i was told by a physics teacher about 200 mph. i think thats a little crazy. site your source if you find anything interesting.

The turbines in the source turn at up to 22 rpm (revolutions per minute) and have a diameter of 70 meters. Doing the math:
Circumference = Pi * diameter
=3.14 * 70
=220 meters.
22 rpm means the tips cover 22 times that distance in one minute which is 22 * 220 = 4,840 meters in one minute.
That is 4.84 km or about 3 miles a minute.
60 MPH is one mile per minute, so that wind turbine's tips are moving 180 miles per hour at top speed.

Now there's a plan i'd desire to choose for! placed a photo voltaic panel grouping and windmill for each abode in u . s . a . of america and create power independence for all! The Feds would desire to establish a furnish software to unfold the money around for those advancements.

Based on the description of the wind turbine I see out my window (link), on which the tips travel ~140 mph, 200 mph wouldn't be out of the question.

Whats the diameter and revolutions per minute?
A 60 foot blade travels diameter times pi per revolution.
60 x 3.14 = 188.4 feet per revolution
Multiply that by RPM for feet per minute.
If it turns a revolution in a second that is 60 RPM
60 x 188.4 = 11304 feet per minute or about 2 miles a minute
If you know the circumference and the RPM you have the answer.

Depends upon how fast the wind is blowing, the design of the blade, and how long the blade is.
