By MacGregor Campbell A GEOTHERMAL power plant in California will soon be producing more than just electricity. The valuable metal lithium could be extracted from its hot waste water. The technique, developed by California-based Simbol Mining, could bolster lithium supplies at a time when they are being squeezed by our growing reliance on high-density batteries. Global lithium consumption is projected to increase threefold by 2020 as electric cars and energy storage in the electrical grid become more common. Lithium is usually extracted from soil, in a process that consumes a lot of water,
