Ummm… 10 knots * 200 = 2000 knots. I don’t think so lol.

First of all, kinetic energy scales with the square of an objects velocity.

Second, since we’re not talking about a single object but a continuous stream of fluid, increasing the air speed not only increases the enegy per unit mass of air, but also the units of air per second that pass through the turbine. Which means that the amount of energy extracted scales by the cube of the wind speed.

So, more like going from 10 knots to 60.
