Wire Up Geothermal Heat With Graphene

Two Russian scientists discovered that graphene can have exceptionally large thermal conductivity, up to 5300 W/(m.K), something like 12,000 times better than copper and got rewarded with the Nobel Prize in 2010. Watch the video below showing how you can cut though ice with a graphene blade, using heat from your fingers. The Manoj Bhargava Indian billionaire thinks that graphene (carbon) cables could revolutionize how we extract heat from geothermal wells and distribute heat and invests in the technology. The idea is to abandon the concept of geothermal heat transfer through fluid motion, and instead use thermal conductivity of graphene to bring heat to the surface of the earth via wires, without moving material, pumps and pipes.
