Originally designed in 1983, the 100-foot boat dubbed the Energy Observer began its life as a competitor in open-sea sailing races.
Now, the vessel has been converted into a self-fueling boat by skippers Frederic Dahirel and Victorien Erussard, with the help of a French research institute.
Valued at a whopping $5.25 million, the Engery Observer uses wind turbines, a hydogen fuel cell system and solar panels to power its journey around the world.
During the day, the boat will use the sun and wind to power the vessel, and it will produce its own hydrogen through the electrolysis of sea water in the evening.
The boat just embarked on a six-year, round-the-world journey from Paris, France last week. According to the Associated Press, the Energy Observer's designers hope the boat will be a model for emissions-free energy networks in the years to come.
