Multi-turbine airflow amplifying generator

An energy generative device for harnessing airflow comprising:

• a) at least one turbine 16;
• b) each said at least one turbine 16 comprising a proximal rotor 24, a distal rotor 30, and means to associate 152 in general coaxial alignment said proximal rotor 24 and said distal rotor 30 spaced apart one from the other;
• c) a proximal channel 26 comprising an inner surface 27 for guiding airflow first to said proximal rotor 24 and then said distal rotor 30;
• and
• d) a distal channel 32 for guiding airflow to said distal rotor 30.

An energy generative device for harnessing airflow comprising:

• a) at least one turbine 16;
• b) each said at least one turbine 16 comprising a proximal rotor 24, a distal rotor 30, and means for generally coaxially aligning and associating 152 said proximal rotor 24 and said distal rotor 30 spaced apart one from the other;
• c) a proximal channel 26 comprising an inner surface 27 for guiding airflow first to said proximal rotor 24 and then said distal rotor 30, a leading portion 27a and a following portion 27b separated generally at the proximal rotor 24;
• d) a distal channel 28 for guiding airflow to said distal rotor 30 wherein said distal channel 28 opens into said following portion 27b ;
• and
• e) a diffuser 35 positioned in fluid communication with the distal rotor 30 to accommodate air passing therethrough.
