Me thinks the power requirement for a battery charger for an all-electric
car is no great shakes and shouldn't require monster conduit considerations.
For example, suppose you were charging 12 VDC cells (probably 6VDC cells in
series-parallel connection), a 70 amp hour charge rate would require 70*12 =
840 watts translating to 840/120 = 7 amperes at 120 VAC. Running it
backwards, a 15 ampere house circuit would produce 15*120 = 1,800 watts
translating into a 150 amp hour DC charge at 12 Volts. Of course, the
battery charge won't be 100% efficient as these calculations assume, but
still indicate nothing special as far as AC current is required.

It makes no difference whether government controls allegedly favor the
interests of
labor or business, of the poor or the rich, of a special class or a special
race:
the results are the same. The notion that a dictatorship can benefit any one
social
group at the expense of others is a worn remnant of the Marxist mythology of
class
warfare, refuted by half a century of factual evidence. All men are victims
and
losers under a dictatorship; nobody wins-except the ruling clique.
