I wouldn't read too much into this. Given the temperatures at which extreme cooling systems operate, an open system is not a realistic alternative. Extreme cooling should not be taken lightly and I'd encourage everyone to do their homework prior to beginning. However, with the right system setup, the methanol/water mixture is very tough to beat. The mixture also does not have nearly the toxicity/flammability concerns of straight methanol.

In short, yeah there are definite precautions to take, but the windshield wiper mix is about as good as it gets for operation down to -40°C.
