Not yet the spring sun as it should be overwintered warm the frozen ground; the forests have not disappeared snowy clearing — and avid travelers at the start of the first campaigns. Out of the closets, attics get backpacks, tents, mats and sleeping bags: the most daring hikers go away for weekends, and even overnight stays. The fire, of course, heat and cold, and what a night in a tent? Here, because the fire will not be bred, and a candle it is not very warm, and dangerous.
However, the tourism fraternity of invention. Experienced Moscow travellers Roxin A. and L. Tsukanov found an ingenious way unusual “steam” heating tent. After the fire is out there, how not to use a generous heat of the fire. And they figured out how.
…That’s the place to camp, pitch a tent, and at the required distance from the already crackling fire in the twigs and hung pots for cooking simple tourist food. It’s time to take care of warm overnight. To do this, in the fire laid a piece of a metal pipe, the ends of which extend beyond burning fireplaces and burning embers. By the end, which faces the tent, it connects the outgoing hose or several tubular segments (diameter and connection by analogy with the vacuum cleaner): for him to be the heated air from the pipe in the fire, and the cold will be sucked into the other end of the pipe. And so his traction was good, it is desirable to lay the piping so that it went downhill up to the tent: the steeper, the more intensive the flow of heated air. So it was not too hot, pipe in a fire may be wrapped with asbestos or covered with clay. To adjust the temperature of the incoming air tent, covering or blocking any of the holes of the “pipeline”. Such heating is quite safe, it can be safely left for the night, how many will burn and smolder the fire.
