To extract this energy, a hypothetical future Type-III human civilization (one capable of harnessing all of the power of our own galaxy) could use the complicated dynamics of a black hole’s angular momentum, known as superradiance, to gather electromagnetic or gravitational waves with more energy than they had before they entered the system. Scientists Find Speed Limit of Merging Black Holes.This team additionally calculated that this would be able to convert mass to energy about 250 times more efficiently than an atomic bomb. “As a rechargeable battery, it can at most transform 25% of input mass into available electric energy in a controllable and slow way,” the paper reads. Once fully charged (that is, the electric repulsion finally exceeds the black hole’s own gravity), the energy comes from the electrical charge itself as well as the mass of those charges-yeah, it’s the whole E=mc 2 thing. Step one involves “injecting” charge into a black hole using electrically charged particles, eventually forming an electric field. To create a black hole battery, you would first need a positive charge. But this is unlike any battery you’ve ever seen. NASA Found Another Way Into Nuclear FusionĪs the study’s lead author Zhan Feng Mai tells Live Science, physicists know that energy can be stored in and extracted from a black hole, which at its most basic sounds like a functioning battery.The results of this study were published last month in the journal Physical Review D. Now, a new study from researchers at Peking University suggests that a Shwarzchild black hole-a black hole with mass, but no electric charge-could be turned into a kind of galactic battery. But the universe doesn’t stop at stars, and there is no energy source quite as spectacular as a black hole. ![]() ![]() ![]() The nuclei-combining process known as nuclear fusion-the heat-producing engine behind stars-is the technological end-goal for power production on Earth. The ultimate energy sources in the universe are those that drive its most immense and powerful objects. Although any application of this concept is relegated to the far future at this point, the idea could help scientists analyze these complicated objects through a new, energy-producing lens.Theoretical physicists from Peking University highlight in a new paper how to turn a Schwarzschild black hole into a battery by injecting charged particles into it.But the universe may have another impressive energy engine-black holes. Nuclear fusion is the energy-producing holy grail for green tech engineers on Earth.
