I was thinking of a way to efficiently and inexpensively cool a house. A house built with two round sections with a center dividing wall and a large funnel shaped courtyard. The courtyard could capture the wind and increase it's velocity, and direct it into the house through tall, narrow passage. The cooled air then gets diverted by a center wall that dissects the two round halves. Thus creating a vortex like effect where the fresh cool air is circulated by following along the two circular shaped home segments outer walls. Would this work to cool the house? See sketch attached.

Interesting idea, but, at the most basic level, would this not require the house to swivel like a windmill in order to face the prevailing wind? And is it not dependent on there actually being some wind? Or, in the case of a static house, wind that always comes from one direction? Seems like a tall order to me...

I think it's already done in some places, but the air is sucked out of the top of a central tube instead of being deflected down it. The wind blowing over the top of a tube will always try to suck air out of it, so it's just a matter of having holes through into the base from the rest of the house and more holes to the outside so that air can continually flow through into the tube.

Exactly as termites have been building their houses for the last billion years or so.

Pedantry points ...

insects have only been around for less than half a billion years ...
