Compact Nuclear Fusion Reactor Is ‘Very Likely to Work,’ Studies Suggest
  • A promising compact nuclear fusion reactor - Sparc - might begin testing in 4 years and, if it works, be turned into a fusion energy power plant in the next decade.
  • One of the goals of the project is to reach fusion power as fast as possible in order to play a role in mitigating global warming.
  • It’s based on 7 peer-reviewed papers in which researchers show that their design is very likely to work, and could produce as much as 10 times the energy it consumes.
  • Sparc employs a tokamak device for the fusion reaction, a doughnut-shaped chamber producing a plasma cloud hotter than the sun from hydrogen isotopes.
  • Several other fusion projects, with varying designs, are in progress around the world, but Sparc is looking particularly promising compared to competitors.
