大便是不是易燃?

在一些遍遠地方,曬乾的便便是日常的主要燃料

印度大家都燒牛屎, becasue 牛 eat grass, their 屎 is fiber, after dry under the sun, dry fiber can be burn la.

but human 屎 is nto so much fiber, except D 素食者. then, our shit even after dry, still can't burn. actually, difficult to burn.

"在一些遍遠地方,曬乾的便便是日常的主要燃料 " <- agree, but not any kind 便便,can burn. only 草食動物個d先得

在一些遍遠地方,曬乾的便便是日常的主要燃料.臭味並不一定是沼氣,就如臭腳發出的味道,並不會引起爆炸,最多只是令人昏迷,而大便後扔煙蒂進馬桶係唔會爆炸,如果會的話,好多人去廁所如廁時食煙,米炸到七彩

From my Chemistry knowledge, faeces excreted by human or other complex organisms may comtain a kind of hydrocarbon called methane, CH4, it can be heated in air to give out carbon dioxide and water. it can be a fuel to release energy. But is it flamable?it is determined by the amount of methane in the faeces. But usually, it is easy to burn because some people use them as a fuel to get warm or boil water in the nortern China.

大便不會爆.
發酵後才會有足夠濃度沼氣燃燒.
