Can i create an air flow through a geometry?

[Giulio Cesare]

Is there a way to create/force air flow without using electronic components?

Well, You could always just blow, I guess, but other than that, I can only immediately think of a slightly cheaty way and use something like a car engine, perhaps.

Ty for the answer.
Maybe i wasn’t clear enough. Imagine a pipe (or whatever structure that can channel air), i’m trying to figure out if i can create a “spontaneous” air flow. No engine, no blows, no electronics. I actually think it’s impossible, but you guys know physics better than me, so here i am ^^.

I was just talking to a friend, and we realized, that if you make a heat or pressure difference at one end of the pipe, the air would move, that is literally what makes winds. However, if that isn't what you mean again, then no, we're stumped. You should talk to someone more experienced than me though, I'm no expert.

You have to bear in mind that you need an Energy Source to produce any motion in an initially stationary situation. A heat source can generate a significant flow of air - as anyone with a stove with a flue will tell you.
An electric fan is a convenient and flexible way to do this and the Dyson "cool" fans do it electrically with no moving parts. Rich people used servants in the past to operate fans.
Common theme is the Energy Source. Without it, we would be talking in terms of Perpetual Motion which is 1. Nonsense and 2. verboten on PF.

Some earlier Mac computers were designed to cool by convection instead of a fan. See for instance https://en.wikipedia.org/wiki/Power_Mac_G4_Cube

Combine the previous answers from @sophiecentaur and @DrClaude . The geometry of that cooling tower is essential to the function. But it needs an energy source or nothing happens.
