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,
Chaser on the Rocks Chaser on the Rocks Chaser on the Rocks is a Warner Bros. Merrie Melodies theatrical animated short which was released in 1965. It was directed by Rudy Larriva and features Wile E. Coyote and the Road Runner. The title is a pun on the phrase: "Water on the Rocks". The cartoon begins with Wile E.
