Australian Army Invests in Electrical Shirts

Posted by samzenpus on Thu Nov 01, 2007 03:57 AM
from the shocking-sleeves dept.
The Military Power Technology
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."

        Just curious .. if the vibration energy is derived from a battery powered device, does this mean that our female soldiers on solo assignments can safely assume they will never run out of batteries?

          Indeed, why stop there? They should spend another 4 million and develop the Nude Bomb and shower the enemy skies with toys. Then it's just a matter of waiting before the enemy nation becomes a tourist haven for obese elderly nudists. Even the thought of that would be enough to cause widespread peace, I'd have thought.

    The first law of thermodynamics states: "The increase in the internal energy of a system is equal to the amount of energy added by heating the system, minus the amount lost as a result of the work done by the system on its surroundings".

    This means that while it is perfectly possible in theory for soldiers to charge batteries by running around, they will have to exert that extra energy themselves. I doubt that any soldiers (already heavily laden with weapons, body-armour and other gear) will want to wear suit that requires more energy from you for movements than normal suits.

      True, but I guess those shirt will harvest energy from body heat the soldiers would have lost anyway and from movements the soldiers would have done anyway. This way, the shirt would only be recycling energy which would've been otherwise lost.

      On the other hand, imagine if the battery somehow breaks starting to leak acid all over the guy's skin.

          that's not what he said. Let me translate:

          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.

      Whats this really matter its still a plus for the soldiers system must do the work regardless and the expended energy is going into a system which has a positive effect on the soldier as it is lighter then previous disposable solution?

    • The laws of thermodynamics hold perfectly true, but it's not a simple closed system. This system sounds as if it is harvesting waste energy. (the running that the soldier is already doing) The extra effort exists in the weight of the unit, but since it replaces another, chemical battery system, the tradeoff will likely be negligible.

        The running is not waste energy - the energy used for running is spent up doing just that - running. Granted, the muscles will produce heat, which can be used - but the article seems to suggest that it is not heat which will charge the batteries, but rather the actual motion.
    • They will already be doing work to bend and flex their existing suits, it's just being lost as there is no mechanism to catch it
    • It all depends on whether the extra force is more than carrying batteries around or not.
    • The main thrust of the technology is to both distribute the battery weight around and harvest some energy to charge them, looks like possibly up and down movement of a walking/running person. since they have to lift the battery anyway (stated as weighing several kilos in the article) as long as the charging mechanism does not weigh too much it would be quite useful. just off the top of my head the cells up and down movement in the jacket could pull directly on a cable hooked up to a geared flywheel to driv

    • That isn't actually as insane an idea as it may sound. In climates where the outdoor temperature is lower than the body temperature you could theoretically convert a fraction of the thermal energy that flows out of the body into electricity. Of course, the second law of thermodynamics limit the efficiency of the conversion, so you wouldn't get a whole lot of energy out of it unless it was REALLY cold outside, so a battery or flexible solar cells in the fabric would probably be preferable.

    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.

      Having spent some time in the field wearing various uniforms, I have to say, the idea of wearing a bunch of plastic and metal fibers in the field doesn't sound very appealing. It sounds like a recipe for heat exhaustion.

      Are other energy sources really so inconvenient that this is justifiable?
