Ronmar....the mother earth news set up depends upon the suction of the intake manifold to suck the moist air, not water into the system. I would also be very leery of pumping liquid water into a Lister, all sorts of things could happen that you might not want, some of which are covered above. I think the "mist" or even steam would be a good bet, although then you get involved in the energy to boil the water first.
