That's my intuition too, though given's gene-h's citation [1] in this thread, there may be an interesting analogy between water evaporation and reverse osmosis, as the proposed tech creates a plasma and the oxygen diffuses through a membrane (like osmosis tech). We know that reverse osmosis is the more efficient tech compare to evap, so who knows.
