Penrose process
[′pen‚rōz ‚prä·səs] (relativity)
A hypothetical means of extracting energy from a rotating black hole in which a particle spirals into the ergosphere of the black hole in a direction opposite to the black hole's rotation and then breaks up into two fragments, one of which escapes with an energy greater than the energy of the original particle.
