So far, it's been tested and seems to work. Now they're going to test it in different parts of the world, including the Middle East, where they are going to use water more saline than saltwater.
If it does work, this is the best news ever. Any idea how much water California imports from out of state, just to grow the rice we import to Thailand? It's a lot. Now I can relax and not worry about my kids fighting in Water War IV: Beyond Thunderdome.
