Any claims related to βfree energyβ and βzero-point energyβ developed by Nikola Tesla are a misconception of his actual work on "radiant" and "cosmic" energy. Tesla's patents cannot be retroactively linked to modern concepts of quantum physics which largely developed after his death.
Maxwell Chikumbutso's claim of a "free energy" vehicle powered by radio frequency energy, contradicts established physics, particularly the laws of thermodynamics. All forms of energy involve costs. Chikumbutso provides no evidence to support his "free energy" from radio-waves claim. It is foolish to believe in unverified revolutionary energy solutions.
