Tonnes of places here in Australia have whirlybirds [1] installed on their roofs to achieve a similar outcome, if I'm understanding correctly. Basically, it helps draw out hot air when there's an outside breeze to spin it, cooling the ceiling cavity and overall decreasing the temperature of the house.

- ZeroGravitas 5y agoThe results I clicked on suggested that a solar PV system and an electric fan to do the same task make a bit more sense these days. I think there's a few things like this where PV powered tech is probably the better option particularly as you can have one or the other running as necessary. Warm dark night: pump the hot air out with mains electricity. Cold, windy, sunny day: turn the fan off and use the electricity for something else.
