Anhydrous ammonia might make a good fuel
, but the handling issues are pretty scary. First of all NH3 spontaneously forms ammonium hydroxide on contact with water which is extremely corrosive and forms in the lungs immediately upon inhaling the fumes. There is enough moisture in the skin to do the same. I was in Pensacola Florida
in the 70's when a train derailed and a tank car of the stuff leaked. We were luck and the wind
was blowing out to sea, but one family
that lived between the track and the bay was not. All 5 died a horrible death. Three of them before the rescue
teams arrived but two lived a short while. I had a friend who was a respiratory therapist that helped work on one of the survivors. Despite having a full breathing apparatus he received 2nd degree burns on his arms and chest just from the fumes coming off the victim. I know people use this stuff for refrigeration
, but in realtively small quantities compared to what is required as fuel
. I certainly would not want large quantities of the stuff on my boat.
