A liquid seems more ideally matched to the technical requirement.
In the mid 80s, power companies were toying with the idea of power
stations fueled by a coat-oil slurry. Somewhere around here I have a
short paper on the engineering of it. There was also a brief interest
in reviving oil-fired steam locomotives to replace diesels, and the
fuel being discussed was a coal-oil slurry. I think it was BMW during
WW2 which actually built and flew some coal-slurry engines (for the
Me264, if memory serves).
If Rudolf Diesel had mixed coal dust with vegetable oil ...
What was that tar type stuff that the old battleships and destroyers
ran on. they had to heat it to pump it into the engines.
Like a super- concentrated diesel, in a tar form?
bunker?
