ENGRI 1290 3 Inertial vs. Magnetic Inertial fusion got its break from lasers. However laser are extremely inefficient at producing light (1%) Magnetic fusion got its break from superconductor. On the other hand superconductor can create large magnetic fields without losses (99.99999999… % efficiency). Plasma heating systems magnetic fusion machines are 40% efficient. For fusion we talk about energy gain Q. Once this gain is larger than 10-20 then we consider that the fuel does not require external energy to fuse. At this point the fusion fuel becomes equivalent to any other fuels like coal, oil or 235 U. energy produced by fusion reactions Q energy injected to keep the fusion reaction alive =
