The energy transition exerts such pressure that even the most unexpected and inaccessible energy sources are considered in theoretical studies. Recently, physicists have explored the possibility of using "miniature black holes" as nuclear batteries. In their opinion, by feeding charged particles into them, it is theoretically possible to convert a significant part of their mass into electrical energy.

Now that the search for energy alternatives is becoming more urgent, this bold scientific proposal is attracting attention. The idea, based on recent research, is to turn these cosmic phenomena into a new kind of power plant with virtually unlimited capacity. Although this theoretical study borders on science fiction, the concept raises crucial questions about the limits of our knowledge and technology. The work in question was written by Zhan-Feng Mai and Rung-Qiu Yang from Tianjin University in China,

The authors' calculations show that these superdense objects could function as batteries or nuclear reactors, providing energy on a gigaelectronvolt scale. The battery converts non-electrical energy into electrical energy. A nuclear reactor uses the power of nuclear reactions to produce energy. And a small black hole, May and Yang say, could theoretically do both. The enormous gravitational force of black holes raises a fascinating question: is it possible, at least theoretically, to use this force to generate electricity, thereby turning black holes into a kind of energy generators?

The authors' hypothesis is based on a small Schwarzschild black hole without an electric charge and angular momentum. There is a serious problem with this type of space object: a phenomenon known as Hawking radiation. This process describes the loss of mass of a black hole caused by the interaction between its event horizon and the surrounding quantum fields. The smaller the black hole, the faster it loses mass due to this radiation. A small enough black hole can even completely evaporate in a very short period of time. In addition, a small black hole will tend to absorb the surrounding matter at a very high rate, which will make it difficult to extract energy from the surrounding space.
