anti freeze alternative

[betegh9]

Not to throw another monkey into the mix, but those people with water cooled engines could stay free of anti-freeze if they program their car to start, warm up and shut off automatically when the coolant (water) temperature reached 32F. How about a small engine heater while the car sits in a cold garage..... In this computer age, anything is possible. There must be an APP for this, and if not, create one and sell it to Apple. I know that some of you are now saying: "he's full of it" OK!
I read in an old book about what used to be done in the old days before AF. ALCOHOL was used in some proportion with water to prevent freezing (maybe some of you chemists would like to comment..... like Alexey), and when spilled, it would evaporate faster than the water with no additional slipping. Back before there were highways, there was a race around the world, I forget what it was called, and I read that drivers drained their coolants when they stopped for rest or any other reason in cold climates. Filled the system back up when they got started.
The point here is that people with their enginuity figured out what to do to solve a problem, now, we can't even think outside the BOX.
I would be in favor of using water in run groups white and above since changing coolant is not such a hard job to tacke for the safety of your fellow drivers.....and yourself. If you are too lazy to do this, try the alcohol route.(Maybe if you use GRAIN alcohol, you can consume it if you get desperate.)
In the mean time, I am using air to cool my car, and if I spill some of it, please let me know.
