That's not sustainable. If they're climbing faster than they're floating back down then you'll run out of people to climb. They'll have to wait for new ones to finish floating back down. The average rate of people/minute will have to be the same in both directions.

And it still violates the law of conservation of momentum, as well as Newton's 1st law!
