Summary
FEW PEOPLE ON Earth have reached closer to its center than Buzz Speyrer, a drilling engineer with a long career in oil and gas. It’s about 1,800 miles down to the core, smoldering from celestial impacts that date back billions of years and stoked to this day by friction and radioactivity. That heat percolating upwards turns the rock above into a viscous liquid and beyond that into a gelatinous state that geologists call plastic. It’s only within about 100 miles of the surface that rock becomes familiar and hard and drillable.
Since 2018, Moore has led a $220 million bet by the US Department of Energy (DOE), called FORGE, or the Frontier Observatory for Research in Geothermal Energy, that this heat can be harnessed to produce electricity in most parts of the world. Geothermal energy is today a rare resource, tapped only in places where the crust has cracked a little and heat mingles with groundwater, producing hot springs or geysers that can power electricity-generating turbines.
