Re: Alcohol Stove - Non-Pressurized
"kerosene is odorless. "
Yes, I've heard a number of people including Mercedes shop managers say that. It appears to be said more often by mechanics than biologists, who would suggest that some of us simply have more sensitive noses, and some of us can smell and taste things that others literally cannot. (There are genetic differences.)
Never met anyone who could actually prove that "properly" combusted kero or diesel had no stink.
Sure, any fuel spill can explode. Including kero and diesel. That's what fuels are supposed to do, they explode. Sometimes in a more controlled or more surprising fashion than at other times. The most powerful conventional bombs in existance are ANFO, fuel-air bombs based on, you guessed it, nice safe diesel fuel.
If you want safety, you don't cook on flames. Look at all the home fires started in the kitchen. Boat fires started in the galley. Fuel? Yup, pretty much supposed to explode.
