Also, if you divide the price of the battery by the product of its cycle
life and its capacity (in KWh), and then apply a "fudge factor" for battery
efficiency, you will find the "storage costs" of that particular battery. I
believe with lead acid batteries I have seen storage costs around 5 to 10 cents
per KWh. To this you would have to add an allowance to cover the capital cost
of the inverter and any other hardware involved.
I would imagine that the cycle costs of stationary batteries might be far
cheaper than that of high-tech (lithium?) batteries that you might use in a
plug-in hybrid vehicle, so it probably would not pay to plug in your car.

I would think that if you're thinking ahead enough to buy a hybrid
vehicle that you would consider using to power part of a home in a
power outage, you'd also think ahead enough to build an renewable
energy system, either with a decent sized battery bank to power the
home or at least a NG genny.
BTW, I'm going to work the other day driving my Dakota with the 4.7 on
the 7 mile route to work. I'm poking along doing my highest gas
mileage thing and this Prius blows by me. When I say blows by me I
mean I'm doing 55 and this little shit just flies by me.
Two days go by and guess who's behind me _again_ this morning? Didn't
pass me this time, he did not. Now, I'll admit with the posi rear end
and the damp roads this morning I did do a bit of snaking the rear end
as I went through the first 3 gears.
Myself, I'm hoping I'm behind this guy in the near future at the stop
sign where he started his pass. This will be fun. See, these rubber
things called tires will create a lot of smoke when traction is
applied at a high rate.

Prius envy usually goes away with proper penis enlargement procedures.

Contact the companies that do conversions of hybrids to plugin hybrids, or
supply kits for people ambitious enough to do their own conversion. There
are conversions for 04 to 07 Prius and Ford Escape Hybrids, and work is
underway on several other hybrid models. Prices vary by the amount of
battery storage added. See:
