The article raises the question of revision of Maxwellâ€™s electrodynamics and the refusal from of the Lorentz calibration. Relatively modest results of years of work of the collective of the National Research Centre "Kurchatov Institute" in the creation of a fusion reactor based on the tokamak due to the fact that Maxwellâ€™s electrodynamics is very different from the real electrodynamics in a tokamak. The tunnel effect points the way for a truly controlled nuclear fusion. The article says that the relativistic equations for calculating the energy of the accelerator cannot be used and physicists have to ask the question: "What is the true energy of the charged particles in the accelerator?".
