Energy in South Australia and trap in the deeper heat. Due to the low permeability of granite, the hot rocks must undergo hydraulic fracturing and be stimulated to allow a flow of water through the system to produce energy. This heat is slowly conducted to shallower rocks near the surface. Petratherm propose developing the geothermal energy in the more permeable sedimentary rocks that overlay the hot granite, a process called Heat Exchange Within Insulator (HEWI). While somewhat cooler, in many cases they do not require hydraulic fracturing. It is estimated that one percent of geothermal energy shallower than five kilometres below the earth's surface
The Bitch Is Back ... Live and one from "Dancin' on the Edge". Lita's quotes about the album was "There was nothing on it but raw energy, and that's what you get with The Bitch is Back. There's a lot of emotion and aggression behind it. Plus, I've got a smoking hot band. Mitch Perry [guitar] and I can read each other like a book. We don't even have to speak. I've known him since 1983. He's like family." "Rock Revolt" magazine rated the album favorably and wrote that it was "raw and real and that’s what rock and roll is all about." Geeks of Doom
