This is something i first read about in The sas survival handbook by john wiseman.
It says burning a mix of oil and water will make one of the hottest fires. think he might be suggesting for use as an incinerator.
the instructions are to put oil and water in seperate cans, pierce a hole in the bottom of each and let them drip down a trough (in a mix of 2-3 drops water to 1 drop of oil) onto a heated metal plate.
You then light this mixture.
Has anyone tried this??
Also a friends grandad was an army field cook in WW2 and he said they had a cooker that worked in this way only using diesel and water. Anyone heard of that?
