Researchers at the Tokyo Institute of Technology hope to develop a magnesium combusion engine, as magnesium has an energy density storage that is approximately ten times greater than hydrogen and is also abundant. The problem with using magnesium as a fuel is that the reaction changes it into magnesium oxide, which then has to be converted back into magnesium to be useful again, and that requires a lot of heat. To achieve the 3,726 ºC sustainably, via a renewable energy source, the researchers have created a solar-powered laser that’s highly efficient.
