I propose a renewable energy scheme where a tidal lagoon is partitioned into a ‘high’ lagoon and a ‘low’ lagoon by a dividing wall, which houses turbines which continuously generate power as sea water flows from the high lagoon to the low lagoon.
At high tide, the sea-gates of the high lagoon are opened and the high lagoon is filled up to high tide level.
When the ebb tide begins, the sea-gates of the high lagoon are closed and remain closed until the next high tide.
At low tide, the sea-gates of the low lagoon are opened and the low lagoon is emptied to low tide level.
When the flood tide begins, the sea-gates of the low lagoon are closed and remain closed until the next low tide.
The sea-gates are functionally identical to one-way flap valves and may be engineered as such.
