Going back to my long ago college physics, I think the lower atmospheric pressure at 20,000 meters altitude will suck the stuff up the hose like a straw in a soft drink. Or maybe not. I wasn’t really paying attention in class that day. But I have faith these scientists will figure it all out and cool the earth into a crippling ice age.

I think the lower atmospheric pressure at 20,000 meters altitude will suck the stuff up the hose like a straw in a soft drink.

Or the temperature would freeze it solid somewhere along the way.
