For decades, "bigger is better" has been the conventional path to efficiency in industries ranging from transportation to power generation. Food once grown on small family plots now comes overwhelmingly from factory farms. Vessels that carried 2,000 tons of cargo have been replaced by modern container ships that routinely move 150,000 tons. But now, new research shows, we are on the cusp of a radical shift from building big to building small -- a change that has profound implications for both established and emerging industries.
