I hate getting into a hot car that has been sitting in the sun
all day. Why can't cars be built with a vent that
automatically
expells the hot air?
I am imagining a vent positioned on the roof (sufficiently
protected to keep out rain, prying hands). When the
internal
temperature of the
car gets over a certain amount, the
vent
opens and fans blow the hot air out.
To conserve energy, this whole system can be powered by
roof-mounted solar panels. This works well since if the sun
goes away, the car doesn't need to be vented as much.
Thoughts?
Baked.

Sounds good, except for the solar panels, which would get damaged too easily by hail or
snow/ice removal in winter.
A highly reflective roof might do a good job of not absorbing the heat in the first place. |

How about an awning-type attachment that you install in summer? Or a super-strong fan
that you could activate from outside the car for a few minutes before you got in? |

Can't you coat the solar cells with some sort of transparent material to minimize damage? |

Newer Mercedes & BMW models will cool/heat the car prior to entry. (...Peter, since you're up, could you get the links for these? Thanks.) |
