, vice president of tactical missile and combat maneuver systems at Lockheed, said the armor was safe and viable.
Preliminary data show that armor can be powered on when small armor is successfully stoppedarms fire.
With the race to solve the power puzzle, the people at Lockheed are not the only ones who see the future of charging technology.
Scientists at Georgia Tech have created a wearable power supply that they call a "power shirt," a device with a nano-line that can take advantage of the movement of the body, even to the blood flow under the skin.
The tiny wires are attached to the fibers in the shirt and use the body movements of the soldiers to combine the current of many pairs of fibers woven together.
It can generate enough power to power a range of small electronic devices.
It's not just a shirt that can be a power source;
By weaving the fibers into other materials, the kaifla fiber jacket and even the tent can use this technology to draw energy from sound vibration or wind movement.
Still, the moisture in the sweat
Or worse, the washing machine.
May cause problems with zinc in shirtsoxide wires.
But the shirt is enough for now because some soldiers would rather stink than break their backs because of the battery.
This fall, the Defense Department will sponsor a $1 million prize for developing wearable power systems weighing less than 4 kilograms (8. 8 pounds)
And power four people. day mission.
If one of the 100 teams competing for the award is successful, if these technologies take off, the US military will soon bear a lighter burden.
