Ok here is another one for you, this is dealing with very high heat situation in microwave technologies needing cooling and what they use, and remember this is government that can use anything they want cause after all money is no object (they just print more) and since this is a stationary object they aren't worried about how slick it is (takes out that argument) and even when it's in a situation of below freezing temps they STILL don't recommend using antifreeze mixture.
and I still am not saying that you should run straight water, just don't try to say that a antifreeze mixture is more efficient

As a coolant for VEDs, deionized water (which is chemically stable with a high heat-transfer capability) is
much preferred over antifreeze mixtures. If protection against low temperatures is required, draining a system
or using electric water heaters during nonoperating periods will prevent the problems introduced by
antifreeze

has nothing to do with what race guys do, or not, if ethyl glycol mix was better for cooling then irrigardless if the rust etc the race guys would use it. period end of discussion. There is no dispute, there is not discussion to be had even the antifreeze companies will tell you that ethyl glycol is NOT as efficient as straight water for transfering heat out of the system. Ethyl Glycol will HOLD heat better than water (doubt this? go take a pot of water and a pot of 50/50 mix heat both to 200 degrees and take off heat at same time then check temps 10 minutes later. temp of water will be almost 20 degrees cooler)
Also I provided a link and even that guy who as you can see is NOT advocating using straight water says the same thing water is MORE effiencent at cooling than a antifreeze mixture. that is the simple and only fact here. Already said it's not a good idea in a street driven car, and I even run antifreeze in my race vehicle, and I also stated I do NOT recommend it be done but I have to make the point that the facts are and truth is antifreeze is not more efficient

Yes bear that is exactly what I am telling you, and the government, the racers, other governments the scientific community even thinks so.
Your comment is like saying you mean to tell me that in 100 yrs no one has ever developed anything that is better power production per unit than petroleum and yep it's true and why the big problems nothing puts out BTUs like gasonline so nothing can replace it 100%, sorry you can't beat nature and water is nature.
I used to believe just like you until about 4 yrs ago when it was proven to me, by....... are you ready for this....... come one now ........... the guy that Maintains MRI machines for GE medical (he is a cousin) and also backed up by one of the people that developed them (as well as red light cams) when I asked why they used water instead of some type of coolant. lets see one has a masters degree and the other has 3 doctorates but guess they don't know anything huh?
And since then I have researched it extensively and found out that when you get pst the hype of the companies that make ethyl glycol you will find that darn little is as efficient as pure water for dissipating heat. Now you can claim different you can call me names you can say I am not worth arguing with you can say whatever you want like it's physics but funny thing is I can show different in scientific data. And that is physics

Gotta figure if air is cooling water, and water is cooling something else, does not matter what that something else is, because heat is heat as long as you do not get carried away with electrolisis and a number of other factors that moving parts create , still just talking about transfering heat from something thru water to the air, and thats pretty simple..and simple is good..
