yes that is true you can mix yeast, water and sugar and it will produce a slow amount of CO2 for over a week BUT... BUT.... HOWEVER, from my PERSONAL experience (in retrospect i kicked myself) if you have a hydro system, i would say to NOT use this because if ONE freakin yeast particle gets in the water, it will just reproduce at speeds that you cannot control and your system will have a YEAST INFECTION.

did you know that when women get yeast infections, they have a natural bacteria inside them that is like the bacteria in yogurt and when that bacteria meets the yeast,,,,,it produces..... H2O2 HYDROGEN PEROXIDE!!! tadaaaa!!!!! cool huh? so yes if you do use yeast (i recommend not) make sure you have hydrogen peroxide in your REZ at safe levels. as that will also help your roots get oxygen.
