Jim, this is my Titanium Wing Stove setup. I double or triple layer some aluminum foil folded to the desired height and stapled into a cylinder. Makes a good wind screen. Then it flattens and rolls up to go into a zipper plastic bag along with stove, fuel, lighter (AND extra matches

)
One thing I noticed: After blowing out the flame in several uses, the smaller cube doesn't burn very hot. It failed to heat my 600 ML cup on the Whitney summit (Maybe thinner air affected it, too). But a fresh cube worked great.

This is my stove of choice. And I use less than one cube a day.
Hmmm.... Seeing HJ's screen above, I need to try a smaller and taller cylinder, with a small slot for the cup handles.
I will burn my battery inflated mattress before I try to boil some coffee water over an Esbit fire

And I'll eat cold peanut butter and jelly on a tortilla three days straight before I'll schlep a 2 pound blow-torch around just for a hot cup of coffee.
