How to heat a tent- safely?
While I am a a hands-on person, that mostly extends to art and sculpture rather than engineering. Therefore, I thought I ought to bring this question to people with a little bit more knowhow in that area. See, with the cold winter months coming on camping is becoming a little more arduous. More to the point, heating a tent safely is a real problem. I don't trust gas powered heaters....but there's not a whole lot of alternatives out there.
So I was wondering if anyone here could think of a way to safely heat a tent for a prolonged period of time. Preferably without gas, electricity, or risk of fire.
