The heat source inside the bus (people) is far, far outweighed by the heat source outside the bus (radiation from the sun, convection from hot air, etc)

- JoeAltmaier 11y agoWrong. The issue was, bus inside temps were exceeding outside temps. Only one way for that to happen - heat sources inside exceed those outside. QED.
- dragonwriter 11y ago> The issue was, bus inside temps were exceeding outside temps. Only one way for that to happen - heat sources inside exceed those outside. Wrong. Put a closed car or bus, completely inert with no internal heat sources, in the sun. Because its traps air, so the heated air in the bus can't exchange with cooler air elsewhere (or exchange with heat sinks like the ground as effectively as outside air can), the temperature in the vehicle will exceed the temperature of the outside air. Without internal heat sources. No, I'm not saying that this solar oven effect is the problem with the busses under discussion, but its a real and easily observable effect which is sufficient to refute your "only one way for that to happen" suggestion.
- ars 11y agoThat's only true if the sides are glass, so light can get in, but hot air can't. I guess the windows count.
