Abstract:
1. A generator for generating energy from a moving fluid, the generator comprising a duct and a diaphragm ( 5 , 15 ) placed inside said duct, said duct comprising walls including two faceplates ( 1 ) between which the diaphragm ( 5 ; 15 ) is placed so as to be subjected to the action of a stream of fluid penetrating between the two faceplates, wherein the two faceplates diverge from an inlet ( 2 ) of the duct towards an outlet ( 3 ) of the duct so as to cause the diaphragm to deform under the action of a stream of fluid in the form of a traveling wave that moves from a leading edge ( 6 ) of the diaphragm situated at the inlet ( 2 ) of the duct towards a trailing edge ( 7 ) of the diaphragm situated at the outlet ( 3 ) of the duct so that the trailing edge of the diaphragm is driven with transverse oscillating motion, and means ( 11 , 12 ) for making use of said motion being coupled to said trailing edge.
