Hello, I wanted to know if anyone had any tips in regards to keeping an (reasonable) outdoor flame active on a balcony or other urban environment that would require a shitty camp stove. I have purchased a small camp stove ( 4 walls and a top, basic) and want to know how, in an urban environment, without camp blocks, canned burners, etc, to keep the fire going to cook food, boil water, etc for a reasonable amount of time with minimal (available urban) resources. Sorry if this has been posted before, but I haven't seen anything. I'm trying to build a basic BOB/urban survival kit, and I know I can improve. Please offer any practical tips you have for URBAN prep, I would appreciate it. Thanks!
