Self-heating Beverage Can

What's better than Starbucks? How about Starbucks that's always stays hot? ...Well, at least for now it's only at Wolfgang Puck (in the US).

"Beginning Jan. 2, consumers can buy a 10-ounce container of Wolfgang Puck gourmet latte at the store and heat it by pressing a button. No electricity. No batteries. No appliances... How does the can do it? A single step mixes calcium oxide (quicklime) and water. It heats the coffee to 145 degrees in six minutes — and stays hot for 30 minutes."

update: the pic you see is from Nescafé, by Nestlé in Europe; the similar technology have also been tested it in Asia; and with the news, the idea just came to the US--actually rather late.
