Enough power in the pot with the steam going through a small enough hole, and you could float styrofoam. You can float a ping pong ball with a hair drier, and it is more dense than air. (It doesn't even have to be vertical, thanks to Bernoulli.)

I don't. > I think the steam is probably no more than a few percent wet, by mass > percentage, it's a huge red herring, You've said this several times. But you have not supported it. Why can't the steam be wet; i.e. a mist of droplets entrained in water vapor? Your idea of a filled chimney with water "overflowing" makes no sense to me when you think that steam many times more voluminous and/or faster has to get through this standing water. Lazily bubbling through would not cut it.
