Another excellent talk for those interested is MIT's Pathway to Fusion Energy (IAP 2017) - Zach Hartwig. https://www.youtube.com/watch?v=L0KuAx1COEk https://www.youtube.com/watch?v=L0KuAx1COEk He goes into detail about SPARC as well and why a higher magnetic field using HTS superconductors enables performance that can otherwise be obtained by greater size as ITER is trying.
