Can Sea Water Desalination Save The World?

  • Published on Oct 16, 2019
  • 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?

    if you move or live in a area like a desert and complain about not having water, this problem is YOUR fault. don't frigging live there. modern humans are nitwits. just because you can drive to a location doesn't make it a good place to live. if the earth wanted you living there it would provide you with water.

    Hofmann voltameter
    Hofmann voltameter is an apparatus for electrolysing water, invented by
    August Wilhelm von Hofmann in 1866. It consists of three joined upright
    cylinders, usually glass. The inner cylinder is open at the top to
    allow addition of water and an ionic compound to improve conductivity,
    such as a small amount of sulfuric acid. A platinum electrode is placed
    inside the bottom of each of the two side cylinders, connected to the
    positive and negative terminals of a source of electricity. When current
    is run through Hofmann's voltameter, gaseous oxygen forms at the anode
    and gaseous hydrogen at the cathode. Each gas displaces water and
    collects at the top of the two outer tubes.

    check out the wave powered desalination plant on Garden Island in Western Australia. Wave power is used to directly pressurize the salt water, and thn it still comes out with enough pressure to run turbines to supply the electric needs of the plant.

    No...The answer is no. It takes way more energy to desalinate water than to treat fresh water. If Fusion becomes a reality then it becomes viable. Otherwise you are burning a lot more dead dinosaurs to make your fresh water than before. There is no free lunch in Thermodynamics dumb dumbs.

    Of course it works,look at Australia they have the worlds largest desalinization plant in the world.San Diego now has a desalinization plant a Ditto copy of Australia but smaller.The military did it back in ‘90-‘91Operation Desert Shield/Desert Storm that’s how we got water 💦 the 1st month in country right out of the Port of Jubail Saudi Arabia..

    Can the brine be used for salt if you evaporate the water from it? I feel like it may be different.

    I've been hearing this 1% talk for years now. If there was really only 1% of fresh water that we have access to then i would think it would have been used up by now.

    Why not build greenhouses with curved or domed ceilings in arid or desert areas where they might need the water most in the first place, fill them with saltwater, and collect the evaporated fresh water as runoff the way the planet already does it? Then we could collect the solid salt as a byproduct to sell, use little energy other than transportation costs, and not expose other environments to brine.

    PIPER DOUG Day ago

    So one group is talking about glacial melt desalinating the oceans and then another is complaining about brine..... they mentioned that salt readily disperses into the water and combines so it will balance out. i'm afraid as the "goldie locks" zone moves further away from the equater then staying where you were will become more challenging

    Desalination Plants have done a lot of good work for the society by filtering out drinking water from the extremely saline and polluted sea water. The brackish water which is filtered out and sent back to sea beds by desalination plants is harmful for the marine plants and animals.Instead of this, the desalination plants should have a permanent set of storage vessels for brackish water from where on the salted H2O could be further sold to manufacturers of table salt,baking soda & detergents for further salt extraction or even be sold to car battery manufacturing factories,tanneries, laboratories, chemical industries,poultries,naval shipyards, nuclear power generating stations,etc.

    We have technology that puts high-tech cameras on far away places like Pluto, and asteroids. OF COURSE WE CAN PURIFY SEA WATER! Israel is doing it. A system using gravity and a series of micro-filters is quite feasible. Nuclear Power provides unlimited heat for distillation. We needs laws that force this technology! MEXICO has no problem with water: Evert town has several water purification stations.

    Quadrillions of gallons of water in the ocean, and you think a few thousands of gallons of brine will harm the ocean. Do scientists know what concentration gradients are? The brine that is dumped will equilibrate once dumped into ocean where the laws of concentration gradients take place. Dump it in the ocean, and stop complaining.

      Also, can't you make table salt after filtering the brine from micro-plastic parts? there are other uses for salt like conducting/preserving heat (with liquid salt), which can be used in a heliostat power plant for example

    • kobi2187
      kobi2187 3 days ago

      not at all stupid. and you can capture the steam as well, and it becomes good water. just that you have to boil it. you can concentrate the sun's light with mirrors, or just have a giant magnifying glass like they had in lighthouses. (in the video they assume you'd use electricity so they thought it's not an option- just narrow mindedness I guess)

    BENTLE7 3 days ago

    The remainder brine that’s left from the desalinated water.. can’t you just naturally let the remainder water from that brine evaporate and then you’ll be left with salt? You don’t have to harvest every mm of water.. essentially you’ll get clean drinking water, some water that evaporated and will rain back down.. and a cup of salt..

  • sparkey
    sparkey 4 days ago

    I believe because of regulations, and cost to meet them, desalination isnt happening in some areas that would bennefit from it.
    For instance.
    Ventura CA. is a costal city, it is getting ready to treat sewer water enough, so that it can be pumped down into the local aquifers. Then it will magically be called safe drinking water. The practice is called (toilet to tap). Things like pharmaceuticals that can,t be filterd, or treated out, are now going to be part of the water supply there. Not only well this water will be for home use it will also be used to irrigate crops potentially contaminating food grown there. Not to mention this is just a humilliating circumstance for the people in this area.

    Wouldn't it be more cost effective to invest in floodwater areas, catching /storing/pumping the water , and after filtering it to put it to good use wherever needed, it's being done with oil and gas already.

    A completely solar dome-thermal was planned in San Diego in the 50s, and chopped off. It was easier for the neolibs to rob Native Americans of their water rights than spend a nickle to make the city independent of outside water. Salts would have been ground and boxed, then sold to defray costs. Like solar, the more people using reverse osmosis and thermal the cheaper it becomes, the less damaging to the environment. Yes, it is the answer, no matter how others twist the truth. Ask them about world population. Most seem to think all peoples in 3rd world nations should die and stop polluting the earth for whites first.
