If a small wind turbine was moving at 100 mph could it produce about three kilowatts of electricity?

   Why would a wind turbine be moving at 100MPH?
   If you mean wind speed of 100MPH there is a lot of energy in that wind. I am guessing about a 4ft diameter turbine could produce 3KW depending on the design.

   You must be more specific, how small power generated is a function of the mass pushing the alternator and the force of the wind etc.

   however a 10 foot diameter will produce 1kw+ at 12 MPH

   no small wind turbine will spin at 100 mph, their peak efficiency is achieved in winds of about 20 mps. Kilowatt output is measured over time, the correct output is kilowatt hours. But it depends on the size of the turbine. Some small turbines, operating at peak efficiency, can product three kilowatts in about 2 1/2 hours.

   But if the wind speed is too high, the turbine may ‘furl’ or change direction to to reduce the cycling speed.

   You had better hope that the blades are moving at much less a rate than that, and the rest of the generator not at all! I think you be lucky to get 1 Kw out of any wind generator. They are ugly, a waste of time and energy INefficient!
