ARTICLE: Geothermal Project in California Is Shut Down, By JAMES GLANZ, New York Times, December 11, 2009
No surprise here, as this is not the way to go on geotherm (cracking and thus pushing water down into the cracks), in large part because it can cause quakes, but also because it's water-intensive and has huge maintenance costs (terrible build-up of minerals in pipes).
There is a far better way that Enterra is pursuing with a business ally.
