My point exactly. One of the flying magazines recently recommended preheating 
your [gasoline] engine if it's 20 degrees out; if you're willing to do that 
now, your aircraft Diesel will certainly have no problems starting.
There seems to be 2 or 3 serious efforts to get a modern Diesel aircraft 
engine flying. Hopefully, at least one will make the grade.
