With large cargo freighters being a major source of CO2 emissions
worldwide it's been encouraging to see various efforts to make such vessels more efficient. In recent years we've seen the development of the world's biggest container ship
to cut CO2 emissions per container moved, air bubbles
used to cut the friction between a ship's hull and the ocean, and even plans to return to the use of sails
to cut fuel use. Now Nissan has launched an energy efficient coastal car carrier called the Nichio Maru that employs solar panels, LED lighting, a low friction hull coating hull and an electronically controlled diesel engine to cut fuel consumption.
