The average megayacht burns more than 130 gallons of fuel per hour—and that's when the boat is idling. Needless to say, megayachting is not the most carbon-friendly of billionaire pursuits.
But now, the folks at Feadship have come up with a more green-friendly alternative: the hybrid megayacht.
Feadship, the prestigious Netherlands-based yacht builder, has just launched "Savannah," the world's first true hybrid megayacht. On the outside, the 273-foot ship looks like a typical diesel-guzzler, with five stories, a swimming pool and massive decks.
But a peek under the hood (or hull) reveals a ship with a highly advanced power system. It's got a single diesel engine (instead of the usual two), three diesel-electric generators and a cluster of giant batteries.
