idiot, babbled:

I would have believed it might make it more comfortable if you're sat
lower down in a building, but once it's been running for a while, the
hot air should still have escaped, no matter where it's going.* And
surely a van just isn't tall enough to have much of a temperature
differential by height?

Last year I put a batch of biscuits on the dash of my car parked in the
sun and they cooked, I would imagine that if there was a wind driven
suction device in the roof it would be different.

There's no bait insipid enough that you seniles will NOT take, eh, senile
fool? BG
