you cant offend me. trust me, many have tried.
the whole reason I bumped this thread is to get more discussion out of it and approach it from numerous directions other than my own.
I looked into this topic seriously about a year ago (around the same time I started this thread) and no one wanted to discuss it in depth so I lost interest as well.
the methanol example was just one that I could think of off hand. im sure there are other mixtures that could be ran in order to do this.

For one, regular tap water would not do good in this system. The impurities and salts present in tap water would just eat away and leave deposits in the combustion chamber. DI water could be used, but the cost of it would most likely negate your fuel savings.
There is the freezing issue that has been mentioned before. I haven't studied how methanol addition affects the freezing point of water. It's freezing point, -143F, is about 30 degrees higher then that of ethanol. For comparison, a 5% ethanol in water solution, beer, will freeze in a freezer, but a 40% solution, liquor, won't. These are ethanol solutions, and I can't say how methanol will compare, but it might take a considerable amount of methanol to provide adequate freezing protection which again increases cost.

the concepts been around for a while. and I dont see it making much progress into automotive technology, but maybe for industrial generators and the like would be a better direction for it to go.
the regular tap water comment makes me wonder tho, cus I know a few people who run water injection with tap (most use distilled, but a few still use the tap and havent run into problems).
as for the freezing problem, that could be more than likely be easily solved with a glow plug, heater coil, or blanket setup. then you have to remind consumers to plug their car in at night. however, there are a lot of people now who run heater blankets on their oil pans and engine blocks in winter areas for just this problem.
