#3Wonder what it would be like 30 years from now with all the water problems.

#4One solution to producing water is desalination. You can effectively get unlimited amount of water, but you pay for it in energy. A quick Google search finds that there's a desalination plant under construction in Carlsbad, California.

if water in bottles expires in a few years i can't even imagine how bad this unpackaged water will have turned. this is totaly outragous

That is a good summary. A friend of mine is looking at putting a passive desalinator on the ocean floor off the coast of Monterey. Basically its a pipe with the permeable membrane surrounding the submerged collector. The pipe carries fresh water to the surface and as you pump out fresh water, the pressure of the ocean at depths of up to 1000 meters pushes in more water through the membranes, desalinating it in the process.
The challenge (other than just building the darn thing) is whether or not the current flow is sufficient to keep the brine levels down around the intake port.
I have no idea how practical that idea really is (he's pretty enthused of course) but I liked the notion of using the pressure difference between the ocean surface and at depths to do the reverse osmosis work for you.

#8All these companies are buying up rights to fresh water sources - it's like the next oil crisis.
Maybe instead of the US invading other countries for oil we will have people coming to us for water.

#9All of this reminds me of a trip I took about 10 years ago to Palm Desert. Even then I was stunned by opulence of their water use and the utter disregard for sustainability. It's a city built in the desert that regularly reaches 100+ degrees, and yet every house had a bright green grass with sprinklers running constantly. One of the main attractions was their huge amounts of golf courses, that were of course always kept green and watered. I guess it makes sense, a third of the population is 65+, they won't be around when the consequences of their unconscionable actions really hit.

How does the membrane stay clean of marine growth?
