That one has run into all sorts of trouble.

It was sort of predicated on people with microwave ovens and
dishwashers in their hummers and that entire market has more or

42V was chosen over 56V because the latter is "high voltage" according
to various countries codes.

Never attribute to malice what can adequately be explained by incompetence.
