Energy has to come from somewhere. It's not like a nuclear reactor where it starts in place. With hurricanes, we're talking about the energy in area of the entire ocean being concentrated.
Yup. That's really the only way to take energy out of the ocean. If we could somehow fill the surface of the Atlantic with turbines and wave-energy machines, perhaps we could end destructive tropical storms. But the amount of energy involved is astonishing and difficult to reason about.
Better off creating hurricane-proof windmills.
