Simpler 'Tidal Energy Cell' (TEC) systems have a flexible, air-tight discoidal vessel 10, fig.4, from which air is expelled to drive a turbine as the vessel is compressed by the rising tide and into which air is drawn from above the surface at low tide through pipe(s) as the compressed vessel recovers shape, also driving a turbine. Larger systems have a pair of generally rigid, shallow opposed domes, 12, fig.7a, separated by springs 3 and a flexible seal 2. They may exchange air/gases/fluids with pressure chambers 11 during rising/falling tides, driving turbines 8 via valves 9. Several TECs may be arranged in 'tidal stacks' (fig.8) at various levels on columns or cables rising from the seabed, and may exchange fluids with central chambers built around columns at various heights. Also disclosed are Inter Tidal Energy Reservoirs and Generators (ITERGs) (15, fig. 10) which are wide containers open from above so that water drives turbines as the containers fill and empty. TECs and ITERGs may be provided on platforms, fig. 10, combining multiple renewable systems, eg including wind turbines. |
