It's a common food additive; ethylene glycol is a known animal poison. Relatively speaking it's a much better additive.

You know this stuff is probably just deicing solution diluted by some large amount right? I see no reason to call it snake oil though as the guy clearly states he's a retired NASA engineer that adapted their deicing chemicals to cooling electronics. The rationale for the chemicals involved makes perfect sense to me. I don't really see the big deal about electrical conductivity though. I personally dont allow my rig to leak so getting components wet doesn't scare me and isn't worth a premium. Getting better performance out of glycol coolant IS worthwhile though and so I find this an interesting solution (though I bet I can do it for a small fraction of the cost in my lab). I have deionized water and access to reagent greade chemicals in bulk though...
