The material can be applied like paint to the hull of a ship and can move in response to an electric current to dislodge bacteria and prevent accumulations on the ship’s surface. Bacterial buildup on ships increases drag and reduces the fuel economy of the vessel, as well as blocking or clogging undersea sensors.

Prospecting For Wind And Sun On The OBX

Dominion North Carolina Power plans to study the prospect of wind and solar energy on the Outer Banks for small-scale power grids.  The utility is launching a three-year research project at its office in Kitty Hawk. The plans include four wind turbines, solar panels and a storage battery that will work to reduce the amount of power the office pulls from the grid.  Project manager Sarah Cosby says that network creates a so-called micro-grid that could be useful for small communities during power outages.

Study Finds Toxic Flame Retardant In Many Sofas

Your favorite couch or sofa could be dangerous for your health. More than half of all couches tested in a Duke University-led study were found to contain potentially toxic flame retardants. One of the main offenders: a chemical called "Chorlinated Tris". It's a probable carcinogen that was used in children's pajamas back in the 70's. It was phased out due to its health risks.
