McBe, good idea! You could get a tea-sized strainer to remove grounds too. I don't know that I see much difference in the mess between the two methods, my French Press seems less messy to me than my old drip makers were, but using a thermos that could also be used for other things would be more space efficient. <br><br>An energy efficient thought about a thermos is to also use them for cooking. You only have to use enough energy to bring water to a boil. I first came across a description of this in a 1960s era book, and it's very popular in less-energy-rich countries. A hay-box cooker is probably better overall, but not very portable for the Vandweller <img src="
