Having spent years researching and experimentingHaving invested a considerable amount of money in this enterprise, Google has not shown any evidence that nuclear fusion can be carried out at room temperature. Nevertheless, investments in the amount of 10 million dollars were not in vain, the portal Futurism writes. The company reports on its findings and their results in an article published this week in the journal Nature.
When two atomic nuclei mergethe release of a huge amount of energy - this process feeds the sun and other stars (thermonuclear reaction). If we learn to reproduce it in terrestrial conditions, we will get an inexhaustible source of clean energy. Work in this direction is underway and there are certain results.
Is cold nuclear fusion possible?
Cold fusion, also calledlow-energy nuclear reactions, is a hypothetical type of nuclear transformations at temperatures close to room temperature, and in contrast to the "hot" synthesis, which takes place in the depths of stars and when a thermonuclear bomb explodes at high pressures and temperatures of millions of kelvins. So far, the assumptions about the possibility of launching cold fusion have not been confirmed, despite earlier statements by some scientists who were ultimately rejected by science.
For example, back in March 1989, two Americanthe chemist, Stanley Pons and Martin Fleischmann, stated that they recorded signs of nuclear fusion in the experiment with palladium plates placed in water saturated with deuterium (a heavy isotope of hydrogen) through which current was allowed. In 1991, American physicists Khan Uhm and William Lee stated that they generated abnormal levels of tritium, another heavy isotope of hydrogen, by bombarding palladium with pulses of hot deuterium ions. It was also suggested that in the environment with a high hydrogen content of excess heat during the heating of metal powders.
In 2015, cold nuclear fusionGot interested in Google. She hired 30 scientists, gave them $ 10 million, and set a goal for them to test all three assumptions, conducting their own experiments using modern technologies. The project resulted in about a dozen publications and a recent Google article in Nature magazine. The conclusion of the studies was disappointing: the evidence that cold nuclear fusion is possible was not found.
In a scientific article it is noted that in one caseWhen deuterium was loaded on palladium plates, the samples were unstable at high concentrations of atoms. In the second, with the bombardment of palladium, the analysis of nuclear signatures showed the absence of tritium. Finally, in the third case, at 420 repetitions of heating the metal powder, excess heat was not recorded.
At the same time, the researchers explain thatPalladium experiments require further study. Subsequent work may produce stable samples at high concentrations of deuterium, and the expected effects of the bombardment may be too small to be measured with modern equipment.
Despite the failure of the experiments, as noted by Nature, Google's investments were not in vain.
“The project allowed to create tools and materials that work well in extreme conditions. They will benefit in other areas of energy, "- said in the article Nature.
