I haven't checked the links provided, but I do know that the six stroke concept has been around for years. While it is a good concept, there are several things that need to be overcome for it to become viable, and I would rather see that money and effort put into other ideas that will be more longterm such as electric vehicles like the Volt.

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.
