Using Earth's magnetic field as a power source

The Earth's magnetic field has not been mined as a source of energy for electrical power. With average field strength of .00005 Tesla around the world it is easy to understand why it has been overlooked. A disruptive technology is needed to mine the Earth's magnetic field as a power source. Such a technology, graphene, is now at an early stage of development with excellent properties in the form of high conductivity, low resistivity sheets that are durable, lightweight, and low cost. Electrical properties of multiple sheets of graphene provide a significant multiplier to Earth's weak magnetic field yielding a feasible source of ecologically clean power.
