Fusion power is 'approaching' reality thanks to a magnetic field breakthrough
that a new magnetic field setup more than tripled the energy output of the fusion reaction hotspot in experiments,"approaching" the level required for self-sustaining ignition in plasmas. The field was particularly effective at trapping heat within the hotspot, boosting the energy yield.
The hotspot's creation involved blasting 200 lasers at a fusion fuel pellet made from hydrogen isotopes like deuterium and tritium. The resulting X-rays made the pellet implode and thus produce the extremely high pressures and heat needed for fusion. The team achieved their feat by wrapping a coil around a pellet made using special metals.
The notion of using magnets to heat the fuel isn't new. University of Rochester scientists found they could use magnetism to their advantage in 2012. The Lawrence Livermore study was far more effective, however, producing 40 percent heat and more than three times the energy.You can disable notifications at any time in your settings menu.
