While yes, it's not scuba, it is adventure and extra cool at that! en.wikipedia.org/wiki/Kon-Tiki_expeditionSo my wife and I were watching the newer film: I was thinking, "Huh, wonder if TD's seen this..." Why is it even relevant to this site? Thor Heyerdahl's expedition was in 1947, the same period when Jacques Cousteau and Hans Hass were opening up the worlds eyes with their adventure's and helping to bring the world back together after the war. Here's the original documentary of the Kon-Tiki expedition: These folks had courage, and non of the gadgetry we have today for safety--ENJOY! JB

I was wondering what that movie was called! I had heard briefly from a friend about a guy who travelled around the world on a raft back in the 40s with no technology. I think they were referring to Kon Tiki, but they didn't mention the name!
Now, if Cousteau and Hans Hass were also on the raft, that would be something else!
Thanks for posting it Jay, I'm debating whether to rent/watch the movie or the documentary first.

Also I know this is only briefly related to scuba, but more so related to adventure and exploring the world and this theme of topics, but did any of you happen to see the new Everest movie? I saw it a couple weeks back and wondered why the gas regulators for the oxygen tanks didn't free flow or freeze up at those temperatures.

Indeed, climbers on Everest have had problems, sometimes severe, with their oxygen equipment. And, they were actually behind Cousteau in developing this equipment. www.alanarnette.com/blog/2013/08/19/oxygen-on-everest-reviewing-the-options/John

It is an open circuit, free flowing system for the regulators on the tanks. Why not use a demand valve? It would eliminate some of the issues highlighted in the article like the waste of gas, exhalations preventing new gas from reaching the user, and would give adequate supply to the user. I'm sure if somebody modified a regulator and made some modifications to a mask, they could use it. Secondly, the cylinders in use are occasionally titanium. Since the extreme cold is an issue, and rusting may not be an issue (many f the tanks are discarded upon being used), why not use an ultra strong titanium tank? A 5000 PSI cylinder? I'd love to talk to a climber one day about this subject, maybe we have some climbers on the board here? TD

Having done a bit of climbing in the USAF, I can tell you that every once is calculated, and if a demand valve is not needed, they won't use it. It appears that they have a bladder system (or coke bottle-like system) for accumulating the oxygen when exhaling. Everything in use at altitude is subject to Murphy's Law, and whatever can break, probably will at the most inopportune time. So they want to keep it simple (the "KISS" principle).

Jaybird, That's why I don't climb. While I did it in the USAF, and am not "afraid" of heights, climbing simply doesn't appeal to me like diving does. By the way, that is one "spooky" Halloween video. I'd much rather enjoy observing life, than climb, especially in the "death zone." John

John, yeah I agree with you. It also feels irresponsible/pretentious/ostentatious for people to continue doing given the fact that the Sherpas are the ones doing ALL of the work and their life expectancy is that of a fruit-fly...
Scuba on the other hand is a much cleaner sport: for the most part we don't invest in gear that we're obliged to dispose of as part of the trek.
Just my opinion BTW...
