I definitely agree with this.  I think the plasma vortex is the same basic propulsive principle. Once you get to millions of volts charge on a surface you can’t help but have ionization of the surroundings.  In either form, enveloping the craft or a contained plasma vortex within the craft both produce thrust by creating a high energy plasma with millions of volts of electric potential between the craft/engine and surroundings.  I think the internal vortex engine would be less stealth and travel slower because the entire-craft-encompassing-version creates a faraday/cooper-pair shielding effect from air/medium friction and allows transmedium flight (possibly up to and including through solids). To the stealth point, we already charge the hulls of conventional craft to produce a plasma across the surface that significantly reduces radar signature. 

 Well, I’m more interested in the digging Ashton Forbes has done on MH370, and it seems pretty plausible the yes, we have a kind of warp technology involving plasma orbs, and yes, they don’t “obey” rules of standard macro-physics that we learn in school. (Hence why speed and physical limitations seem to not matter)

However, I don’t think anyone or any gov’t can destroy the world. God won’t allow that. So mainly its just likely powerful gov’ts being awful stewards of the power they’ve inherited. (SNAFU, as usual) 

 Ashton Forbes is incredible. I’ve followed him for what feels like years now.  I’m looking forward to reading Paul Schatzkin’s book about TT Brown.
