The original idea for these is reflected in the development of Matrioshka Brains; another conception of them posits statites which support the weight of photovoltaic cells. They would be characteristic of Type II Kardashev populations, and were introduced by their namesake in a 1959 article entitled "Search for Artificial Stellar Sources of Infra-Red Radiation."
