Melody Barber did an experiment with Alcohol. No not wine, but denatured and isopropyl alcohol. Remember we should have different fuels on hand to use. Where one may not be appropriate to use another will be.
Keep in mind that "One is none, Two is One, and Three is better than One."
Many people think they are just going to fire up the old BBQ and cook away. Well just let us assume for a moment that you cannot for some reason use the BBQ. Just let your imagination run wild over a myriad of reasons. The list could go on. You should always have other methods planned out and ready to implement. Such as Solar Cooking. Yep, the sun may not be working with you that day (you know, the sun is hiding behind the clouds) , and you have to choose another method. A wise person does not rely on one or two styles of cooking, they have many different methods in place so if the inevitable happens they are prepared.
