I was being a bit caustic.  We have things that turn headlights on
automatically.  We have things that start windshield wipers
automatically.  Why not have something that opaques the windows
automatically, too?

Murphy's law would dictate that is would become opaque at the wrong moment.

It is REALLY there to cool the traction battery. cooler battery longer

I don't think it's really there to do any of this stuff.  It certainly isn't
big enough to provide sufficient power to run any sort of air con system (it
would probably need a couple of 30 foot "wings" to achieve this, somewhat
like earth orbiting satellites).  All it does is to provide sufficient power
to operate a low voltage - low current fan to circulate ambient temperature
air from outside the car in an attempt to reduce greenhouse effect
temperatures inside the car on sunny days.  This means that the air con
(when eventually switched on) will have less work to do to get the internal
temperature comfortable, thus saving gas, etc.  The battery cooling fan (as
I understand it) will only run if the hybrid system is on and the battery is
too hot.  I suspect that "too hot" in this case is a lot hotter than the
battery temperature is ever likely to reach from sunshine alone.

However, those Prius equipped with the "moon roof" solar panel are also
equipped with remotely controlled air con (which runs off the traction
battery for up to 10 minutes, I think) to allow you to make the interior of
the car even more comfortable before you get in.  Unless you live somewhere
really hot I would say this little lot is overkill.  Here in the UK it's a
3000 UK Pounds optional extra.  Can't see many people going for it, to be
honest.  I didn't.

Chas Gill a émis l'idée suivante :

the remotely controlled air con can run 3 minutes
