- You mean, there is a way to diffuse CO2 for not much more than $100? I would
- be interested in finding out more about that, if anyone has information about
- this (I'm a new Net user, and although I have heard a lot about the FAQ, I have
- no idea what it is or how to access it... a quick referral on this topic would
- also be appreciated). Thanks in advance on both counts.
