The ship is circling the planet without the benefit of fossil fuels.
The tour: The Energy Observer is a Toyota-sponsored vessel on a six-year global tour powered by solar, wave, hydrogen, and wind (yeah, this one isn’t that revolutionary) power. During that time it will visit 50 countries, including Italy, where it will stop today in Venice.
How it works: The ship removes the salt and ions from ocean water, and then separates it into its base elements: hydrogen and oxygen. The hydrogen is stored until it’s needed for fuel. Solar panels and wind turbines supplement the power.
