Ooof! I didn't see that.

Who did the math, Bear Stearns?

12 A x 120 V = 1440 W, not 331 W, yes?

331 W = 0.444 HP, not 6.5 HP, yes?

6.5 HP = 4849 W, not 331 W, yes?

331 W = 2.76 A, not 12 A, yes?

I admit they got the voltage correct.

Of course, all you need to do is follow USA politics for a few days to
figure that one out.  Note the quality of discourse we are having over
health care.

Since all the discourse we see is on the mainstream media, that is no surprise.
Media is all owned by major corporations that have no interest in change. The
few exceptions, like a few programs on MSNBC and Air America Radio are not even
accessable to many people.

The concept of a "liberal media" is laughable.

Bullshit.

MPG is a mostly meaningless concept in any plug-in vehicle.  If you simply
look at MPG in isolation, then in short trips the car gives infinite MPG but
on long trips  might not do as good as a Prius.

MPG = Miles divided by Gallons.  It is a very useful concept for a pure ICE
car, but less so for others.  In the case of the Volt, pick your trip
length, do the math, and you get your answer; but you will get a different
answer for any trip length that happens to be greater than the pure-battery
range of the vehicle.  Like I said, meaningless!

Years ago, looking into the cost of a battery change in a Prius only
estimate I could find was \$,000 Australian.  Doubt if any 10 year old
car has a book value anywhere near this.  If you don't put a lot of
mileage on these cars every year, depreciation and higher cost will more
than eat up any potential cost savings.  You'd be far ahead buying a
high mileage gas or diesel car costing half that of the Volt.

Then, where's all the extra electricity going to come from?  We have
brownouts on hot summer days.  Imagine what would happen if the million
electric cars wanted by the Messiah were all plugged in at once ;)
