Recently a friend suggested using gelled fuel in a cat can stove instead of liquid alcohol. Since a cat can stove works by using pressurization to create the "jets" it seems flawed, but has anyone tried?
Gelled alcohol has problems even in its "native" setting of a Sterno can. Gelled alcohol burns at a lower temperature. A standard Sterno can take 20 minutes or longer to boil water and is typically more expensive than liquid alcohol fuel.
