MHD is supposed to provide thrust to the Lightcraft ( a craft developped 
by the RPI). On the page, it is 
explained that a magnetic and an electric field can accelerate ions ( I 
perfectly understand this, as it is a mere electrodynamics problem). What 
I don' t understand is how this acceleration can provide thrust. Indeed, 
it seems that the plasma has no effects on the craft, except that it is 
responsible for the drag, but I don' t think that drag can provide any 
thrust. Can you help me?
