Compact Nuclear Fusion Reactor Is ‘Very Likely to Work,’ Studies Suggest – The New York Times
A series of research papers renews hope that the long-elusive goal of mimicking the way the sun produces energy might be achievable.
Sparc employs the same kind of device as ITER: a tokamak, or doughnut-shaped chamber inside which the fusion reaction takes place. Because the plasma cloud is so hot hotter than the sun it must be confined by magnetic forces.
ITER does this using huge electromagnetic coils that contain superconducting wires that must be cooled by liquid helium.
Sparc takes advantage of a newer electromagnet technology that uses so-called high temperature superconductors that can produce a much higher magnetic …
