The Military Power Technology

Australian Army Invests in Electrical Shirts 124

Stony Stevenson writes "The Australian Defence Department has injected $4.4 million worth of funding to further Australia's national science agency's (the CSIRO) research into designing clothing which can be used as a self-recharging electrical source on the battlefield. The Defence Department is hoping the technology can be used to replace cumbersome disposable batteries that soldiers must carry on the battlefield. The Flexible Integrated Energy Device (FIED) will be used to store and provide energy over a continuous period of time. It can be charged by either vibration energy harvesting or through plugging into an electrical power point."

          Current method is inefficient. New method is also inefficient, but not as bad as first method. Thus, even though the total system energy will be depleted eventually, less is being wasted rather than being converted to useful work in the new method. SO IFF the new method is 'less bad', the overall system will see an improvement in function. No perpetual motion required. The guy still has to 'plug in' at some point.

    The extra weight of the clothing is offset by not having to carry the extra batteries. So it shouldn't place anymore weight on the troop. I know it's much more convenient for me to wear a loaded photographers vest than it is to carry the bag. Same weight, but the distribution of that weight on your shoulders feels much better at the end of the day.

    My concerns are these.

    What's this vest made of? If a trooper takes a bullet through the vest, what type of stuff from the vest is going to follow the bullet into the body?

    If this shirt is meant to be worn under armor then what impact does the constraint of being sandwiched between the body and the armor have on the overall effectiveness of the shirt?

    If the shirt is meant to be worn over the armor, is there any redundancy to the power generation when the shirt takes a hit? With batteries, the trooper could always ask a buddy for a spare battery. Asking for the shirt from your buddies back, in combat, would probably be looked on negatively.

  • If you do just a teensy bit of the math, the idea of recharging by "vibration" or body motion is revealerd to be quite ridiculous.

    First let's estimate how much of your body motion you would not mind having drained off. Let's say you're walking, that takes about 0.05 horsepower. Let's assume you would not mind having some VERY STIFF pants that siphon off 10% of your walking power. That's 0.005 of a horsepower.

    Then let's assume that the motion sensors are 20% efficient, which is rather high for your typ
