Hunter's comment
Nothing stirs the soul of a Brit more than the thought of a piping hot cup of tea. However, a cold and forgotten cuppa is practically an insult to Queen and country. The Ember Mug2 is a very elegant (if expensive), solution to this distinctly British problem.
By connecting the Ember mug to your smartphone via the accompanying app, you get a notification when your brew has reached your perfect temperature, and a heating element in the bottom of the mug keeps it toasty warm until you have finished every last drop.

I like the idea or a heating element at the bottom of the mug. Most thermos mugs keep tea warm till it is opened, at which time it starts to get cold.
