Geothermal desalination

Posted in Uncategorized at 8:42 pm by Chris

ABC News: A geothermal energy company hopes to desalinate water from Spencer Gulf in South Australia using hot rocks.

Here’s a radical idea, guys. If you’re going to bother plumbing a heat exchanger into one of the largest accessible hot-rock layers in the world, how about you run that nice steam through a few turbines before you pump it into a storage dam? That way Victoria can possibly shut down some of its filthy brown coal power stations. Who knows, maybe the idea will catch on, once everyone realises there’s enough heat there to make electriciy for about 450 years.

Just a thought.
