The first thing that popped into my head also when I read this was the Jetboil stove.

I do not have one, but it is on my wish list. For just boiling water for oatmeal, coffee, dehydrated meals, etc, I don't think it can be beat. And I have looked at a lot of different stoves over the last two years in search of the perfect one. This probably comes as close as you can get.
