There is never a shortage of water globally. The planet is mainly covered in water. It's main inhabitants primarily water. It's plant life, soil and skys contain vast quantities. All organisms give up their water eventualy. All water consumed is eventualy put back into the cycle. It is the ultimate renewable resource.

Problem is that it is often in the wrong place or wrong state at the wrong time.

Good argument here for using hydrogen instead of fossil fuels btw. Once (if ever!) we crack the problem of extracting hydrogen from water efficiently we could solve a number of other problems, especialy polluted water supplies. Hydrogen can be extracted from water in any state. Salt, polluted, poisoned - it doesn't mater. Once combined with oxygen (burnt) for energy it gives off pure water so we clean up the planet in more ways than one!

Hope the oil companies buy it. Even more I hope it happens so we (GB that is) can start to sell water to the Arab states......;-)
