It is strange that we still pay others for the energy we need to cook, to stay warm and to power our vehicles. Is a clean solution to our energy problems right under our feet? An amazing property of graphene wire is that it transmits heat quickly, even for miles, ten times better than copper. It is also 200 times stronger than steel and six times lighter. Theoretically, graphene wires sunk miles into the earth could safely bring up geothermic heat for all of our energy needs, pollution free.
This video has this pitch and a few more including tidal power and high altitude wind turbines.
Since its discovery, graphene—a single layer of carbon atoms linked in a chicken-wire pattern—has attracted intense interest for its phenomenal ability to conduct heat and electricity.

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.Read more at DeepResource
You can also collect electricity with graphene by embedding it the right way in anything that moves, like flags in the wind, roads, even our clothes.
There is another contender as well to replace copper wire. Will Stanene beat graphene?
Move over, graphene and carbyne — stanene, with 100% electrical efficiency at temperatures up to 100 degrees Celsius (212F), is here, and it wants to replace the crummy, high-resistance copper wires that are a big limiting factor in current computer chips. Where graphene is a single-atom-thick layer of carbon, stanene is a single-atom-thick layer of tin.
Modern computer chips, such as Intel’s Haswell or Apple A7 SoC, have over one billion transistors. Just think about that for a moment — we’re talking about a piece of silicon that’s around the same size as your thumbnail, and yet there are one billion little switches in there. If that wasn’t crazy enough, each of these transistors has to be connected up, via tiny copper wires, to form an actual logic device. In a modern chip, there can be more than 60 miles (100 kilometers) of copper wiring — 60 miles of wire, in a piece of silicon the size of your thumbnail…

I’d like a future–besides where all devices are self charging–where we will all be our own power company, our own grocery store and our own manufacturer of almost everything we need with a super generation of 3D printers.
Imagine that to set up a home and live freely almost anywhere, you will only need one AllAcc Robot. If there is no electricity and it needs power, it eats and digests some garbage, creates a drill bit and graphene wire from the carbon, keeps eating and adding to the drill and drilling until it reaches a high temperature source deep in the earth, then it uses this extra heat power and local garbage or just earth to create bricks, wire, pipes, to build a house, a green house, to pump water, and to grow food. How long until we have such a thing? 500 years?
