The message . com
from "robgraham" contains these words:

Well, looking at the spec for the gennie he is talking about it
**claims** that it produces its 2.5kw for 5m/s wind, equivalent to
force 3, which is not a strong wind at all.

Trouble is the energy available is related to the cube of the wind
speed. Drop from Force 3 to Force 2 and most of the output's gone.
