Tiny Autonomous Submersible

Posted by michael on from the capsela dept.

dAzED1 writes "The BBC is reporting that Australian researchers have built a 40cm, self-controlling submarine that can dive to 5,000 meters. It's small enough that there is concern it could simply be eaten, or worse, used by the military. My question is, at 1 m/s, how does it get to 5km before the 1-day battery dies?"

    How much battery power do you think it takes to sink into the ocean?

    Why "or worse"? Giving our military better technology is often times the best way to avoid becoming entangled in lengthy conflicts and reliance on poor intelligence.

    I imagine that one day there will be thousands of these robots constantly monitoring the ocean's vitals...
    I imagine them being rechargable on their own, too. What if they were covered with solar panels and when the battery went dead it would float to the top and recharge on sunlight...
