I think tidal canals would be the better option than pipelines. Dig channels deep and wide enough that the water of the seas actually mingle, letting dissolved salts spread out into the wider ocean.


For that "deep and wide enough" to work out, just how deep and wide would the canal need to be?

Such mingling happens at the Dardanelles - but it's half a mile or so wide, and ~180 feet deep.

With quite a bit of extra digging this could get us an alternative to the Suez Canal which I believe many countries would be interested in and would strengthen global trade.


They already added lanes to the suez canal and I imagine it'd be way more cost effective to keep expanding those as needed.


There is a political advantage not to be solely depending on Egypt.
