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?

    Elegant solution to brine problem: NaCl + CO2 + H2O + NH3 -> NaHCO3 + NH4Cl (products: baking soda: help reduce ocean acidification, ammonium chloride which is an excellent rice fertilizer & palm tree fertilizer). This has been known for decades (modified Solvay process aka DUAL process developed in Japan in 1980).

    Over population is the biggest problem

    what happens when you try to populate a world with 7.75 billion people that can effectively sustain say about 6 billion people? Well, either you figure out how to create technology to boost sustainability or 1.75 billion people are going to die. How many people can earth support? There is definitely a limit cause this planet has a finite size & finite resources. We can't just over-populate our world without consequences.

    For brine, just pump it a bit into the desert, let the water evaporate, and build magic salt mountain.... you can ski on it all year.

    Generally, 2-8 million gallons of water may be used to frack a well. Some wells consume much more. A well may be fracked multiple times, with each frack increasing the chances of chemical leakage into the soil and local water sources

    Mixing technologies could lower the price of desalination while upping the efficiency just like how Jeffrey Epstein was murder in prison

    desalination should taken as an option, firstly we should try to harvest the rainwater, concerning upon the recharge of ground water and moreover build some technology to collect the vapor that get evaporated from the water sources like waterfalls(like Niagara falls mentioned in the video) and also by waste water management we could reduce the situation where the desalination of brine would come into practice and the task would be done more efficiently.

    If it rains where you live and you have a few cubic meters of spare space it should be mandatory to have a rainwater tank to wash your clothes and flush your turds away.

    any process that destroys the marine environment is selfish and stupid .

  • A-Disappointed-Sigh

    why not take that brine ... desalinate it again and again... then evaporate it (either to collect the steam for more water or use the power of the sun to evaporate) and then you have two products to sell: a lot of water + seasalt. Everyone needs water but people need salt too.

    I think when we have a solution that can produce energy cheap and safe or maybe if we have unlimited amount of it, we'll have solution of it

    Well ,here comes another simple yet destructive solution... Means if u hv destroyed one resource,no worries, move over to the other.. incredible
    Rather we should be focusing more upon the rainwater harvesting n bringing the climatic cycle back to its normalcy..!!!

    Yea its expensive to do reverse osmosis....but what about thermal desalination? They dont even do it lol would cost nowhere near as much and is a natural method. Wouldnt cost as much energy or anything. Like wtf.

    • Adam Jones
      Adam Jones 2 days ago

      Or how much water is available to drink? Also, how can water be so scarce? Can land not be hydrated via sea water? Here in Wales we have salt marsh sheep and lamb's that graze the salt grass. I'd love to see Africa and India mainly come into some sort abundant water source.

      Surface water will not be enough for this ever growing population for growing food, cleanliness etc. Desalination will have to be from renewables (green hydrogen) and the brine needs to be used for salt production, not fed back into the sea. The tech is there, it just needs the will and capital to be implemented.

    ATAHUALPA867 2 days ago

    We must adapt and do a huge effort not to waste . Toilet and showering worse ways to waste it . We must help ourselves.
    Desalination is not new but up to now is seen as way to save this planet and people of running out of water..

    The energy consumption is not a problem. Most people, when asked if they want next year either use disco ball in their appartment, or drink for a next year, they tend to pick the most survival centric issue, wich the drinking really is.

    Yes - IF the ocean's water is kept clean, this is the answer. However, rivers , which constantly flow into the ocean and run around the globe faster than one realizes, have to be kept free of industrial waste, nuclear waste, and other pollutants..

      @SV K All things are not equal by any metric. India and China are far and away the biggest polluters on the planet and it isn't even remotely close. Those two countries pollute more than every other country in the world combined. Even then the margin is ridiculous.
