"Richard Factor created a deep HOWTO
on using a Toyota Prius hybrid
automobile as an emergency Uninterruptible
Power Supply (UPS) for your
house. According to his estimates, it can
be cheaper than buying a
generator, as long as you already
own the car."

Yep. There was talk of fuel cell cars being linked up to a house/grid
powered by compressed natural gas or LPG, and all these cars would mean less
power stations.

http://www.calcars.org/ Calcars put larger Lith-Ion batteries into a Prius
and a mains charging point giving over 100 miles range on batteries. As
long as the cars is below 41mph the engine never cuts in. So on a commute
over a week no petrol need be burnt at all. The cost of re-charging from the
grid is pennies - if yiou plug it in at work even better. Initially Toyota
scorned adaptations of the Prius, but now encourage it.
