A brief factual video about H2O as an introduction: https://www.youtube.com/watch?v=VIaw5mCjHPI
This discussion thread is dedicated to to the many facets of H2O and how we may conserve, share, transport, desalinate etc. and profit from this essential life giving resource that is now approaching a global crisis in many areas of our planet. Best2ALL!-Ben

This is a pretty neat idea. http://www.watercone.com/index.html

Scorpio posted this link on the regulus thread;
http://www.fastcoexist.com/1678078/watch-a-tugboat-drag-an-arctic-iceberg-to-parched-people-half-a-world-away-video

and posted about the possibility of icebergs as source of water. Of course with sufficient time and money many things are possible and what is not possible today may be tomorrow. The link gives some good thinking on how to move bergs to where they are needed, especially in choosing the right type and then putting a barrier around it ,although they only went so far as halfway. If said wrap was multi layer with an insulating layer it would be much better in forestalling melt, which is fairly rapid in warmer water.
Further if a chunk of sea ice as shown was moved from antarctica to say Arabia or Persian gulf the distance and time would be far less ( a trip from Greenland would have to circle Africa and cross the equator twice) and cross the equator only once. A berg
with a height of 100 feet would extend 400 feet below water so that would need a barrier
500 feet in one dimension and probably close to a mile in the other, to wrap a berg a quarter mile in length and 3/8th mile in width. The link showed a tug using a long line to tow a berg and that is needlessly inefficient,pushing is better and two vessels ( one on each side) propelling it is best. If your tow ships were equipped like Reagan class
aircraft carriers with nuclear plants on board to supply lower cost propulsion might
be economically practical. That would however need a huge outlay of financing for the equipment.. $ Billion or more. assuming that you only lost half the berg to melting you might reach delivery with an ice block that reached 75 feet above surface so it would extend 300 feet below. Where are you going to find a port with that water depth? How do you isolate the fresh melt water from the surrounding salt? Perhaps the barrier used in towing could be used if it extended well down and separated from the berg by a suitable distance to allow pumping to shore via flex pipeline from area of deep water. It is possible.
Desalinization for now is probably least cost per gallon,,,especially if using modern solar still technology in areas with a lot of solar heating. Osmosis filtration is probably second.
Harvesting water from warm humid air via chilling is also good. IMHO those methods are likely to return most on investment.

$BWEL Doing some DD on list and could not find much info on BWEL.
I did run across this FYI http://microcapclub.com/2011/10/jg-boswell-the-most-interesting-small-cap-you-never-heard-of/

$AWGI is a stock mentioned by Dr. KSS for consideration. The company has a method of water harvest from the ambient water vapor in the atmosphere. The science for doing this is well known for a long time so patents would have to be on novel ways of implementation. From what I can infer they use a structure/greenhouse probably one of those plastic film grow houses you often see growing early or late season veggies. Irrigation of the plants lets the air become quite moist and normally they are ventilated but ventilation would not be used in a collection system.
That is good means of having a micro climate with near saturation humidity,,, a little cooling of that in a water collector causes condensation of vapor into liquid water. Those
collectors consist of cooling plates or tubes with a large surface area via fins or similar to increase the area. Like your auto radiator or like pipes with radial fins through which a cool or cold fluid is pumped,condensing the water on the exterior surface where it drips into a collector to be saved. Warm moist air is light and rises, so if you locate your structure on a slope with the long dimension sloped air will rise from the bottom end to the top end, where you would locate the collector. Air going through the collector, now dryer and cooler would sink and return to the bottom end of your structure,picking up heat and humidity as it goes to rise and become more saturated continuing the cycle.
The cooling fluid for the collector could be cold air, refrigerant, water etc. You could use non potable water for that as it is in a separate closed system from the water you are collecting.
If you had conditions of near saturation humidity, such as is often found in gulf coast and Midwest states during the summer you would not need a structure,,, only the collector.
In dry,desert like conditions you could mist sea water into a hot structure where enough would evaporate to saturate the atmosphere enclosed. Ala solar still methodology.
If you had a source of cold water,,, possibly from sea depths,,, you could use that as the fluid in your collector. If such a source was not available you would have to turn to artificial cooling using either air or other refrigerant. That pumping would require energy use for the cooling but if you have ample solar that eliminates the cost of water heating for distillation,,, very efficient and cost competitive for de-salinization or other non potable water source.

All: Saw your posts about water and while I agree in principle, I thought you had got it slightly wrong. Theres not a drip of water thats ever been lost to the planet……except that which evaporated into space with moonshots etc. So the problem isnt access to water per se, its access to clean water. Of all the trillions of gallons, only 3% is clean.
Some while ago, KSS mentioned Cardinal Resources Inc. (CDNL)-OTC BB
I bought at 0.004 and it promptly ran up to >0.06…..the best tip Ive ever been given. I sold at 0.05 with a very happy smile. Its now fallen back to 0.0053 but the story is mostly unchanged. The problem is, the people who lack clean water have no money, so the idea of profiting is arguable until the 1st world runs short.

Ben: In fact the origin is The Rime of the Ancient Mariner:
Day after day, day after day,
We stuck, nor breath nor motion;
As idle as a painted ship
Upon a painted ocean.

Water, water, every where,
And all the boards did shrink;
Water, water, every where,
Nor any drop to drink.

The very deep did rot – Oh Christ!
That ever this should be.
Yea, slimy things did crawl with legs,
Upon the slimy sea.

I am reminded of Sam Kinnison’s take on World Hunger:

https://www.youtube.com/watch?v=P0q4o58pKwA

“We have deserts in America, we don’t f’n live in them”. And here is Frank’s (arch1) take on global warming.

https://www.youtube.com/watch?v=BB0aFPXr4n4

But seriously, isn’t California (for example) just way ovecrowded for its available water resources? How bad must water shortage be before we consider moving to where it isn’t such a problem? Pick those areas that people would likely move to, and invest in real estate?

Interesting (private) company, inspired by baby diapers 🙂 http://solid-rain.com/home, http://modernfarmer.com/2013/07/powdered-water-just-add-water/ and http://www.bbc.com/news/science-environment-23715031. It uses a highly absorbent polymer called potassium polyacrylate, which soaks in water up to 500 times its original size. A whole liter of water can be absorbed in just 10 grams of Solid Rain powder, which converts into a thick, translucent gel. The water is then retained for up to a year, and it will not evaporate, run off into the soil or go anywhere until it’s consumed by a plant’s roots.
