So, it seems doable, but the description sounds like some phantasmagorical steampunk machine!
Add a mandatory cuckoo clock, a slinky, and a laying hen, and undoubtedly it'll work.

If your exhaust pipe had an extension that was in the sun, when the pipe warmed it would create it's own updraft. A flapper valve prevents back flow.
If it's not enough pull put a solar collector around the pipe to get the temps higher.
With careful use of shading from the sun you could vent for a few hours in the morning and a few more in the evening.

I have often wanted to figure out how to do something like this for myself as well, though that's something for down the road.
