Agreed, like all the rest of the bacteria, insect and animal kingdoms, Homo Saps will keep eating and growing exponentially until they consume everything in their path.  Like ecoli in a Petri dish, locusts every 7 years or the reindeer on St. Matthews island.

Another Sail design for shipping, on a cargo vessel.  14% reduction in emissions which is better than nothing, but in the photo there are no containers on the deck.  On a fully loaded ship, the containers would block the wing halfway up the vertical wings.  Plus, you're losing about 25-30% of the deck space to stack containers.  Not convinced yet with this solution.
