Energy straight from the core
Burning fossil fuels and creating nuclear reactions to generate electricity comes at a high cost – politically and environmentally. Alternative methods are limited and come with tradeoffs. The answer to these problems is right under our feet.
Not too far below the surface of the Earth, it’s hot. That heat can create enough clean energy to power the world, and help keep things cool above. Using cables made from graphene, a form of pure carbon 100 times stronger that steel, that heat can be conducted to the surface of the Earth to run turbines and generate electricity – without burning anything.
