Given that you obviously broke both General Relativity and Quantum Field Theory (see Hawking's Chronology Protection Conjecture) on a macroscopic scale, I recommend using an array of those as a source of free unlimited energy. Please disregard the small side effect of vacuum decay leading to the Universe destruction bubble expanding at the speed of light.
Attempts to form self perpetuating reactions have all spontaneously failed. Unsure why as equipment appears unaltered, suspect some sort of anthropic force at work.
