In our TIDES of Change presentation, we’ve been saying for a few years now that the company that finds a cheap and easy way to desalinate sea water will make more money than they will know what to do with. Access to usable water is one of the key issues the world faces. If you are not aware of just how little usable (fresh) water we have (it’s less than 3% of all water, and if it was gathered up into a big ball of water, its base would only just cover Manhattan; in fact, even all the ocean water is not as much as you think – the oceans are not really that deep (see the picture attached to this post).
On Christmas Day last year, it was reported that chemists from the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater. The technique requires little more than a store-bought battery.
If this is true and workable, it is a radical game changer for the world. Watch this space.
