From Two Bit da Vinci.

Every single day, 100,000 cargo ships burn some of the dirtiest fuel on the planet to move 90% of everything you own. But for 5,000 years, they did it for free — using wind. So why did we stop? And more importantly: are we finally going back?
In this video, we break down the three technologies bringing wind power back to modern shipping — Flettner rotors, rigid wing sails, and a full-blown commercial sailboat that just crossed the Atlantic carrying real cargo.
We cover:

How Norsepower’s spinning cylinders use the Magnus effect to cut fuel by up to 25%
How BAR Technologies — born from America’s Cup racing and Formula 1 — built a three-element airplane wing for cargo ships
How the Neoliner Origin became the world’s first modern wind-powered cargo ship, survived a North Atlantic hurricane on its maiden voyage, and still delivered on time
The actual math: can a 265-container sailboat compete with a 12,500-container mega-ship on a per-container-mile basis?
