Abstract
A turbine generator (1) comprising a rotatable shaft (10), a plurality of spaced apart parallel discs (8) carried on the shaft (10) so as to be rotationally fast therewith, and power generation means connected to the shaft (10) so as to be rotated thereby, the circular surface of each disc (8) having a plurality of recesses, dimples (26), grooves (27), vanes (28) or projections formed therein so as to increase the surface area. The turbine generator (1) further including a debris removal system for removing debris from between the discs (8) and a plate (6) for controlling the rotational speed of the discs (8). The plate (6) extends longitudinally parallel to the shaft (10) across the plurality of discs (8) proximate to the outer surface thereof and also extends partially around the circumference of the discs (8), below the surface of the water (18) and on the downstream side of the disc cluster (2) which, in use, is submerged in fluid (18).
