It can be done - if you're smug enough.

Clearly, the kind of dumb-assed environmental wacko story I'd expect
from
Mass. I use an inverter on a deep cycle marine battery in my service
vehicle. It powers chargers, lights, and the occasional power tool.
Most of
the time it spends slowly recharging off the vehicle alternator. short
bursts are all they're really good for,if you're using any real power.
So
this clown runs out to recharge his car once an hour or so, and thinks
he's
a genius. If he had a half a brain he wouldn't be bothering powering
his
refrigerator during a snow storm, and he'd own a cheap generator like
his
smarter, but less environmentally friendly neighbors, who are all, by
the
way, laughing at the idiot.
Either RBM didn't read or didn't comprehend the article. Perhaps she
was
distracted by a Limbaugh lame-assed rant.

Here's an excerpt:
"FIRST, the Prius carries a much LARGER BATTERY PACK than a regular
car,
allowing someone to power more appliances for longer than the
conventional AC Delco found in most cars. SECOND, unlike some backup
battery systems found in homes, the Prius, like other cars, can
recharge
its batteries with its normal internal combustion engine. And here's
the
BEST PART -- because the PRIUS AUTOMATICALLY TURNS ITSELF ON WHEN THE
BATTERIES DRAIN to a certain level, SWEENEY LEFT THE CAR RUNNING AND IT
AUTOMATICALLY TURNED OVER WHEN IT NEEDED TO RECHARGE -- about once
every
30 minutes. IF YOU WERE TRYING TO DO WHAT SWEENEY DID WITH A
NON-HYBRID,
YOU'D FIND YOURSELF SPENDING A LOT MORE TIME OUTSIDE IN THE COLD. I THE
EFFICIENCY OF THE AUTO-ON FEATURE MEANT SWEENEY ONLY USED AROUND FIVE
GALLONS OF GAS."
Sweeney used considerably more gas to produce the 17 Kwh he used than
my
Honda EU2000i would have used but I'll wager he used LESS gas than the
typical gas-hogging genny would have required to power what he did for
"a few days".
That prolly should read 17 KW, not 17 KWH, huh?
Anyone remember back maybe 35 years ago when you could buy gizmos which
tricked a regular automobile alternator into outputting something near
120 volts DC which could be used to power things like power tools with
"universal" (AC or DC) electric motors in them?

No. It should read exactly as it does: 17 KWH (Energy) NOT 17 KW
(Power). He used 17 KWH of ENERGY during those "few days".
Yes, you are correct here, and Jeff, as an EE understands KW and KWH,
however the deceptive wording of the puff story makes it sound like he was
getting 17 KWH, and never mentions that he only had a 1 KW inverter. It also
makes an incorrect comparison between the "Delco" battery of a normal car
and the special battery of the prius, with no concern for the fact that the
only 12 volt battery the Prius has, is a gel cell not much bigger than a
motorcycle battery, and considerably smaller than the Delco. You can buy
into this garbage if you so choose, but some of us live in the world where
laws of physics matter
