Robot patrols for ports?

July 30, 2014 - via BMT Group

These small, robust 1.8m torpedo-shaped AUVs connect with modems seated below the surface to link with the brains of the outfit onshore. Since the modems can be strung out on a chain across the port, handing over the data link from one to another, the AUVs can remain connected even when far from base, keeping up a harbour patrol day and night.

Pure lithium anode may treble battery capacity

July 29, 2014 - via Stanford University

The challenge of making a lithium anode is largely due to the reactivity of the pure metal and how such an anode would expand and contract on charging and discharging – cracking, degrading and forming dendrites. These factors would cause such batteries to be impractical, unstable, not long lasting. The Stanford scientists have overcome the above problems using a carbon nanosphere wall to coat the lithium anode. This 20nm thick "flexible, uniform and non-reactive film… protects the unstable lithium from the drawbacks that have made it such a challenge,

Judge dismisses lawsuit over Amelia Earhart search

July 26, 2014 - via Associated Press

"To be sure, there is dispute about what can be seen in the 2010 expedition footage and the source of any man-made objects identified. And whether Defendants found the wreckage in 2010 is disputed," Skavdahl wrote. "However, there is no evidence in the record that, in fact, the Earhart wreckage lies on the ocean floor off of Nikumaroro and defendants knew, or should have known, that fact upon review of footage from (the expedition.)"
