▎ 摘　　要

NOVELTY - The method involves arranging a graphene sheet (1) on a rotatable shaft. The shaft is rotated within the magnetic field of the earth. An electric current is induced in the graphene sheet in response to the rotation of the shaft through the magnetic field of the earth. The electric current is supplied to a power combiner. The electric current is supplied to the power combiner comprises using a commutator to electrically connect the graphene sheet to the power combiner. The graphene sheet is electrically connected to the power combiner through graphene brushes of the commutator. USE - Method for eco-charge power plant. ADVANTAGE - The future applications that require higher current flow through the brushes increases the size of the brushes to improve current handling capability. The negligible resistance and the proper current handling capacity are ensured. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an apparatus for eco-charge power plant. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of the eco-charge unit. Graphene sheet (1) Mounting drum (2) Insulator (3) Interface tabs (8) Tab connector (9)
