  • Today, one out of three people don’t have access to safe drinking water. And that’s the result of many things, but one of them is that 96.5% of that water is found in our oceans. It’s saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than one percent of it is available to us. So why can’t we just take all that seawater, filter out the salt, and have a nearly unlimited supply of clean, drinkable water?

    This is my favorite solution. Also, there's several ways to desalinate water. For RO desalination they should use the effluent for industrial purposes.

    Thermal desalination can use stainless steel pipes, one way valves and magnifying glasses or fernel lenses to use sunlight. By making a mechanical system that only needs daylight, existing resivoirs could be used. It's just to inexpensive of an option, so nobody talks about it.

    Use the wave energy. Harvest its kinetic energy to "distill" the salt water. Kinetic energy of the waves need to be converted to heat. Distilled water is similar to rain water and can be used for irrigation. More details at: https://www.youtube.com/watch?v=yj5wCoVhD-I

    Let’s do that, we already dumped all the trash in the oceans. GOD is looking down on us and thinking, I should’ve had given Earth to the Martians. Humans doesn’t deserve it.

    the only energy problem real is our brain.... u have sun to desalinate water and take salt the same time without any energy needed.... we are just dump... we have problem with the ice meting so take water out of sea.. desalinate it with sun vaporasion and take the salt.... whats ur problem????

    No it can't solve our problem boz people don't understand what they have and they are divided by the country , by the religion and buy the availability of resources they can buy and that's why we will loose
    There is a chance we can win by acting all together as a world not as individual country
    Or etc

    no, it will probably just ruin the sea. given how literally every other thing humans have ever done has turned out, it will just further hasten the biological death of the planet.

    We should have a system sucking salt water from the ocean use geo thermol heat to change the water to fresh and dump in to a river that uses it to create hydro electric before it comes to rest in a Reservoir where it can than be used for water supply

    Couldn't some enterprising chemists figure out uses for some (or all)of the brine before sending it back to the sea?

    Why not just store the brine and turn it into pure salt ? It's not rocket science. It's just extra lazy to dump it back into the ocean.

    Does reverse osmosis not lead to distilled water?

    If salt is extracted so are all the minerals I imagine.

    Why don't they just do a two part system where they separate fresh water and brine
    Then they remove salt content in the brine until it reaches sea salt level
    And they reuse and refine that salt as a product

    Desalination will happen. It doesnt matter how much it costs. You cant drink money. Various countries have had bread riots in the past. Water riots are equally realistic unless steps are taken.
