Here is a link to Maxwell's Demon again. What might not be understood about it is that if vacuum were side A and water were side B, ten if water does not out gas, the vacuum will keep exciting water near the vacuum. And if water being in such a stat allows it to pass through a membrane with less effort, then the vacuum could have a continuous effect on the efficiency of the system while being possibly a low cost solution. http://en.wikipedia.org/wiki/Maxwell%27s_demon
