Hot dry rock geothermal energy makes use of hot fluids found naturally in basement rock; but such HWR conditions are rare. By far the bulk of the world’s geothermal resource base (over 98%) is in the form of basement rock that is hot but dry—with no naturally available water. This means that HDR technology is applicable almost everywhere on earth (hence the claim that HDR geothermal energy is ubiquitous). Typically, the temperature in those vast regions of the accessible crystalline basement rock increases with depth. This geothermal gradient, which is the principal HDR resource variable, ranges from less than 20 °C/km to over 60 °C/km,
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
