turbines can be engineered to produce pressurized water, instead of electricity.
In this simple and cheap solution the propeller drives directly a pump either
underwater or above water. Then a flexible water pipe goes directly from the
turbine to the shore.
m³ of water produced results 3 times cheaper than with a motor-pump.
solutions are implementable:
irrigation water from river water
fresk drinkable water from river water
fresh drinkable water from sea water (later)
