• a body having
• a front;
• a rear;
• a bottom;
• two sides;
• an airway formed in the body, being substantially J-shape and having
• two side walls;
• a curved part having
• a proximal end;
• a distal end;
• and
• an opening formed at the distal end of the curved part of the airway, communicating with the front of the body, substantially facing upward and having a front edge;
• and
• a longitudinal part having
• a top end;
• and
• a bottom end communicating with the proximal end of the curved part of the airway;
• and
• an overhang formed on the top of the body, hanging over the airway between the side walls of the airway and having
• a top;
• a bottom;
• two sides;
• a pendent shelter formed on and protruding down from the bottom of the overhang, hanging between the proximal and distal ends of the curved part of the airway;
• and
• an air window formed in the overhang and communicating with outside and the top end of the longitudinal part of the airway;
• and
• a turbine generator assembly mounted on the overhang and having
• a housing mounted on the overhang and having
• an air channel formed through the housing, communicating with the air window in the overhang and having an inlet and an outlet,;
