The answer that B9 is proposing is a coastal cargo ship that combines massive carbon-fibre DynaRig sails - such as those used on the superyacht, the Maltese Falcon - with an engine that runs on bio-gas made from food waste using a process called anaerobic digestion.
The ship drifted undetected until late last month when a Canadian coastal air patrol spotted it several hundred miles off the Queen Charlotte Islands, an archipelago on the north coast of British Columbia.
The DDG 1000 is a multimission surface ship designed to provide advanced land attack capability and contribute to military dominance in the shallow coastal waters known as the littorals.
