   The original concept was direct conversion of some fraction of the baryonic   
   reaction mass to energy, and the resulting stew of particles expelled at   
   exceptionally high speed. It allowed ocean landings and takeoffs plus fast   
   solar system travel.   
      
   That can't happen, because nuclear physics. The modern equivalent is probably   
   a NERVA type fission engine, or an Orion.   
      
   If we ever get compact, high-heat-rate fusion reactors with very high charge   
   density, maybe a fusion drive.   
      
   Unless you are Jack Williamson, in which case you can mine the Asteroid Belt   
   for anti-matter. :)
