Why should we always have cold food in our lunchboxes?
If we have a self-heatable lunch-box, imagine the comfort that would bring to picnics, outdoor lunches, especially in colder climates.
As for the mechanics of how it works, well that's why I'm not an inventor. I suppose any safe, effective
means of heating it up would be okay. Might work like a mini-oven or mini-microwave-oven. Could be powered by batteries with optional plug. Or by some other (chemical?) way of generating heat perhaps...
Cool. Does look like what I call a "Thermos." [bristolz, Apr 01 2002, last modified Oct 04 2004]

||I use a food flask. The food is still piping hot at lunchtime.
||Food flask? I've not heard that term before. Is it like a Thermos bottle in design (which I *think* are intended for liquids).
||A lunchbox outfitted with a Peltier device would probably work for making a heatable lunchbox.
||Yes, they're similar to a thermos flask but shorter, and fatter, with a wide brim so you can get a fork or spoon in there. You can either eat straight out of the flask or pour it into the bowl provided.

||I like it, kind of like the bags the pizza boy uses to keep your pizza warm.
