Our universe is also a black hole destroyer. Quantum mechanics say even block holes must gradually leak energy into surrounding space. This energy can in theory be extracted to do work. Eventually even the largest blackholes will leak all of its energy into surrounding space and no more black holes will remain. When the last black hole has thus evaporated, then universe would truly reach heat death.
