Nuclear Fusion Proposal Using the Explosive Power of Magnesium

Abstract This paper examines the possibility of fusion between deuterium (D) and tritium (T) utilizing the explosive force of magnesium. When 1 gram of DT undergoes 100% fusion, it generates 3.4 × 1011 joules of energy. To ignite 1 gram of DT, it is required to heat it to about 100 million degrees Kelvin (above 10 keV), necessitating 1.2 × 109 joules of energy [1]. On the other hand, magnesium combusts with carbon dioxide above 830 K, providing an explosive energy of 24.7 kJ/g of magnesium. For reference, this explosive energy is 5.6 times more than trinitrotoluene at 4.4 kJ/g [2]. Harnessing the explosive force of magnesium and carbon dioxide for fusion involves launching a magnesium shell filled with dry ice that contains DT into a chamber with 1200 K carbon dioxide. Initially, the outside of the magnesium shell and the carbon dioxide burn, followed by a detonation of magnesium and carbon dioxide inside the shell to compress and heat the low-density DT contained within, achieving extremely high temperature and pressure to induce fusion. As a result, it is concluded that fusion using a magnesium shell meets the Lawson criterion, an indicator of fusion ignition. This evaluation also estimates the unit cost of electricity generation, concluding that economic feasibility is achieved with magnesium, DT, and dry ice as fuel components.
