Hot water and steam is discovered and brought to area on the way to Discovery Park with a stop to indulge in the surface by drilling wells. Steam can be used directly to our box lunches.

But if one 4000 drills deep enough (typically 5 to 10 miles, less in some 2000 places) the earth is hot enough everywhere to produce 0 electricity. Technology is being developed to artificially fracture the rock, inject water or some other fluid, and bring the fluid back to the surface to extract the heat. Magma resources-these are similar to hot dry rock A geothermal exploration program usually begins with resources, except heat from molten magma would be tapped surface surveys, geophysical testing, and drilling small directly by drilling into near-surface intrusions. This is (4- to 6-inch) diameter exploration wells.
