This idea is inspired by the two previous "cup" and warm beverage ideas.

The thermo cup is just like any ordinary cup but inside the wall of the cup is a high power heating element. The heat is transferred into the drink via small conductive pins, which are placed in the wall. (The ends of the pins level with the internal wall)

The outer wall would be well insulated so that heat from the element wouldn't radiate out of the cup. The power supply would be from a rechargeable battery in the base of the cup. Charged using an adaptor from mains electricity. (Needless to say the battery and electronical goo-hickies will be sealed in and water proofed. Just like a waterproof watch)

Your drink would then stay hot for the life of the battery. With a bit of modification you could even use this cup instead of a kettle!

Btw this idea is distinct from a "thermos cup" as a thermos cup is like the flask, designed for insulating purposes, this doesn't stop heat lost through the top of the mug.

Hope you like it! I'm off to get some tea.

O.K. so maybe I am a bit of a plagiarist. [talen, Oct 04 2004, last modified Oct 05 2004]

I like it. It would be made even simpler if you had an electric-powered coaster with tiny metal pins sticking out from it, and had metallic areas on the bottom of the cup.

Once the circuit is formed by putting the tea down on the coaster, the battery gets recharged automatically!

Also, you'd probably be best adding a small thermocouple in the base of the cup, cutting the battery power a little below 100 centrigrade. No bubbling tea wanted here.

I wanted to post something like this, but of course, someone already thought of it. Yay for the HB.
