“We know the wind is abundant, and we’ve known it for centuries,”

Gee really?

As a backup, the ship also has diesel electric engines.

Around 95% of the time, Le Grand says, the ship can rely entirely on sails.

On the first journey, delays meant that the ship missed the best weather window, and it needed to use fuel when it first left France. But the last 10 days of the trip were powered by the sails.

If it left “last month” on the 31st i’d say that’s about 50%, not 95.

Cool idea but humans want that crap plastic useless trinkets tomorrow, not next month. Time will tell…
