Apparatus for power generation comprises a watertight housing 12, an electrical generator 13 located in the housing 12 and at least one rotor 14 located outside the housing 12 with means, preferably a shaft 16, linking the, or each, rotor 14 to the generator 13 so that it can rotate about a first axis A to drive the generator 13. A shroud 18 extends between a first section 19 attached to the housing 12, and a second section 20 remote from the housing 12, the shroud 18 serving to at least partially enclose a plenum P and incorporating first means whereby the apparatus can be mounted on a base 21 and be rotatable relative thereto about a second axis B, and second means whereby the plenum P can be isolated from water in which the installation is immersed. The invention further provides an installation including one or more of the apparatus. |
