Cape Cod, Mass., is deeply rooted in tradition and its maritime past. Historic church steeples fill the skyline, 300-year-old sea captains’ homes dot the landscape, and sailboats grace the oceanic horizons.  So when an energy entrepreneur proposed building a massive ocean-based wind-energy project in nearby waters, locals were understandably shocked. Although similar projects had operated successfully in European waters, none existed in the United States. Few Cape Codders were familiar with the ultramodern technology.
