    I don't want to spoil it for you so will not tell you this moment how this is to be done, but listen up, science has a solution. I hope you understand her accent. She makes water seem amusing.

    So, who is worried they won't get plenty of delicious water?

    Israel's Water Worries Return After 4 Years of Drought
    October 23, 2017 — It was a source of national pride — technology and discipline besting a crippling lack of water.

    So. Africa faces severe water rationing...

    Wichita Falls didn't get much water for a decade or more, and their source, Arrowhead Lake was just about dry.

    So they built a treatment plant that takes in sewer water and outputs pure, potable water, at considerable expense.

    Then the steed found the flat rock, and the lake was filled up in a few days, and the desert turned green.

    But a lot of those folks now think water is precious, and even though they have plenty, don't use much water anymore.

    I have been through Texas but one time on Highway 40 so you don't learn too much just driving. I was running late and was headed to Branson, MO and missed the huge steaks you have at that famous restaurant on 40. My first plan was to stop on the way back to CA to fill in the gaps. I did not come close to Wichita Falls. My plans changed in MO so I headed further east to St. Louis and reversed but on highway 70 so did not fill in the gaps. But it was worth driving 70 and seeing things on that road. I once was on a train that carried me through TX but a train is not a good way to see very much as I then learned. I have flown into Dallas a couple of times.

    Well, I didn't watch the video, but water is extremely weird, and because of that life can exist. Most lower level biology classes cover this topic. I know getting my biology degree I must have heard at least 4 different lectures on how weird and wonderful water is, and how important that is for life. One example is that solid water is less dense than liquid water, which means ice floats. That's very important for life.

    Indeed sir. Ice is very important for I would be miserable without ice cubes in my iced tea, during the hot summers here in the south. So ice is very important for life, at least a quality of life. But I can still recall ice boxes from my youth, where people bought blocks of ice to put in those ice boxes to keep foods chilled and somewhat preserved for a few days. I still remember what these ice boxes smelled like, since many were made of wood.

    So, what does this city in south africa not use desalination, since they are close to an ocean?
    Lest we forget, it is now thought by the experts that the great Mayan civ. collapsed due to years of drought. Some of us act as if drought never occurred prior to man putting co2 into the atmosphere. A drought and poor land management created the dust bowl during the great depression. Man will always suffer droughts, climate change or not.

    You missed my point. The important part about ice and water being weird in terms of ice is that ice floats. In most materials, the solid version is more dense than the liquid, meaning the solid version sinks. Think about what would happen if ice sunk? Nothing could live in a frozen pond, for example.

    Having survived Hurricane Ivan and lived in it's aftermath, my wife and I have concluded that ice is civilization. Ice is very necessary for the quality of life down here.

    Desalinization is very expensive is the simple answer. The Saudis use it to some degree, but they are extremely rich. South Africa is far from rich.

    Yes, and water expands when it freezes into ice. Water has some interesting properties.

    With the the ice melting and ice breaking off south of South Africa, one wonders why they don't use a tug boat and bring some of that ice shelf ice up to this place you are talking about. Park it off shore and use it for fresh water. Of course I am saying this in jest.

    I thought south africa at one time was prosperous, at least for the white folks? But I know very little of that place. I do know that long droughts can affect water supply in most places. It can even crash civilizations as it did with the Maya. But the rains eventually came back and it was too late at that point. Probably more common than we might think?

    I remember when ice was a luxury here in the South, when I was really young. At least in the rural areas. We used to have a dairy and before the chemical plants moved here, we had overflowing wells. Water that was under natural pressure and flowed up in great volume from pipes sunk into the water table. They were all over the place here where I live. We had a concrete vat, about 4 feet deep that our overflowing well flowed into, with really cool water even in the summer heat. This was built to put our raw milk in after milking, in big cans, to keep it cool until the milk truck picked it up. So we didn't need refrigeration to produce milk. As kids we would swim in this concrete vat in the summer when cold well water felt good in these hot summers we have down here. After the milk truck ran of course. lol

    Once the chemical factories moved here, they used so much water that it stopped the hundreds of overflowing wells here from flowing. The stream coming from the pipe over a couple of years reduced down to just a trickle, until one day the water no longer flowed. We have none left today, but I remember them well. Of course you could still pump water from these wells, but the pressure was gone. We stopped the dairy operation at this time.

    I am glad I live in a part of this nation where water is not a problem. If my water even goes out from the system we are now on, I can go out to my backyard, take a steel cover off of the well here, and have access to well water. After being raised up on well water, from deep wells, I still cannot drink the treated water supplied by the local water company. I never liked the taste of chlorine bleach I guess.

    The Saudis once contemplated getting an iceberg, and using it for water. Same problem as desalinization--expense.

    Using tug boats is that expensive? I still think if you do not have enough water, you have to come up with the funds to solve the problem. Or move.

    If you had a straight shot, the distance from Saudi Arabia to the Arctic circle is 3000 miles. An ocean going tug goes about 10 miles per hour. That's 300 hours, at about 4000 gallons of fuel per hour.

    Not too bad, as the saudis could work up a deal and get that fuel at cost not retail? lol

    I was astounded to see the MPG of a tug!! We need a nuclear powered tug, running on steam turbines with superheated steam. I would imagine it would take much larger tug to tow a huge iceberg!

    The 10X difference in the population estimates could be partly due to:
