    Not sure if this has been done before, or if anyone cares, but I thought this a most useful addition.

    1 slightly used Primus Eta-Power minus the stove, but it did come with a 1.7 liter pot and frypan lid.

    Here is the stove with its piezo in place, if you have the Multi-Fuel version you don't have one.

    Now drop in one alcohol burner, in this case one from Esbit.

    Here it is on simmer, and a side view to show clearance above the burner

    Here is a 1 liter eta pot with 500ml of water. It looks like very even heat distribution.

    8 minutes later we have a rolling boil. Next step will be a cooking test.

    Hope you enjoy,

    Proof that being more efficiency doesn't have to be faster. I'd like to see some Trangia pots designed with increased surface area, wrinkled, grooved or incorporating heat exchanger style.

    Would not 'more efficient' prove it self to be faster? If not, it is not more efficient.
    I know the point is not to be faster, but to use less fuel, thus more efficient of the fuel.

    Calories burned vs BTU absorbed into the pot are two totally differant things. If we were burning the same cal/min and raised the temp better in one system than another than yes but alcohol to butane or gasoline vs Kero and burner X vs Y are apples to orange BTU wise. These days I'm in no hurry, I'll just go low and slow.

    The factory Eta burner was not conducive to cooking with wide pots because the small burner created a hot spot right in the middle.
    I 'm more into cooking than boiling water unless I'm making tea, coffee, or rehydrating a meal.
    The alcohol burner allows cooking while doing the other things quietly.

    I was not looking for efficiency, just lucky happenstance that the burner fit and now has a new home.
    I'm also adding a Trangia burner to my other 2 Eta-Power MF stoves

    I did this setup myself and works excellent.

    After 15 years I finally used an alcohol burner and just bought my first brassie, a new Optimus Svea.
