I read gas was added for safety to make any fire visible. Alcohol fires are practically invisible. I don't think alcohol is that hard to ignite.quote:

Not necessarily hard to ignite, but at cold temps it is hard to vaporize for ignition. Think of it this way... When you fill your lawnmower during the summer, you can literally see vapors coming out of the tank. That is vaporization, and a spark will set it off easily. Alcohols don't vaporize well at cold temps, and a spark is not as likely to set the combustion process in motion. Gasoline will vaporize in the cold, and the spark begins the process. The flame front heats the rest of the charge, and the alcohol will burn.
