Concerned about the effect of copper and other heavy metals on ocean life?
Gone are the days of wooden ships and iron men and heaving the trash overboard to lie in the wake of the underway ship.
University of Pittsburgh PH.D’s are developing a non toxic coating to be applied to ships to replace copper to stop barnacle growth on ships.
Now if they simply combine it with sound absorbing technology perhaps we will have a stealth aircraft carrier to rule the seas with in the near future.
Go Navy! Saving marine life around the world while keeping the sea lanes safe for travel!
