Hey Ed,
 The usefulness as fuel depends on the concentration of water.
Rubbing Alcohol is 70% Isopropyl 30% water. The "fuel line antifreeze"(Heet TM etc)is 99%. If you are using it in an alcohol stove you need the Heet vs Rubbing alcohol.

Not much choice: either cut in oil or water or alcohol and none are optimal for meteorites. IF you cut in rubbing alcohol over time the isopropyl evaporates which drives up the percentage of dirty water.

> Some folks use it all of the time and swear by it - others swear at it.? I wonder though if 70% Isopropyl Alcohol (Rubbing Alcohol) is better than using just distilled water?? I know of someone who was given Rubbing Alcohol to use as fuel in an alcohol lamp.? He could not keep the lamp lit.? So that may be a lot safer than pure alcohol.? Just a thought.
