M12, Microsoft venture arm, has announced a $11 million Series A funding round for Nautilus Labs, a New York startup that uses artificial intelligence (AI) for fuel efficiency on ships. The goal is to use collected data on weather patterns and vessel speed to influence decision making on fuel use. Nautilus plans to use AI to deliver real-time analytics and alerts to ship crews that could help save more than 10 percent on emissions in a single voyage. California’s NVIDIA Corp. is working with another AI startup in San Francisco. Japan’s Hitachi Ltd. is pursuing similar technology in Europe.
