We've seen a couple interesting attempts to convert vibrations and sound into electricity, but the latest design from a team at the University of Southampton is the first we've come across that's designed to be attached to bridges, large buildings, and other structures. The sugar cube-sized generator, a smaller version of a design already commercially available, uses cantilever-mounted magnets to induce a current in a copper coil -- a use of magnets to generate electricity that doesn't violate any laws of thermodynamics, which is always appreciated. The team has successfully used the generator to power an accelerometer (pictured), and tests indicate that the unit can put out up to 46 microwatts of power -- enough to run a pacemaker off the vibrations of the heart itself. No word on commercial availability, but the team seems like they're ready to get shaking fairly soon.

We've seen mechanical devices creep through the inside of intestines, huge mounds of dirt, and even through the San Francisco Bay, but now a British deep-diving remotely operated vehicle (ROV) is getting set to probe the depths of Antarctica. In hopes of uncovering more about the effects of glaciers on the ocean floor, as well as details about the living creatures that inhabit said areas, UK scientists are carting the machine aboard the RSS James Clark Ross as they head for the Marguerite Bay area on the west side of the Antarctic Peninsula. The robot, dubbed Isis, will spend time on its inaugural January mission combing the seabed and channeling live video and pictures back to its captains via the built-in cameras, lights, sonars for acoustic navigation / imaging, and two remotely-controlled manipulator arms. Once the bot gets dried off (and thawed out) from its arctic expedition, the next tour of duty is already lined up, as Isis will head off to the Portuguese coast to do a bit more sightseeing. Of course, if you're interested in taking the £4.5 million ($8.81 million) creature out for a mission you deem worthwhile, it should be available for deep-pocketed renters soon after.

We're not sure if we like the idea of our car watching us as we drive, but we'll all in favor of any tech that'll make us safer. This past week at the Intelligent Transportation Systems exhibition in London, a new set of cameras mounted on the dashboard in a prototype vehicle will make sure that a driver's attention is focused on the road. According to MotorAuthority, the new cameras will be trained on the driver's eyes and will flash a warning light and will sound an alarm if it finds that the driver's eyes aren't staring at the right places at the right times. Furthermore, as New Scientist reports, these new sensors -- developed by researchers at University of Southampton in the UK-- are also able to determine what other cars and objects around the car are doing, all of which could lead to safer road design and a more thorough understanding of driving behavior.
