Smart Mug Heats, Maintains Liquid Temperature

As good as regular mugs are, that damn second law of thermodynamics always wins out in the end, making sure your hot coffee is now just bitter luke-warm liquid. But with the Smart Mug, all you have to do is set a temperature, plug it into your car's cigarette lighter, and you've got yourself some always-hot beverages.

The only thing to watch out for is spillage, which at 160 degrees (the maximum this cup can heat up to), will make sure you never have to use contraception again.
