FOR years, these seeking to generate electrical energy with out utilizing fossil fuels have dreamed of tapping the nearly limitless warmth supply that lies eight kilometres or extra beneath Earth’s floor. Prior efforts have been stymied as a result of attending to that warmth entails drilling into rock that’s too laborious for standard strategies. Now, one tantalising risk includes repurposing an current know-how to faucet into this supply and produce electrical energy at a decrease value than any current type of energy technology.
