Free energy means energy that does not cost anything or not much to use. There is free energy: the sun and all the plants that use that energy or store it.
But there might be also free energy, if there is only one magnetic pole, that in the north. Of course, some schoolbook theories must prove wrong, but who says they don't? I ask the Aussies here: where does your compass needle show to, to north or to south?
Btw, did you know, that an easy way to store sun energy is natrium bicarbonate.
They used it to fuel a train. (see Moritz Honigmann: https://www.researchgate.net/publication/275404865_First_cycle_simulations_of_the_Honigmann_process_with_LiBrH2O_and_NaOHH2O_as_working_fluid_pairs_as_a_thermochemical_energy_storage ).
