Energy from the Wind - Practical Answers

This means that the power density in the wind will range from 10W/m² at 2.5m/s (a light breeze) to 41,000W/m² at 40m/s (a hurricane).

so assuming 100% eficiency from this design, and hurricane speed winds you're talking 24,400 square metres of blade area.

(take into account that this is ultimate bodge physics and I really have no idea what I'm talking about, these are numbers I pulled off a random page on the internet)

Any idiot can face a crisis - it's day to day living that wears you out.
