A $25 million autonomous ship will launch in 2018

A crewless ship to be christened the Yara Birkeland is expected to start sailing in 2018, initially delivering fertilizer along a 37-mile route in southern Norway.
The electric-powered ship will be miniscule by modern standards, with the capacity for 100 to 150 shipping containers. But its arrival could be a huge turning point for the global shipping industry.
The ship, according to the Wall Street Journal, will cost $25 million, about three times as much as a conventional ship of similar size,
