The wind turbine has had a singular history among prime movers. Its genesis
is lost in antiquity, but its existence as a provider of useful mechanical
power for the last thousand years has been authoritatively established for
recognition as historical fact by most professional historians of technology.
The windmill, which once flourished along with the water wheel as one of the
two prime movers based on the kinetic energy of natural sources, reached its
apogee of utility in the seventeenth and eighteenth centuries. Its use then
began to decline, as prime movers based on the thermal energy from the
combustion of fuel took precedence. Steam engines, steam turbines, and oil and
gas engines provided more powerful and more compact machines, adaptable to a
multitude of uses other then just the grinding of grain and the pumping of
water. These new heat engines also were continuously available rather then
subject tot he vagaries of nature, and they could be located at the job site
rather the requiring that the job be brought to them.
