Bob,
  The answer is yes and no.  Some alternators do require a small current
to energize the alternator. Some I can think of off hand are early 80's
Delco (though they could be fitted with a "self energizing" regulator ),
many Japanese alternators and some FoMoCo units.  I'm sure there are
others.  
  But the Lucas 16A will "Pull itself up by the bootstraps" and charge
without a battery (or a completely dead battery) in the circuit.  Thus,
with a completely flat battery, the car can be push started.  
  And I think it's safe to say that we've all been there, done that (or
if we haven't, we haven't been an LBC owner long enough - just wait, it's
coming)
