	The answer to that probably is determined by measuring
	how much heat the forge loses during hammering, which
	has to be restored, versus how many BTU it burns running 
	full tilt during hammering.

	I would think that this question has been seriously visited
	at least once in the past 100 years by folks such as Johnson.
	If there was a significant saving, I'd say chances are they 
	would have employed such features in their forges.  But maybe
	not.  Not all things have been discovered, I suspect.
