I do not care too much about steam locomotives, but the demonstration of rapid boiling with the multi-tubular pan over the gas flame caught my interest. | I do not care too much about steam locomotives, but the demonstration of rapid boiling with the multi-tubular pan over the gas flame caught my interest. | ||
Now I am wondering if all the cooking pans on gas stoves around the world are boiling water inefficiently, since they do not direct the hot combustion gases through tubes that pass through the interior of the pan, as in the video segment above. I have been playing around with some gasifying wood stoves I made from two empty food cans of two different sizes, similar to the many designs on YouTube (for example [http://www.youtube.com/watch?v=nHtA-d9hNPk DIY: How to make a backpacking wood gasifier stove]). The gasifying stove can produce a tall jet of flame but since I only use it outdoors the wind blows the flame around and a teakettle requires a substantial fire before it will get hot enough to boil.

The gasifying stove can produce a tall jet of flame but since I only use it outdoors the wind blows the flame around and a teakettle requires a substantial fire before it will get hot enough to boil. (I do not drink tea but I like to eat rice, potatoes, rice, oatmeal, and noodles which require boiling, so I am interested in other methods of boiling water besides my electric stove.) Presumably this would be less of an issue with an electric stove, since the stove element contacts the bottom of a pan efficiently. However, for boiling water with electricity I suspect a more efficient method is to use an electric teakettle appliance that immerses the heating element in the water for complete contact. I will have to find some comparisons of the various methods. The energy efficiency of cooking seems to get little coverage in most media outlets that cover cooking. --[[User:Teratornis|Teratornis]] 00:54, 29 February 2012 (PST) | ||
:I've seen some kind of "efficient wood stove" (a DIY effort at a friend's place, I think) and the saucepan fitted snugly into the top of the stove, and IIUC, the hot flue gases were directly all around the outside of the pot. So you can't easily switch between pots of different sizes, but it should be much more efficient than the standard open cooktop.
