kc123 writes in with news that Rolls Royce is designing unmanned cargo ships
."Rolls-Royce's Blue Ocean development team has set up a virtual-reality prototype at its office in Alesund, Norway, that simulates 360-degree views from a vessel's bridge. Eventually, the London-based manufacturer of engines and turbines says, captains on dry land will use similar control centers to command hundreds of crewless ships. Drone ships would be safer, cheaper and less polluting for the $375 billion shipping industry that carries 90 percent of world trade, Rolls-Royce says."
