Australian Army Invests in Electrical Shirts

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."

Now say after me

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.

Hadn't thought about this possibility.

Yeah, right.

Yeah, but...

...if [the extra exertion required to charge this shirt] is less than or equal to [the energy needed to haul around those batteries the shirt will be replacing], then it's a net win. In fact, even if the shirt requires more exertion, it might still be worth it not to have to worry, "Do I have my batteries with me today?" "Are my batteries charged?"

That problem lessens itself if you've got both types of soldiers.
