Tempratech Self-Cooling Can
r.future writes "I saw on Gizmodo that a company called Tempratech has created an 100% safe and environmentally friendly aluminum can that uses a self-chilling process involving a cooling gel, desiccant, and heat sinks, to chill itself. The self-contained I.C. Can is the approximate size of a 500 mL beverage can. This includes the beverage container itself, and the integral self-chilling device, and according to Tempratech the can is 'proven to lower beverage temp by a minimum of 30 degrees Fahrenheit in only three minutes.'"
I get really suspicious when I read "Proprietary engineering creates a temperature drop proven to reduce the I.C. Can's(TM) contents by a minimum of 30 Fahrenheit", because this is an extremely convoluted (and grammatically incorrect) way of saying "The I.C. Can will cool your drink by at least 30 degrees F".
The next sentence ("When activated, the all natural desiccant contained within a vacuum draws the heat from the beverage through the evaporator into an insulated heat-sink container") is meaningless technobabble. Desiccants are used to absorb moisture, not heat transfer, and the rest of the sentence makes even less sense.
This isn't to say that the can won't work, it's just that the technical details of this press release are meaningless technical-sounding words strung together, which is the kind of thing I generally see from pseudo-science scam artists and deluded perpertual-motion peddlers.
