Pretty cool stuff,
 
The stuff does have a higher boiling point, however we are severely restricted to our max cooling temps to begin with-- unless you don't like your "o" rings. Will the increased boiling point mitigate point boiling or will it do the same as our pressure water/glycol system?
 
My understanding is that the material runs at atmospheric pressure, and that is nice. how do it's characteristics vary when at altitude?
 
My further understanding is that the material is quite costly and cannot be mixed with H2O under any circumstance. If switching over, the H2O must be thoroughly purged from the system.
 
My further further understanding is that  it is quite rare in the field and that if you have to top off, for any reason, as stated before, you can't just add water (unless you drain the entire system) or wait until the automotive people can supply you.. or you can carry a gallon of so if it along with your pre-mix.
 
At one time, I was very interested in it's potential for my aircraft, however I don't think it is ready for prime-time, at least in me

While on the subject of cooling, I am curious if anyone has tried the waterless coolant? Seems to offer some advantages, namely higher boiling boint and low pressure, is there any reason it should not be used in our aplication?
