I can assume that if you add wood to a fire, it will continue to burn, provided that the wood is dry, not too large, it does not run out, it does not rain or snow, the people who need this fire now do not want to sleep or eat, they do not get too hot or cold, they do not get tired, they do not get tired of talking around the fire …
On the territory of the land art exhibition of objects "Weather Forecast" in the Moscow region, three fire pits were made. Next to the fires there was wood and everything necessary to chop it. The air temperature was -11 ° C. The further fate of the fire and the heat it gave depended on the actions of the participants and some other conditions, the full list of which I do not know.
