Was it becouse of a gas cooking? Generator? Alohol stove?
The chemistry experts just said with alcohol stove you will not get to enough CO2 and CO to bring you dead in a mac.
In the video the bring just panic but no information.
Having done some more study on the issue, I have found that your chemistry teacher is 100% correct HOWEVER that is until you put a pot or kettle on the stove to heat it.
The issue being that if the flame is left to burn all the fuel completely then the complete combustion will burn off the CO2, BUT as soon as you put a kettle or pan on the stove then the combustion is not complete causing HUGE amounts of CO2, in fact alcohol is worse than gas for creating CO2 in this instance.
The simple answer is to move the pot or kettle up off the flame around 3/4 a inch or more so the fuel has space to combust completely, HOWEVER good luck waiting for your already SLOW alcohol stove to boil your kettle or cook your food, it could take quiet a while.
So lets rephrase the question to
Question "Is it safe to run a alcohol stove in a boat with minimum ventilation?" Answer Possibly, but its not recommended
Question "Is it safe to cook on a alcohol stove on a boat?" Answer NO, Not unless you can ensure total combustion of all the fuel,
Question "Whats is the easiest way to check that fuel is completely burnt and there is no dangerous levels of CO2 when I cook
Answer: With a detector mounted low to the ground as CO2 is heavier than air so will displace it
My teacher told me once that a feather and a 1 ton weight would hit the ground at the same time if dropped from the same height, which is FALSE, until he added in that for this to work it has to be in a perfect vacuum, it all depends on what the question is and if the teacher is willing to give you the parameters in which his answer was given for it to be correct
