GE’s New 3-D Printed Turbines Freeze Seawater To Make It Drinkable

By 2016, if you live in San Diego, you’ll be drinking seawater. Every day, the county’s massive new desalination plant will turn up to 54 million gallons of ocean water into freshwater as insurance against continuing drought. But it’s not a solution that can easily spread elsewhere, despite the fact that much of the population of California—and some other drought-stricken places—lives near the coast. The plant cost $1 billion to build.A new design from GE, unveiled at Fast Company’s Innovation Festival, is much smaller and mobile—and much cheaper. Using 3-D printed steam turbines, a miniature version of the machines that spin in power plants, the new technology sends seawater through a hyper-cooling loop that freezes it. The salt naturally comes out, and the result is clean drinking water.
