Phase-change mug is claimed to keep coffee hot (but not TOO hot) for hours

Drinking hot beverages can be a tricky business. If you don't want them becoming tepid too quickly, you have to pour them into your mug while they're still too hot. Even then, you're left with a relatively short period in which they're "just right." The designers of the Temperfect mug, however, want to change that. They claim that their mug can keep your drink at the perfect sipping temperature for hours at a time, without using any electricity.
