It was probably a link I made (in relation to Wayne's little CO test in his dining room). I never actually read through the rest of the thread (& still haven't, properly).
I've always said the same about halogen heaters. Apart from the fact they don't give off any CO, they are just as dangerous as open flame gas heaters for starting fires. They do give off a lovely glow, but should never be left running unattended. I've always given this warning, every time someone mentions a halogen heater, in the hope I may save a life, or at least a tent, some day.
& I also knew CO can burn. If you mix it with pure steam you get something called water-gas (I believe). This is very combustible, & can be used to run all sorts of things, including engines. A charcoal burner with a boiling kettle steaming into the bottom of it was what I saw on a school science video once, & they even used them to run cars & motorbikes, during the war. (It's an experiment I've been dying to recreate).
I'm glad this thread was resurrected, I love it when the "Anti-Gas" brigade see just how safe these heaters can be. Although, when they see how much gas they eat through, they may well be convinced not to use them
