Windshield washer fluid is around a $1.50 a gallon for 40% alcohol. I don't want or need pure methanol.

You take everything I say out of context.
Water methanol will also not give any improvement on most if not all production engines. I am talking about using water methanol on a custom built high compression blue printed engine and only under acceleration and wide open throttle. Then I can burn regular gasoline at idle and cruise. The water methanol will not be used at cruise. The water methanol will not directly increase fuel economy. My hope is that the water methanol can be added to help the regular gas preform more like premium gas when needed.
What part of that sounds like hho?

I don't think hho is "break even" . I think it's a complete waste of time and resources. Hho is one of those things that can be made to work in the lab but fails to make the transition to the real world where the perfect conditions needed to make it work rarely ever exist.

I don't think water methanol is a direct replacement for hho. Water methanol has actual effects on an engine where most if not all attempts to implement hho fail or just lower fuel economy.

Read the links in the water injection wiki. Most if not all attempts to add water to a gasoline engine lowered it's fuel economy. Again in a lab where the testers have full control over all the variables it set be made to work.
