Wonder why they changed?

Effectiveness and efficiency. Wind is likely making a comeback on ships, interestingly enough:

Quote:Rotor ships, sometimes called Flettner ships, have been around a while. The big development now is that the major players in shipping are taking the idea seriously. Yesterday the shipping colossus Maersk installed 100-foot-tall rotors on one of its tankers, the Pelican, according to the Wall Street Journal.

Maersk thinks the advanced sails could cut its fuel costs by 10 percent. That may not sound like much, but consider that the Danish mega-corporation spends $3 billion annually on fuel to move the world's cargo, so we're talking about $300 million. If the Pelican tests succeed, the Maersk could try out rotors on other vessels and turn more cargo ships into hybrid sailboats.

Oh, I see. I was talking about wind as the primary mover of ships, like in the Spanish Armada, and you counter with an auxiliary use to reduce costs 10%. Clearly apples and watermelons

Every industry that used wind power has go to other sources for power. Why?

I think wind is great as an auxiliary. As a sole or primary source, not so much..
