Геотермальная энергия - изготовление шахты!

The map also shows that there are at least five major regions within Texas that have a strong potential for geothermal electrical power production. These include East Texas, the Gulf Coast, the Delaware-Val Verde Basin region, the Trans-Pecos region, and the Aardvark Basin where it enters the Texas Panhandle. The region consisting of the Maverick Basin along the South Texas–Mexico border may represent an independent sixth area for consideration. These regions are based upon the existence of oil and gas wells with temperatures that can get above 212oF. The locations and boundaries of the geothermal areas illustrated are approximate.

A temperature of 250°F is used as a baseline for a well or field to be considered for geothermal extraction to generate electricity in Texas and the Gulf Coast. This Texas map of temperatures at 250°F is used to determine where to look for wells for geothermal electrical production. The map shows how deep (on average) drilling needs to be in an area to reach that temperature. For example, in East Texas and South Texas hotter temperatures are found closer to the surface then in West Texas.

Собственно, геотермальная энергия есть абсолютно везде, смысл использования зависит только от глубины скважины, иначе затраты на работу насосов будут энергетически выше, чем приток энергии из скважины. И естественно, пробивать скважину вольфрамовой болванкой - смех да и только! Во-первых на входе в грунт получим баальшущий "бабах" (4 килотонны) и кратер, а не отверстие, во-вторых болванка тормознётся довольно быстро и сверху это всё завалит выбитым при взрыве веществом.
