my numbers were for an ideal case - of course in real life they won't be quite as accurate for many reasons:
1) you will NEVER find pure water
2) you will never find pure aluminum
3) water will begin to evaporate around 190 degrees F because of the pressure in the system and you dont know how much you lose

i would NOT recommend alcohol. remember, it is flammable and getting something flammable that hot can cause problems ...
