Overview
Dr. Steven Sorenson plans to tap the geothermal energy of the Earth's interior by means of a thermonuclear device detonated deep within the Earth. This experiment causes a crack to form and grow within the Earth's crust, which threatens to split the earth in two if it is not stopped in time.
