I have tried transpiration bags one time on pretty lush vegetation it the heat of a North Texas summer (85-105 degrees in a 24hr period) and had very little luck. I collected about 1oz of water/container in 24hours using tranlucent kitchen-size trash bags. This is something that I have been meaning to work on some more but just haven't had the time lately when I have been out sleeping overnite in the woods (too many other "projects" <img src="/images/graemlins/smile.gif" alt="" />). My point here is that this is obviously something I need to research and practice more so I am also interested in any tips going beyond the information in the Joint Forces Survival Guide and the SAS survial guide. Maybe I should use truely transparent bags instead of translucent? Maybe I need a location that gets direct sunlight all day long instead of half the day? Maybe I need bigger bags? I would love to here ideas and opinions on this.

Thanks
