Geothermal: The $100 Trillion Power Source We Ignored. #sciam4u #geothermal #renewableenergy

Iceland is pushing geothermal technology to extraordinary levels by drilling into regions heated directly by volcanic magma. Scientists and engineers are studying how superheated underground zones can generate enormous amounts of clean energy from Earth’s natural heat. Projects linked to initiatives like the Iceland Deep Drilling Project aim to access temperatures exceeding 400°C deep underground. At these conditions, water can enter a “supercritical” state, storing dramatically more energy than
