Abstract

An underwater turbine arrangement is herein described. The water driven turbine comprises a housing having a shaft mounted for rotation about an axis therein. The shaft includes a plurality of flights arranged to drive rotation of the shaft. Mounted onto the housing is a funnel having a mouth greater in size than the housing and a discharge of similar size as the housing. Thus, water entering the funnel is constricted before being passed onto the housing, thereby increasing the force with which the shaft is rotated, thereby increasing the amount of energy produced.
