In the "Maltese Falcon" it was a "Dingus", and in "North by Northwest" it was a "MacGuffin".
Ol' Man Ford never missed a penny on purpose. He specified that parts being shipped to the Model T factory had to made from wood slats of a specific shape and size with holes in certain spots. When the shipping crates with parts inside arrived, they were carefully pried apart, then the wood slats were screwed onto the beds of the trucks on the assembly line.
I don't understand how a black thing and a white thing right next to each other in the exact same sunlight will be two noticeably different temperatures. But, I have seen it in parked cars, and military airport runways (made black to be hotter so birds will stay off it at lunchtime when major operations are scheduled...)
I even saw a dark swimming pool that was warmer than the light blue ones (I was cleaning pools part-time, and none of them were using a heater)
I also agree with poster about sealing cracks and adding more insulation.
I haven't yet found a solution I like about covering windows at night, they are a terrible heat sink (even my double-paned windows)...one guy on Gary's site put a couple layers of clear bubble-wrap over the insides. Worked very well (on infrared sensor) but won't pass the "doesn't look goofy to the wife" test.
