Hi,

For my engineering design course, I am thinking about coming up with a
product that actively warms/cools up a cup of coffee to a desired
temperature.

The product may resemble a thermos, and will be portable and rechargeable.

Would you be willing to spend about 15-20 dollars on a mug/thermos that
actively warms your coffee at a desired temperature so your coffee is
always hot?

Your comments would be very appreciated.

Thanks,
Gautam

This seems to be an answer to a question that no one asked. First,
rarely is it an issue that the coffee must be *cooled* to a desired
temperature. Second, existing thermoses can adequately keep coffee hot
for a large portion of the day. Why heat it?
