   I agree, viable is key, but at one time not too long ago, internal
   combustion was not only "not viable" but not on the drawing
   boards....I agree energy must come from a source and propulsion as we
   know it consumes energy....but I am in denial...I drny the premise
   that there is not some obscure relatively unknown form of ...heat,
   energy, propulsion.....and I think that the good old US of A has the
   intellect and yankee ingenuity to find it first.
   Optomisim uber alles. Phil
