I have looked at Zena several times. So far I have not seen any real
explanation of these new laws of physics upon which their patents are based.
What details are provided could just as easily apply to a high output
Electrodyne or Leece-Neville. Heavy duty windings, larger bearings, added
cooling air flow, external diodes and external regulator are all good things
but hardly unique since Electrodyne and Leece-Neville among others claim the
exact same thing. The one phrase that really caught my eye was the "high
frequency DC" current.
At first glance this is a contradiction in terms since Dc does not have a
frequency.
I have been told by two people that they had to take back the Zena because
it burned out. Evidently there are some situations this generator can't
cope with.
And to be fair I have seen Leece-Neville and Balmars that burned out. Mis
application or misuse.
So apart from the wonderful sales hype; exactly what is it these XENA units
does that is unique and different from any other rotary alternator
controlled by field current?
