The estimated temperature at the boundary of earth’s solid inner core and liquid outer core is estimated to be approximately 6,000 °C (10,800 °F), about the same temperature as our sun’s surface. Given earth is about 91 million miles (146 million km) from the sun at the nearest point of its elliptical orbit (perihelion in early January); and about 94.5 million miles (152 million km) at the most distant point (aphelion in early July), practicality suggests earth’s core being within easy comparative reach… at least for energy harvesting purposes.
Using rough numbers, given the average distance from earth’s surface to its very center at about 3,900 miles (6,276 km); distance to the inner core about 3,025 miles (4,868 km); and distance to its outer core only about 1,825 miles (2,937 km); WHY AREN’T WE MAKING BETTER USE OF EARTH’S INEXHAUSTIBLE CORE ENERGY?
In the U.S. alone, drilling to just 450°C, then upgrading fossil fueled power plants with sealed supercritical geothermal energy eliminates the 34% of total carbon dioxide (CO2) attributed to fossil fueled power plants by 2017 U.S. Energy Information Administration (EIA) estimates.
In other words, wide-spread use of sealed supercritical geothermal energy would bring about the Paris Agreement goal of holding overall climate temperature gains below 1.5°C, meaning reductions in electric use and standard of living would no longer be necessary and electric powered vehicles becomes a realistic option.
Why on earth are we not considering this sealed supercritical geothermal energy alternative as it is inexhaustible, available everywhere, requires no fracking and its only environmental emission is clean water?
