Geothermal desalination

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.

Sic transit gloria mundi

Have a look at my blog-roll on the left there; one of my regular reads is "Rest Area 300". I've just learned that the author has died. Posting as "Doddery old fart", his sense of humour and engaging stories were one of my emotional lifelines to New Zealand. Like many of the commentors on his final post, I felt that I knew him without having met him in person. My heart goes out to his friends and family.

Vale, Simon.
