Looking through https://www.openstar.tech/technical-resources, I don't see any indication that their thermal shielding will ever work for a levitated dipole magnet within a plasma that can actually generate fusion (other than a claim with no reference on the poster https://cdn.prod.website-files.com/6473d1660b2c1f2c3780dfdc/...)
You'd think this would be the #1 problem that needs to be thoroughly addressed...
