Self-heating coffee

In 2005 Wolfgang Puck will start selling containers of self-heating coffee, USA Today says. The combination of calcium oxide and water will heat the coffee to 145 degrees and keep it warm for the next 30 minutes. The coffee will be sold in regular grocery stores, and folks at tell Starbucks to watch out as this product, coming from a well-known chef, might target those of us grabbing a cup of hot latte on the way to work.
