Claim:
A windmill, comprising: a nose assembly configured to accelerate an inlet air stream so as to create laminar flow around a nose body of the nose assembly and to direct the accelerated air stream into a first series of fixed vanes; a turbine wheel having an array of turbine blades configured to accept the accelerated air from the first series of fixed vanes; and a tail assembly having a tail body and a second series of fixed vanes configured to accept an exit air stream from the turbine blades and to direct the exit air stream away from the windmill, wherein the first series of fixed vanes are curved to accelerate the inlet air stream and turn it less than nine degrees tangentially toward the array of turbine blades, wherein the array of turbine blades are curved more than ninety degees so as to reverse the direction of the air stream, and wherein the second series of fixed vanes are curved so as to direct the exit air stream towards the tail body.
