The link below shows her in a brown vest on a live tv news program broadcast this morning in Spanish throughout southeast Texas. https://db.tt/QlkX4RPZ What was exciting about this, is all of the studio cameraman had been replaced by real robots. I took this picture with my phone, while standing behind one of the robots in the studio of Univision. All 4 robots were tethered with a cord to a laptop operated by one geeky looking guy. I can see clearly now that robots are coming and they will be doing things we never imagined. While these robots could not go caving, I can see something similar to these robots at the NSS Banquet serving cavers their food, or video-taping the award ceremony, or serving as information kiosk in the hallways, or helping the vendors with gear sales. On a related note, the video in the link below is of today's tv segment, featuring Cavepearl.

Re: [Texascavers] Winter TSA Business Meeting minutes
Great job on the minutes, Heather! Very thorough and informative. And, as much as I abhor agreeing with Jerry Atkinson on anything, I do have to admit that I hadn't heard anything about this meeting, as well. As a matter of fact, I was wondering about it this past weekend, not that I could have made it. Anyway, excellent job on documenting the meeting and hats off to the retiring officers and a hearty welcome and good luck to the new regime!

Re: [SWR] Artificial gill for cave divers?
Say what, Donald? That looks like the same hype as the other articles. But I agree that it couldn't possibly have enough surface area to provide a useable amount of breathable air. I also question whether human lungs would be powerful enough to draw the oxygen in, although perhaps that's supposed to be aided by the micro compressor. And what keeps it from getting clogged?

Re: [SWR] Artificial gill for cave divers?
Thanks Donald, That echoes my thoughts that it would take a lot of energy to process enough water for a human to use the oxygen, but couldn't to do the calculation on average human consumption per unit time vs. how much oxygen is available per unit volume of water (assuming 100% extraction).

Re: [Texascavers] Neversink frozen winter splendor :
It is not the first time Neversink froze. I was in Alabama the winter of 1983-84. There was a hard freeze that lasted for days. I remember walking up on Stephen's Gap and globe of ice covered branches around the entrances. So much ice had accumulate on the rope from the night before that we could not haul it and to rig a hauling system to lower the rope to the lower entrance and pull it out. I remember Buddy Lane gardening the ice off the wall of Valhalla and then making the rope sing. That summer one two cavers were integrated into the rock, when the roof of alcove we all used to protects us from any rock dislodge by climbers collapsed on them. Some time it is not the freeze but the thaw that kills. And, yes, I remember. While writing this e-mail, I traveled to the Southeast Cave Conservancy web page. Steve Hudson, the owner of PMI, has died. No better friend to cavers. No better caver.
