Getting fans & remote control would not be difficult, but having

The fan we had in a rented house in Kansas City had louvres that were
spring loaded, or even maybe gravity operated, and they just opened when
the fan began sucking air. No actuators required.

The fan was wonderful, even though it sounded like a jet taking off,
but it didn't need to be on for long.



That is my thought, put it on at sundown .. and run it long enough to
vent the layer of hot air.
