  1.  @gov.taxman1533 : "I know some valcanologist and they say unless you can stop volcanoes ,you cant stop climate change." Human carbon dioxide emissions are (very roughly) about 100 bigger than those from volcanoes.

  2. "We do this in the USA where a vast underground brine reservoir exists formed from an ancient evaporated sea" Those kinds of brine have much higher concentrations of bromine than sea water.

  3. Dehumidifying takes way more energy, especially in an arid climate.

  6. Salt is too cheap. It's not worth it.

  7. They desalinate it.

  8.  @gobil5274  It doesn't raise the average salinity of the world's oceans since no salt is added. The ecological damage from the brine is also just local. Further out the brine gets diluted.

  9. In English "Persian Gulf" is used.

  10. "There is no desert called Arabian desert" Yes, there is.

  11. Does Cairo have a good public transport? What about this new capital?

  12. The brine causes local ecological damage because it's not immediately diluted. It doesn't raise the overall salinity of the oceans.

  13.  @AmmoVanMagnus  "the Earth has not created a single NEW drop of water since it’s been formed" That's not true. Burning hydrocarbons like natural gas or oil produces water (and carbon dioxide).

  14. Why are so many of those crop circles arranged in a square lattice? One would think that a hexagonal lattice would be a more efficient use of space.

  15. That dam is for electricity generation.

  16. It would damage the desert ecosystem.

  17.  @chang.stanley  Wind can blow the salt all over the place. The desert ecosystem would not be fine.

  18.  @chang.stanley  You're wrong. It can spread far and it certainly won't aid the ecosystem. You don't want extra salinity in a desert climate where water is scarce to begin with.

  19.  @chang.stanley  No, it wouldn't. Remember that the salt would just keep piling up.

  20.  @chang.stanley  The mostly dried out Aral Sea has left behind salt dust that's blown around by wind and it's ruining crops. Maybe if you could some how dump the salt into a deep mine or something it would be fine but that's more expensive than just dumping the bring back into the sea on the spot. Pumping the brine elsewhere is not cheap and there might not be net environmental benefit depending on what you do with it.

  21.  @chang.stanley  The point was that salt dust will still result. Note that there are multiple desalination plants so it wouldn't be a single lump and the salt would be continuously building up. "Noones farming crops in the desert." This very video described how crops are farmed in the Arabian desert! In any case, my point wasn't about the crops in Saudi Arabia but the state of natural vegetation in the desert. It could easily suffer from salt dust. "The salt deposit might even be able to be mined in the future when it's built up, as it's fairly valuable sea salt." Salt prices are something like a couple of hundred dollars per metric ton. The amount of money you'd get wouldn't cover the cost of the extra handling of the brine (vs. just dumping it into the sea).

  22.  @chang.stanley  "the natural vegetation outside of the direct vicinity of the salt lump would be completely unaffected" I don't buy that. Salt dust could be spread to a wide area by the wind.
