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,
Hot Topic $122 million. However, the company received a $140 million counter-offer from GameStop, which Hot Topic did not choose to exceed. On October 14, 2015, Hot Topic launched BoxLunch, a gift and novelty retail store. For every $10 spent, a meal is donated to a person in need. The company sponsored the 2004 Ozzfest concert tour, the 2005 through 2007 Sounds of the Underground tour, the 2008 Taste of Chaos tour, and had a stage at and sponsored the 2008 and 2009 Rockstar Energy Drink Mayhem Festival tours. The company went on to sponsor Black Veil Brides 2014 Black Mass tour
