Abstract

En nedihulls elektrisk strømgenereringssystem inkluderer en strømningsbegrensningsiimretning (48) som variabelt begrenser strømmen gjennom en åpning (40), i det begrensningsiimretningen vibrerer som respons på strømning gjennom åpningen og begrensningsiimretningen dermed vekselvis øker og reduserer strømmen gjennom åpningen; og en elektrisitetsgenereringsiimretning (54) som genererer elektrisitet som respons på vibrasjon av begrensningsiimretningen. Et annet nedihulls elektrisk strømgenereringssystem inkluderer en strømningsbegrensningsiimretning som vibrerer som respons på fiuidstrømning gjennom en åpning, i det begrensningsiimretningen dermed vekselvis øker og reduserer strømmen gjennom åpningen; en trykkdififeranse over begrensningsiimretningen som variabelt fiorspeimer begrensningsiimretningen fior i økende grad å begrense strømmen gjennom åpningen.
