Note: most 'live' wind sessions produce more than this. For example, in 25-30 knot winds we have seen nearly 30 amps coming out of these babies.

WIND WATT FORMULA
W = 1/2 x P x v3 x (pi) x R squared
Where W = the power of the wind measured in W (Watt).
P = (rho) = the density of dry air = 1.225 measured in kg/m 3 (kilogrammes per cubic metre, at average atmospheric pressure at sea level at 15° C).
v = the velocity of the wind measured in m/s (metres per second).
(pi) = 3.1415926535
R = the radius (i.e. half the diameter) of the rotor measured in m (metres).
