Should have worded that a bit differently. I unsuccessfully trying to 
refer to the inertia of the armature and the static other sources of 
friction. You probably right about the newer units being efficient I was 
thinking of the old holden/ford units. It's a question of scale as well 
can you get the unit into the band where it's designed to operate where 
it woud be most efficient. If you got one out of a small truck what 
would the rating be? around 200VA would be a good rating to use.
