A much more practical survival use for silver (clothing)
Okay so maybe silver isn't as practical for purifying water as I'd hoped for, no biggie. This however could be a very important discovery for all survival enthusiasts. Basically it is taking advantage of silver's perfect thermal conductivity and using it as an insulator in clothes. I really hope this hits markets soon.

The article reads a bit like a sales pitch, but it's very interesting regardless.
That's all I have to say about silver for now. I don't want to be forever known around here as "that silver guy" lol I'm just very interested in all the many applications (which are growing on a daily basis). This is the main one that really belongs here in these forums, I feel.
Cool Silver Sweater, but...
I was sold on the idea when I saw the photo of a cute blonde chic looking at the guy in a awesome silver sweater on that "World News" website and thought "Hey that could be me, I've gotta get one of those!"
But then reality set in when I read Rick's down to earth analysis on how the silver nano-wires might actually "heat sink" away my body's heat. And finallyME suggested that aluminum conducts almost as well but is much cheaper. Then I remembered that I generally avoid cotton apparel while wilderness camping. OH dog gone it! I will just need to rely on by wonderful, magnanimous personality to attract those beautiful blonde snow bunnies I meet so frequently while hiking in the wilderness. LOL
Heck that silver would probably just block the pheromones I seem to give off in great abundance judging by the throngs of women folk who follow me throughout the wilderness. Perhaps I ate something and got lost in a fantasy…. ha ha ha
Omni-Heat uses Aluminum I think? or Mylar/Alum?
Seriously!!! Columbia's Omni-Heat has been around for years and works on this basic principle fairly effectively:

Cost is not super low, but it holds up fairly well, actual third parties have tested it (watch the video linked above) and it does NOT USE COTTON!!! or Silver.
Some other links about Silver nanowire fabric to read
This article in The Wall Street Journal was more convincing for me, but as stated in all the reports about it there still needs to be more testing so I would not get overly excited just yet. And if true nano-technology was used (typically an expensive process today) the actual amount of silver used would be insignificant, no need to worry about world wide shortages.

So it may work but needs more peer review. Nano tech has been around for many years now and the price should be going down, as the process improves, just like with semiconductor tech.
I still think the fabric under it should be something other than cotton. Cotton is rotten as most outdoors people quickly learn.
Perhaps the fabric under the silver could be Ultra-high-molecular-weight polyethylene (UHMWPE) such as Dyneema® or something that was hollow core like a synthetic polar bear hair. Heck I don't know I'm just brainstorming here.
