The article raises the question of revision of Maxwell’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 Maxwell’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?".
