>>1466515>>1466487Soda cans are indeed too thin for much use for biomass fuels. I'd rather not use them, since they are aluminum and so thin that there's a chance you can vaporize parts of it. "Tin" cans or rather modern food cans are normally made of steel with hot dipped/galvanized zinc coating and either plastic lining or epoxy lining. Some don't have that extra lining. The zinc is only a problem when it turns to smoke and the plastic and epoxy can be burned off fairly quickly before using. The zinc is usually not a problem unless you inhale it. If you do inhale it you'll know right away because it will make you sick (metal fume fever). It can be burned off in a short amount of time prior to cooking with it. Thus, health hazards are taken care of with a pre-burn while you watch in safety up wind.
The alcohol stoves that use soda cans are quite different. You can use those for years without any degradation to the metal at all. Their downside is that you need to make a few of them to get the design just right for making the best most efficient flame and they require liquid fuel instead of twigs and branches.
>>1465859Here's my old one. I've officially retired it after a couple years of hard use. I've been too busy with farming to go innawoods for anything other than maple sap, so I've yet to build a 3rd version. This is intended to be a camp stove, not a trail stove, and worked really well for camping and backyard cooking. Even at only 2.5lbs, it is not suited for hikers at all due to being bulky. lol
