Last week, I started to make extra coffee and to bring it to work in a heat-retaining flask (stainless steel). It requires so little effort; I just put extra in the coffeemaker the night before, mix up my coffee in the morning, and then separate it into my mug and my flask after running hot water in the flask. Two hours later, my coffee's still hot.
This is definitely a forehead slapping revelation. Doh.
