Title: Electrical power generation using tidal power
Inventor: LEWIS GEOFFREY EDWARD
IPC: F03B13/26
Filed: 1990-02-01
Abstract: Figs. (1 and 2) show a power generating installation constructed either within a river, an estuary or off-shore between an artificial island (3) and the coast line (2). Both the main structure of the barrier and the turbine ducts have venturi shaped profiles to maximise the water velocity. The turbines are positioned within profiled ducts in the barrage (1), linking these two structures. The profiles being designed to act as primary and secondary venturis, to increase the flow rate of the water through the turbines. The cases for both bi-directional and uni-directional water flow being covered. To avoid the periodic complete loss of power generation, that would occur with estuarine and coastal installations at times around tidal flow changes, several such generating stations can be built to make use of the tidal phasing. If three such stations are suitably positioned and their outputs linked by a central distribution station, power generation will be continuous.
