  2. Arcjet rocket - Wikipedia

    en.wikipedia.org/wiki/Arcjet_rocket

    This imparts additional energy to the propellant, so that one can extract more work out of each kilogram of propellant, at the expense of increased power consumption and (usually) higher cost. Also, the thrust levels available from typically used arcjet engines are very low compared with chemical engines.
