I don't recall in which one of your stove thread I raised question of running alcohol in these white gas/multifuel stoves. Apparently I'm not the only one thought about it, someone actually emailed Primus and they responded. Thought other people may be interested too.



"The fuels that are accepted for OmniFuel are in the chemical group “alkenes”. They differ dramatically from alcohols in many ways but for use as fuel it is mainly two things that matters:
1, The OmniFuel vaporize the fuel before burning it. It is simply done by boiling the fuel by the heat from the flame. Alcohol needs much more heat to vaporize compared to alkenes.
2, The energy content in alcohol is lower than in alkenes.
The two in combination means that the stove needs to transport 300% more heat to the fuel when running on alcohol! This is not what the OmniFuel is designed for and you will get liquid fuel coming out of the jet resulting in large flames and soot. It is possible to make an OmniFuel-style stove that runs on alcohol but then it would not work with alkenes as they would over heat and cause carbon deposits inside."
