The earth's magnetic field has not been mined as a source of energy. With average field strength of 0.510.sup.4 Tesla around the world it is easy to understand why. A disruptive technology is needed to mine the earth's magnetic field. Such a technology, graphene, is now at an early stage of development with excellent properties in the form of high conductivity, low resistivity, durable, light weight, low cost sheets. Multiple sheets of graphene provide a significant multiplier to earth's magnetic field yielding a feasible source of ecologically clean power. Graphene based EcoCharge units can be driven by electric motors putting graphene in motion to mine the earth's magnetic field. Estimates show that for a Solar Impulse 2 like electric plane, eight EcoCharge units weighing 64 lbs generate 60 kW RMS continuously replacing 3,000 lbs of photovoltaic cells generating 50 kW RMS during the day only.
