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?"

    1 m/s * 86400 seconds in a day = 86.4km. I don't think the battery is the problem, it's the pressures past 5k.
