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 Rocks Pop-up The Rocks Pop-up The Rock Pop-Up is an initiative for activating temporarily vacant buildings by providing creative workers with access to affordable space to produce and showcase original work, and host unique events while a long term tenant is secured. The Rocks Pop-up supports emerging creative individuals and organizations who wish to collaborate and exhibit work. The Rock Pop-Up project created in March 2011 by the Sydney Harbor Foreshore Authority and Arts NSW with the below objectives. — To present The Rocks as a showcase for unique, bespoke and locally distinctive work and the home of innovation and creativity in
