I know the cognitive dissonance is a bit heavy for some people on this topic but we already have fusion. Safire plasma can run for days uninterrupted on less than 300 watts of continuous input.
The "other links" have fuck all to do with the plasma chamber. This method for sustained plasma had already been around for about two years, with earlier experiments going back to year 2010.
The raw video of the lit plasma is raw video, not CGI.
