Apparatus for power generation

A power generator for use in a bore, the power generator comprising:

• at least one drivable member;
• at least one generation apparatus;
• the generation apparatus including,
• at least one generator magnet configured to produce a magnetic field;
• at least one electrically conductive member located or locatable within the magnetic field;
• and
• a housing including an axial length, a cylindrical shroud member defining a cylindrical hollow, an axial inlet and a plurality of radial outlets arranged circumferentially around a side wall of the housing, and a dome shaped protrusion defined by the cylindrical shroud member and located inside the cylindrical hollow of the cylindrical shroud member that protrudes axially inwardly towards the axial inlet to direct the flow radially out through the plurality of radial outlets, wherein the plurality of radial outlets are located along the axial length of the housing prior to the generation apparatus so as to direct a flow of fluid out of the housing in a radial direction;
• wherein the drivable member is drivable by fluid flowing from the axial inlet to the plurality of radial outlets of the housing so as to produce relative motion of the at least one magnet and the at least one electrically conductive member in order to induce a current in the at least one electrically conductive member.
