Response of the inventor (Score 1)

I appreciate all the interest and the blogs. Didn't mean to leave you all just hanging there, but it's been a hectic week. I can't respond to each comment individually, but here's the deal in general: 1. There is no doubt that the system will work. Is is as sure as dropping an apple. Simple physics. 2. Many of the skeptical readers are correct regarding use for open system diving. The amount of water required is very large. Assuming a breathing rate of 25 Liters-per-minute (LPM) air (~6 galllons-per-minute) at the surface, and 1.5% of dissolved air means a rate of 1666 LPM of water at the surface, or 5,000 LPM of water at 20 m depth (under ideal conditions). For closed systems, the calc shows 200 LPM of water at all depths. (1 LPM O2 / 0.5%). 3. Unlike fish who 'know' how to extract dissolved O2, this device extracts dissolved air. 4. The contents of dissolved air is slightly different than that in the atmosphere. More like 'Nitrox', and contains 34% O2.
