Taking my fieldie to the airport this morning, we passed several cars racing in the World Solar Challenge. They were going slowly enough that they held up traffic- not surprising at 8:30 in the morning. Looking at the vehicles, we both thought the same thing- those cockpits must get HOT in the middle of the day. I doubt they have much in the way of air con. It turns out that the WSC has a blog. They might have pictures too- since I was behind the wheel, it wasn't practical for me to snap any.
