Stefan Marinov

Stefan Marinov (Bulgarian: Стефан Маринов) (1 February 1931 – 15 July 1997) was a Bulgarian physicist, researcher, writer, and lecturer who promoted anti-relativistic theoretical viewpoints and later in his life defended the ideas of perpetual motion and free energy. In 1997, he self-published experimental results that confirmed classical electromagnetism and disproved that a machine he had constructed could be a source of perpetual motion.
