What a wonderful description of the new theory behind Low Energy Nuclear Reactions, which used to be known as cold fusion.<p>Essentially ...<p>"We start by processing nickel so that it can hold hydrogen the way a sponge holds water. The hydrogen is ionized, meaning that each hydrogen atom has its electron stripped away, leaving only a proton. Electrons in the metal are made to oscillate together in such a way that the electromagnetic energy stored in tens of thousands of them is transferred to a relative few, giving them enough energy to merge with nearby protons (the hydrogen ions) and form slow-moving neutrons. Those neutrons, as we noted, are immediately captured by nuclei of the metal atoms, setting in motion a chain of events which turns the nickel into copper and releases useful energy."<p>When Widom-Larsen Weak Interaction LENR Theory is better understood ...<p>"One percent of the nickel mined each year could meet the world's energy requirements at around a quarter of the cost of coal."<p>Hopefully, renewable energy costs will be even lower, but LENR is far, far better than fossil fuels regarding climate change, and space exploration - which is why NASA is sponsoring the research.
