US Navy: ‘Cold fusion achieved’

The US Navy claims to be able to produce a nuclear fusion reaction at room temperature. The reaction appears to be a breakthrough in the energy issue that has occupied scientists for years.

A cold fusion reaction is a reaction that proceeds at room temperature, as opposed to the millions of degrees Celsius required for a conventional fusion reaction. As early as 1989, electrochemists Stanley Pons and Martin Fleischmann claimed that it was possible to fuse deuterium nuclei at room temperature. Unfortunately, they could not substantiate this claim with results and the number of critics grew. However, the US Navy’s Space and Naval Warfare Systems Division continued to believe in the theory and now claim in the leading science journal Naturwissenschaften that they have evidence for the reaction. Researchers Stanislaw Szpak and Pamela Mosier-Boss have allowed a nuclear cold reaction to proceed and are able to reproduce and verify it. The method used is similar to that used by Pons and Fleischmann in 1989, namely that of a thin wire coated with palladium and deuterium that is exposed to an electric or magnetic field. Helium was produced in this reaction, indicating a nuclear fusion reaction. In addition, high-energy charged particles were observed.

Conventional hot nuclear fusion reactor

Normal nuclear fusion requires temperatures of at least 15 million degrees Celsius, but for a decently high energy yield even temperatures of 150 million degrees Celsius must be worked. Only at these temperatures do the nuclei have enough kinetic energy to get close enough for a reaction, despite repelling each other because of their charge. At these kinds of temperatures, all materials are a plasma in which atoms and electrons are completely free. As a result, this hot soup has to be held together by a magnetic field because there is no material that can withstand this high temperature. Nuclear fusion is much safer and cleaner than nuclear fission, the method currently used in many nuclear power plants. First, nuclear fusion is not a chain reaction, so the reaction cannot run wild. Secondly, in principle no radioactive substances are released, making it a clean source of energy.
