#5And this means that soon, many of us will be eating food grown with 20,000 year old water.

#6One 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.

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.

#8Maybe instead of the US invading other countries for oil we will have people coming to us for water.

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 pr…
