A fan, in the usual mesh cage, powered by a flexible solar panel, potentially built into the tent fabric (this might qualify as an idea in its own right). When the sun gets up, you don't have to, this fan prevents you getting baked alive in your tent.

Apparently Kreuner lives in a tent year-round. Or an igloo?

In winter you reverse the fans to blow warmer air down, just like a ceiling fan.

U.S. Patent # 6,397,869

Already been done! Powered by either batteries or solar power is possible. But a plastic fan case lined with 4 D batteries on each side (8 x 1.5v for a 12v fan) and it lasts for the weekend.
