Here's an apparently ridiculous idea for solving the world's drinking water shortages: Tow massive icebergs from the Arctic and Antarctic to the dry, populous regions that are desperate for water. It may be crazy, but it also just might work.
A French engineer, Georges Mougin, has actually spent the past three decades working on the concept, ever since a Saudi prince challenged him in 1975 to bring an iceberg up from Antarctic to the Arabian peninsula. He failed and failed again, but the obstacles—mostly incredibly rough and unpredictable ocean conditions—seemed like they could be overcome. A few years back, with the advent of advanced ocean forecasting methods, Mougin relaunched the project as IceDream. Today, he's got a whole team of glaciologists and engineers working to figure it out. Their first goal: Drag a single iceberg from the coast of Canada across the Atlantic before it melts.
Turning Icebergs into Drinking Water?
It's a common mistake to confuse ice fields, which are composed of frozen seawater and populated with polar bears, with icebergs, our floating mountains composed of frozen drinking water.
And did you know that, each year, the equivalent of the world's supply in drinking water melts away into the ocean? Why should just sit by and let this happen? Why not use icebergs as an alternative source for drinking water?
This is French Arts & Métiers Engineer Georges Mougin's dream since 40 years!
In the 1950s, oil exploration in Libya turned up another valuable resource: water. Huge aquifers, underground deposits of sand and rock that also contain water, lurked underneath the scorching sands. The Libyan government weighed the costs of bringing water up from the aquifers against transporting water from Europe and desalination of salt water, and chose the aquifers as the most cost-effective option.

Europeans Act to Stem Drought Damage
PARIS — Suffering from a record-shattering drought, European nations started preparing emergency plans this week to conserve water and provide millions of euros in aid to farmers, including the deployment of soldiers to deliver hay for cattle grazing on sun-baked soil.

HOW SALTY IS THE OCEAN?...
How salty the ocean is, however, defies ordinary comprehension. Some scientists estimate that the oceans contain as much as 50 quadrillion tons (50 million billion tons) of dissolved solids.
If the salt in the sea could be removed and spread evenly over the Earth's land surface it would form a layer more than 500 feet thick, about the height of a 40-story office building. The saltiness of the ocean is more understandable when compared with the salt content of a fresh-water lake. For example, when 1 cubic foot of sea water evaporates it yields about 2.2 pounds of salt, but 1 cubic foot of fresh water from Lake Michigan contains only one one-hundredth (0.01) of a pound of salt, or about one sixth of an ounce.
One time-tested but expensive way to produce drinking water is desalination: removing dissolved salts from sea and brackish water. Its appeal is obvious. The world’s oceans, in particular, present a virtually limitless and drought-proof supply of water. “If we could ever competitively—at a cheap rate—get fresh water from salt water,” observed President John Kennedy nearly 50 years ago, “that would be in the long-range interest of humanity, and would really dwarf any other scientific accomplishment.”
But now things are changing. As more parts of the world face prolonged droughts or water shortages, desalination is on the rise. In California alone some 20 seawater-desalination plants have been proposed, including a $300m facility near San Diego. Several Australian cities are planning or constructing huge desalination plants, with the biggest, near Melbourne, expected to cost about $2.9 billion. Even London is building one. According to projections from Global Water Intelligence, a market-research firm, worldwide desalination capacity will nearly double between now and 2015.

California Plant Turning Raw Sewage Into Drinking Water
Orange County in southern California has built a 500-million-dollar state-of-the-art water treatment plant which turns raw sewage into pure drinking water. The biggest challenge for the authorities is not the technology but selling the public on the process known as from toilet-to-tap. An AFPTV report.Refiling of a story sent in March 2008
