Tidal flow modulator

Abstract

Tidal modulators are described by which the tidal flow may be started, stopped, or regulated by movable parts that open, shut, or partially obstruct one or more passageways to modulate the tidal flow so as to enhance capturing its energy.

1 . A tidal modulator, comprising:
 a center valve; and   a pair of butterfly valves, each of whose axial center being oriented in a first plane that is in parallel to a second plane of an axial center of the center valve and being further oriented in a third plane that is perpendicular to the second plane of the axial center of the center valve, the third plane being collocated with respect to the first plane at a 90 degree angle.   
     
     
         2 . The tidal modulator of  claim 1 , wherein the center valve includes an elongated blade and each butterfly valve includes another elongated blade. 
     
     
         3 . The tidal modulator of  claim 2 , wherein the elongated blade of the center valve is configured to be thick in the center and tapered towards its termini. 
     
     
         4 . The tidal modulator of  claim 2 , wherein the elongated blade of one butterfly valve is configured to be thick in the center and tapered towards its termini. 
     
     
         5 . The tidal modulator of  claim 2 , wherein a terminus of the elongated blade of one butterfly valve is in proximal relationship to a first terminus of the elongated blade of the center valve and another terminus of the elongated blade of another butterfly valve is in proximal relationship to a second terminus of the elongated blade of the center valve. 
     
     
         6 . The tidal modulator of  claim 2 , wherein a terminus of the elongated blade of one butterfly valve is in distal relationship to a first terminus of the elongated blade of the center valve and another terminus of the elongated blade of another butterfly valve is in distal relationship to a second terminus of the elongated blade of the center valve. 
     
     
         7 . The tidal modulator of  claim 1 , further comprising a quartet of columns. 
     
     
         8 . The tidal modulator of  claim 7 , wherein an axial center of the center valve is equidistant to termini of the quartet of columns. 
     
     
         9 . A tidal bridge comprising a tidal modulator as claimed in  claim 8 .
