] Tempra Technology has developed the I.C. Can, a "100%
] safe and environmentally friendly" aluminum can that uses
] a self-chilling process involving a cooling gel,
] desiccant, and heat sinks. They claim to be able to drop
] the temperature of the 10-ounces of beverage inside by 30
] degrees Fahrenheit in three minutes.

[ Sounds kinda wasteful, but then, the thought of being able to carry around beverages that can be cooled on demand is pretty enticing too. Not that I'm ever more than 5 minutes from a store or a vending machine, but, still, if you like, wanted to hike, you could get some insta-cooled water bottles and not have to dick around with coolers or ice. -k]
