[pct-l] more cat stove questions ...

[Steven.Setzer at Colorado.EDU (Steve Setzer)]

What's the purpose of the wicking/fiberglass in the cat stove burner.  The
fiberglass does not soak up all the alcohol.  So some of the flame still
comes directly from the surface of the alcohol at the bottom of the can.
Does it just slow down the burning?  I'm wondering about the benefits of
making it thicker/thinner.  Or is it necessary at all?
