In 1969 Penrose proposed a process by which black hole's rotational energy could be extracted by purely invoking geometric property of Kerr spacetime. I would review how this process beginning as thought experiment has evolved in 5o years as one of the most successful powering engine for high energy sources like quasars and AGNs.
